■Engineering data and characteristics

Approximate Values for three-phase Motors

Motor Full Load Currents

Approximate values of motor F.L.C. and minimum „slow blow“ respectively „gL“ short-circuit fuse

The motor F.L.C. be valid for standard internal and surface cooled three-pole

motors with 1500 min-1. The fuses values be valid for the motor F.L.C. shown in

the table and D.O.L.-start: starting current max. 6x motor F.L.C., starting time

max. 5s; star-delta-start: starting current max. 2x motor F.L.C., starting time

max. 15s. For motors with higher F.L.C., higher starting current and / or longer

starting time, larger short-circuit fuses are required.

The maximum admissible value is dependent on the switchgear

respectively thermal overload relay.

Contact Life

For selection of the suitable contactor-type according to supply volt-

age, power rating and application (utilization category AC1, AC3 or

AC4) use contact life characteristic diagram.

For the most common supply voltages four scales of power ratings Pn

are provided for each utilization category.

Select contactor-type according to utilization category AC3 (breaking

current Ia = Ie) using the motor rating scales to the right, according

to utilization category AC4 (breaking current Ia = 6 x Ie) using the

motor rating scales to the left.*1

Select contactor-type according to utilization category AC1 (breaking

current Ia = Ie/AC1) using the breaking current scale.*1

For contactors frequently used under AC3/AC4-mixed service condi-

tions calculate contact life with the formula:

1. Pay attention to the approved rated values of the selected

contactor according to the national approvals

Specifications

■Engineering data and Characteristics

Thermal Overload Relays, tripping times for selection to motors of protection degree EEx e

Relays With Standard Tripping Characteristic

When selecting a standard overload, refer to the tripping curve.

Determine the values of the starting current ratio IA/IN and the time tE

which is marked on the label of the motor. The overload must trip

within the tE time, which means that the tripping curve from cold con-

dition must be (20% due to tolerance) below the coordination point IA/

IN and the time tE.

IA= Starting current of motor

IN = Rated current of motor

tE = tE-time of motor

All tripping times of overload relays J7TKN-A are shorter than the

minimum values of the tE time for motors of protection degree EEx e

acc. to EN 50019 and therefore are suitable for all motors of protec-

tion degree EEx e. For these overload relays the selection on basis

of tripping curves is thereby not necessary.

Labels of tripping curves for each setting range, sized 148x105mm

(self-adhesive) are available on request.

Specify type and setting range.

Setting Range Tripping time depending on the multiple of the

current setting from cold condition (tolerance

±20% of the tripping time)

Temperature Compensation

In case of higher ambient temperature use the following formula:

(Ambient temperature - 20) x 0.125 = correction factor in % of the

full load motor current

Example:

Ambient temperature 70°C, full load motor current 7A

(70 - 20) x 0.125 = 6.25%

Technical Data according to IEC/EN 60947-1, 60947-2, 60947-4-1 and VDE 0660

This table shows the rated ultimate short-circuit breaking capacity Icu

and the rated service short-circuit breaking capacity Ics of the J7MN

circuit-breakers with different operational voltages as a function of

the rated current In of the circuit-breakers.

The circuit-breakers can be fed at the top or bottom supply terminals

without any reduction of the rated data.

If the short-circuit current exceeds the rated short-circuit breaking

capacity of the circuit-breaker specified in the tables at the

installation point, a back-up fuse is to be used.

The maximum rated current for the back-up fuse is specified in the

tables. These fuses are only suitable for the short-circuit-currents as

indicated on the fuses.

Motor Protection Circuit Breaker (MPCB) J7MN H-79

LVSG

Description

J7MN circuit-breakers are compact, current-limiting circuit-breakers

which are optimised for load feeders. The circuit-breakers are used

for switching and protecting three-phase induction motors of up to

18,5 kW at AC 400 V and for loads with rated currents of up to 40 A.

Construction

The circuit-breakers are available in three sizes:

J7MN-12 overall width 45 mm. Max. rated current 12 A. Suitable for

3-phase induction motors of up to 5.5 kW at voltages of 400 V AC.

J7MN-25 overall width 45 mm. Max. rated current 25 A. Suitable for

3-phase induction motors of up to 11 kW at voltages of 400 V AC.

J7MN-50 overall width 55 mm. Max. rated current 40 A. Suitable for

3-phase induction motors of up to 18,5 kW at voltages of 400 V AC.

Releases

Circuit-breakers J7MN are equipped with bimetallic-based, inverse-

time delayed overload releases and with instantaneous overcurrent

releases (electromagnetic short-circuit releases).

The overload releases can be set in accordance with the load cur-

rent. The overcurrent releases are permanently set to a value 13

times the rated current and thus enable trouble-free start-up of

motors.

The scale cover can be sealed to prevent unauthorized adjustments

to the set current.

Operating mechanisms

circuit-breakers J7MN-12 are actuated via a switch operating mecha-

nism and circuit-breakers J7MN-25 and J7MN-50 via a rotary operat-

ing mechanism. If the circuit-breaker trips, the rotary operating

mechanism switches to the tripped position to indicate this. Before

the circuit-breaker is reclosed, the rotary operating mechanism must

be reset to the 0 position by hand, in order to prevent the former from

closing by mistake before the fault has been cleared.

In the case of circuit-breakers with rotary operating mechanisms,

there is an electrical signal via a signalling switch to indicate that the

circuit-breaker has tripped.

All operating mechanisms can be locked in the 0 position with a pad-

lock (shackle diameter 3.5 to 4.5 mm).

The J7MN circuit-breakers fulfil the isolation characteristics specified

in IEC 60 947-2.

Operating conditions

Circuit-breakers J7MN are suitable for use in any climate. They are

designed for operation in enclosed rooms under normal conditions

(e. g. no dust, corrosive vapours or harmful gases). Suitable enclo-

sures must be provided for installation in dusty or damp rooms.

Circuit-breakers J7MN can also be fed from below. The standards in

accordance with which the circuit-breakers are constructed, the per-

missible ambient temperatures, the maximum making and breaking

capacities, the tripping currents and other boundary conditions can

be found in the technical data and tripping characteristics.

Since the operational currents, starting currents and current peaks

vary as a result of the inrush current, even in the case of motors with

identical output ratings, the values specified for these output ratings

in the selection tables are intended as a guide only. The specific

rated and start-up data of the motor to be protected is always para-

mount to the choice of the most suitable circuit-breaker.

In order to prevent premature tripping due to phase failure sensitivity,

the circuit-breakers should always be connected in such a way that

current flows through all three main conducting paths.

Short-circuit protection

The short-circuit releases of J7MN circuit-breakers disconnect the

faulty load feeder from the system in the event of a short circuit and

thus prevent any further damage.

Circuit-breakers with a short-circuit breaking capacity of 50 kA or

100 kA at a voltage of 400 V AC are practically short-circuit-proof at

this voltage, as higher short-circuit currents are not usually encoun-

tered at the installation point.

Back-up fuses are only necessary if the short-circuit current at the

installation point exceeds the rated ultimate short-circuit breaking

capacity of the circuit-breakers.

Motor protection

The tripping characteristics of J7MN circuit-breakers are designed

mainly to protect three-phase induction motors. The circuit-breakers

are therefore also referred to as motor circuit-breakers. The current

of the motor to be protected is set with the aid of the scale.

Circuit-breakers with thermal overload releases are normally

designed in accordance with release Class 10.

Line protection

J7MN circuit-breakers for motor protection are also suitable for line

protection. In order to prevent premature tripping due to phase failure

sensitivity, the three conducting paths must always be uniformly

loaded. The conducting paths must be connected in series in the

case of single-phase loads.

The J7MN circuit-breakers meet the isolation conditions of

IEC 60 947-3 as well as the additional test conditions for circuit-

breakers with isolation characteristics specified in IEC 60 947-2. Tak-

ing IEC 60 204-1 into consideration, they can thus be implemented

as main and EMERGENCY STOP switches.

Door-coupling rotary operating mechanism do not fulfil the isolation

characteristics specified in IEC 60 947-2. Door-coupling rotary oper-

ating mechanism according isolation characteristics specified in

IEC 60 947-2 on request.

H-80 Motor Protection Circuit Breaker (MPCB) J7MN

Characteristics

The time/current characteristic, the current limiting characteristics

and the I²t characteristics were determined in accordance with

DIN VDE 0660 and IEC 60 947.

The tripping characteristic of the inverse-time delayed overload

releases (thermal overload releases or ’a’ releases) for DC and AC

with a frequency of 0 to 400 Hz also apply to the time/current charac-

teristic.

The characteristics apply to the cold state. At operating temperature,

the tripping times of the thermal releases are reduced to approxi-

mately 25 %.

Under normal operating conditions, all three poles of the device must

be loaded. The three main conducting paths must be connected in

series in order to protect single-phase or DC loads.

With 3-pole loading, the maximum deviation in the tripping time for 3

times the setting current and upwards is ± 20 % and thus in accor-

dance with DIN VDE 0165.

The tripping characteristics for the instantaneous, electromagnetic

overcurrent releases (short-circuit releases or ’n’ releases) are based

on the rated current In, which is also the maximum value of the set-

ting range for circuit-breakers with adjustable overload releases. If

the current is set to a lower value, the tripping current of the ’n’

release is increased by a corresponding factor.

The characteristics of the electromagnetic overcurrent releases

apply to frequencies of 50/60 Hz. Appropriate correction factors must

be used for lower frequencies up to 16 2/3 Hz, for higher frequencies

up to 400 Hz and for DC.

The characteristic shown here is a schematic representation of cir-

cuit-breakers for all ranges.

Time/current characteristics, current limiting characteristics and I²t

characteristics are available on request.

●Precautions

■Notice

Use under rated condition, otherwise contactors will not only cause

malfunction, but also cause a fire or damage the contactor.

Life period of contactor depends on the operating application. Please

check the electrical life under real application in advance.

If you continue to use malfunctioning contactor, a fire or breakdown

may occur.

Do not miss-wire or miss-charge the power supply, otherwise the

contactor does not work correctly.

Do not operate in places with explosive or flammable gas, otherwise

a fire or explosion may occur by arc or heating from contactor.

Make sure to use the circuit well considered about safety, in case

there is any possibility to cause secondary disaster by contact trou-

ble (welding, faulty contact).

Do not supply short-circuit current to electromagnetic switch (contac-

tor with thermal relay). Doing so may result failure in heater of ther-

mal relay. Please use short-circuit protection like fuse or protective

circuit breaker.

Do not use a contactor or thermal relay which has been dropped or

dismantled. Doing so may cause malfunction or a fire.

Make sure to shut off power supply to contactors before wiring or

replacing.

Do not operate the actuator of a contactor manually. Doing so may

cause contact welding by chattering or burn out by arc.

■Correct use

General use

Unexpected malfunction may occur in real application. Please carry

out as many tests as possible.

Ratings in this catalogue measured under the condition according to

IEC unless otherwise specified. In cases of check by real application,

please carry out the test under the same condition as expected in the

actual application.

Selection

Coil specification

Please select suitable coil to circuit design, otherwise malfunction

may occur or coil may have a burn out by overvoltage etc.

Type

Please check contact ratings, switching capacity, thermal character-

istics etc. when selecting product type.

Thermal relay

Motor current differs by supplier, type, number of poles, frequency.

Please confirm operational current level.

Coil surge suppressor

Coil surge suppressor type should be selected by contactor type,

auxiliary relay type and applied voltage. Make sure to use defined

each contactor.

In case of installing coil surge suppressor, please check the actual

circuit because the release time will be delayed.

Electrical life expectancy

Electrical life expectancy tests in this catalogue are based on IEC.

Circuit design

Supplied voltage waveform for input

Make sure to apply and remove the voltage instantly. Do not use

under the condition that the coil voltage waveform increases or

decreases gradually.

In case of DC contactor use (input voltage

ripple)

Please use DC contactor input voltage with a ripple ratio less than

5%. Excessive ripple (pulsating current) may cause contact welding.

Fluctuation of input voltage

Make sure to supply sufficient voltage to actuate contactors properly.

Continuous supply of insufficient voltage results in excessive heating

and may cause burn out of coil.

Maximum applied voltage

Do not supply the voltage over the maximum rated voltage, otherwise

burn out or insulation failure may occur.

The temperature inside control panel has much influence to the coil

temperature, so make sure not to exceed the specified value in the

catalogue.

Basically rated voltage should be supplied to coil. To supply higher

voltage than rated would result in shorter electrical life, even if it is

lower than the maximum rated voltage.

Reverse

Make sure to use reversible contactors for reverse operation.

Make sure to use interlock device in reverse operation by two contac-

tors, otherwise short circuit current may burn out or give damage to

contactors and motors.

Unless otherwise stated in the catalogue,

modifications, especially those of stated values,

sizes and weights are subject to alternation.

Diagrams and tables are subject to alternation and

not to be regarded as binding drawings.

H-84 Appendix

Installation

Mounting

Make sure to use specified wire size, mounting screw size, mounting

screw number, and DIN rail size.

Tightening Screw

Tighten each screw securely by specified tightening torque. Loose

tightening may cause a fire by excessive heating.

Combination

Please use only OMRON product combinations in case of thermal

relay, timer block and auxiliary contact block etc.

Wrong-combinations may result in damage to contactors.

Mounting direction

Some products have a defined specific mounting direction. Please

refer to datasheet before use.

Operation ambience

Dust

Dust on the surface of the contacts could result in contact malfunc-

tioning. Take countermeasure in excessive dusty surrounding.

Temperature, humidity

Use contactors within the temperature and humidity conditions spec-

ified in datasheet. To use or store contactor in excessive temperature

or humidity may result in malfunction of contact by organic film com-

posed by sulfication and oxidation on the surface of the contacts.

Use contactors within the temperature and humidity conditions spec-

ified in the datasheet, to prevent contactors from insulation resis-

tance failure by condensation or insulation resistance deterioration

by tracking.

Gas

NH3, H2S, SO2, CI2, Si and NO2 have bad effects on a contactor.

With these gases, a corrosive metal film ist generated on the surface

of the contacts and could result in contact malfunctioning. Use a con-

tactor in low humidity and no corrosive gas surroundings.

Oil

Do not use a contactor in places where oil is sprayed onto the con-

tactor. It will cause cracks on polymer parts.

Shock and vibration

Do not use a contactor in places where there is excessive shock or

vibration. It may cause malfunctioning.

Storage

Store contactors in a place with no direct sunshine or ultraviolet rays.

It will cause crack on polymer parts.

When contactors are to be stored for a long time, they must be stored

with care. Though it generally depends where contactors are stored,

deterioration of contacts may occur after long storage. Please check

the characteristics before use after long time storage.

●European Standards

■IEC 947, EN 60947

European Standards for Low-Voltage Switchgear

For Europe and most other industrial countries of the world, the new

IEC 947 and EN 60 947 specifications for low-voltage switchgear

have unified the regulations which previously varied from nation to

nation.

This required the introduction of new terms, and new test methods

and utilization categories. The new specifications are aimed

primarily at manufacturers. However, the user also will come across

new technical terms and data in the manufacturers’ catalogues

and on the devices themselves which are important for the selection

and application of the devices. The present paper deals with the cur-

rently published specifications. Further specifications and

supplements are in preparation.

Since 1993, all low-voltage switchgear purchased in Europe had to

satisfy the EN 60 947 European Standard. Installations in existence

prior to 1993 are not affected by the standard and need not to be

refitted with new devices. Devices constructed and tested to the IEC

standards and EN standards can be used worldwide, with the excep-

tion of the USA and Canada. In these countries UL and CSA specifi-

cations continue to apply. Switchgear which conforms to IEC 947

and EN 60 947 and which has, in addition, UL- and CSA approvals,

in the meantime has entered the market. Such ‘world market’ devices

offer the advantage that they can be used throughout the world,

including the USA and Canada.

2: The tests are to be carried out with an incandescent light load.

3: The test data are to be derived from the test values for AC-3 or AC-4 according to

Table VIIb, EN 60947-4-1.

4: AC-3 category may be used for occasional inching (jogging) or plugging for limited

time periods such as machine set-up; during such limited time periods the number

of such operations should not exceed five per minute or more than ten in a ten

minute period.

5: A hermetic refrigerant compressor motor is a combination consisting of a compres-

sor and a motor, both of which are enclosed in the same housing, with no external

shaft or shaft seals, the motor operating in the refrigerant.

Note 1: The value “6 x P” results from an empirical relationship which is found to represent most DC magnetic loads to an upper limit of P = 50 W, viz 6 x P = 300 ms. Loads having power

consumption greater than 50 W are assumed to consist of smaller loads in parallel. Therefore, 300 ms is to be an upper limit, irrespective of the power consumption value.

Protection against electrical shock, to IEC 536

IEC 536 covers the setting up of electrical apparatus, and its

arrangement in electrical installations with rated voltages up to 1000

VAC and 1500 VDC, with regard to protection against direct contact

where operating elements such as push-buttons and switches are

located in the vicinity of live parts.

“Finger-proofing” relates only to the operating device, and only in the

normal direction of operation. A clearance of at least 30 mm radius

from the centre point of the device to any live parts, must be ensured.

The IP 20 degree of protection is superior to “finger-proofing” in that

it embodies protection against contact with electrical apparatus in

any direction. Devices which are “finger-proof” and of IP 00 degree of

protection can be provided with further protection against contact in

the form of shrouding, if so desired.

Damp heat, constant, to IEC 68 Part 2-3

In this test, the effects of a constant high level of humidity

(93 +2/-3%) and a constant temperature (40 ±2)°C over a prescribed

duration, are observed.

Damp heat, cyclic, to IEC 68 Part 2 - 30, Test Db

This test is used to assess the suitability of electrical products for

operation and storage at high relative humidity levels, in conjunction

with cyclic temperature fluctuation. A test cycle consists of 12 hours

at 40 ±2°C, with relative humidity of 93 ±3%, and 12 hours at

25 ±3°C, with the relative humidity of at least 95%.

Ambient temperature

Ambient temperature is the temperature of the room (e.g. factory bay

or switchgear room), in which the open or enclosed device is

installed, a prerequisite being that this temperature is not significantly

influenced by the heat losses from the device.

●Glossary of standard terms

This Glossary offers brief expIanations of some of the standard

terms used in this catalogue. However, it must not be regarded as a

substitute for the actual text of the standard, especially where the

new terms used in IEC 947 are concerned.

Reference is therefore made aIongside each such term to the reIev-

ant section of the standard, e.g. IEC 947-1 in addition, IEV numbers

are given to enable you to find foreign language equivalents in the

International EIectrotechnicaI Vocabulary

(IEG 50), if required.

motor-protective circuit-breaker, can carry for the duration of the pro-

tective device tripping time.

Mininum command time

tion necessary to initiate tripping.

Rated breaking capacity

(IEC 947-1; 4.3.5.3)

The r.m.s. value of current which a switching device is capable of

breaking according to its utiIization category. The rated breaking

capacity is stated by reference to the rated operational voltage and

to and incIuding its rated breaking capacity stated.

Rated actuating voltage Uc

(rated control circuit voltage)

(IEC 947-1; 4.5.1)

trol circuit. Due to the presence in the controI circuit of transformers

or resistors, this voltage may differ from the rated control supply volt-

age.

Rated service short-circuit breaking capacity Ics

(IEC 947-2; 4.3.5.2.2)

The prospective short-circuit current which, depending on the rated

operationaI voltage, a circuit-breaker is capable of breaking repeat-

edly (test cycle: O - CO - CO; previousIy P-2). After interrupting this

current vaIue, the circuit-breaker must be capable, despite its own

thermal level having increased, of continuing to carry and disconnect

in the event of overIoading, the rated uninterrupted current.

Rating or rated power

(IEC 947-1; 4.3.2.3)

The rated operational power which an equipment is capable of

switching at the associated rated operational voItage in accordance

with the utilization category.

motor contactor utilization category AC-3: 37 kW at 400 V.

Rated operational voltage Ue

(IEC 947-1; 4.3.1.1)

The voItage to which the characteristics of an equipment are

referred. The rated operational current must not in any case exceed

the rated insulation voltage.

(IEC 947-1; 4.3.2.3)

The current which an equipment is capabIe of carrying taking into

account the rated operational current, duration of operation, utiliza-

tion category and ambient temperature.

Rated uninterrupted current Iu

(IEC 947-1; 4.3.2.4)

(IEC 947-1; 4.3.5.2)

The vaIue of current which an equipment is capabIe of switching On

in accordance with the utilization category and at the rated opera-

tional voltage.

Rated frequency

(IEG 947-1; 4.3.1 .2)

The voltage to which insulation tests and creepage distances of an

equipment are referred. The maximum operationaI voltage must not

in any case exceed the rated insulation voltage.

Rated short-circuit breaking capacity Icn

(IEC 947-1; 4.3.6.3)

switching Off at rated operational voItage and rated frequency, and

without sustaining damage. It is expressed as r.m.s. value.

Motor rating

(IEC 947-1; 4.3.2.3)

Power output of a motor at the associated operational voltage.

Rated control supply voltage Us

(IEC 947-1; 4.5.1)

The voltage applied to the input terminals of the control circuit of an

equipment. Due to the presence of transformers or resistors in the

control circuit, this may differ from the rated actuating (control circuit)

voltage.

H-90 Appendix

Rated impulse withstand voltage Uimp

(IEC 947-1; 4.3.1 .3)

Measures the stability of the internal clearances of an equipment

against overvoltage peaks. The utilization of suitable switchgear can

ensure that overvoltages are prevented from transferring from the

mains to deenergized system sections within it.

Rated current In

(of a circuit-breaker)

(IEC 947-2; 4.3.2.3)

For circuit-breakers, this current value is equal to the uninterrupted

current and the conventional free air thermaI current.

Protection against direct contact

Design measures incorporated into equipment in order to prevent

direct contact, i.e. without tools, with live parts of a system (finger

proof, back-of-hand proof).

Control circuit reliability

Measures the probability of switching states arising during the

lifespan of a contact, which would be interpreted as faults by down-

stream electronic controllers (PLCs). Control circuit reliability is

expressed in values based on tests using standard limit values for

signal inputs.

Damp heat, constant

This test subjects the equipment to an ambient temperature of 40°C

at a constant humidity of 93%. At set intervals during the test, the

electrical and mechanical function of the equipment are examined.

Damp heat, cyclic

This test subjects the equipment to cyclically changing climatic con-

ditions: a cycle applies 40°C ambient temperature at 93% relative

humidity for 12 hours, followed by 12 hours of 25°C at 95% relative

humidity. At set intervals during the test, the electrical and mechani-

cal function of the equipment are examined.

Finger proof

An equipment whose live parts cannot be touched by the operator

during actuation is termed finger proof. This also affects operator

activity on neighbouring switching devices. The finger proof area of a

push-actuated operating medium is a circular area of at least 30 mm

radius around the actuating element, and vertical to the direction of

actuation.

Within this circular area, touch-critical parts must be located at not

less than 80 mm depth under the actuating level.

Utilization category

(IEC 947-1; 2.1 .18/IEV 441-17-19)

A combination of specified requirements relating to the condition in

which the switching device or the fuse fulfills its purpose, selected to

represent a characteristic group of practical applications. The speci-

fied requirements may concern, e.g. the values of making capacities,

breaking capacities and other characteristic values, data concerning

associated circuits, and the relevant conditions of use and behaviour.

(IEC 947-2; 4.4)

For circuit-breakers, the utilization category denotes whether the

equipment is designed for selectivity using time delay (category B) or

not (category A).

Back-of-hand proof

An equipment whose live parts cannot be touched by a sphere of

50 mm diameter, is regarded as back-of-hand proof.

Altitude

The density of air decreases with increasing altitude, and this

reduces its insulating capacity as well as its heat transfer capability.

The rated operational voltage and current of switching devices, con-

ductors and motors as well as the tripping behaviour of thermal over-

load relays are affected by this.

Upon request, OMRON ELECTRONICS will supply information as to

the suitability or otherwise of switchgear for operation at altitudes

above the 2000 m limit specified by the standard.

Conventional free air thermal current

(IEC 947-1; 4.3.2.1)

The maximum value of current which an equipment is capable of car-

rying for a minimum of eight hours without thermal overloading. As a

rule, it corresponds to the maximum operational current.

Creepage path

(IEC 947-1; 2.5.51/IEV 151-03-37)

The shortest distance along the surface of the insulating material

between two conductive parts. The creepage distance is determined

by the rated insulation voltage, the pollution degree and the creep-

age current resistance of the material used.

Clearance

(IEC 947-1; 2.5.46/IEV 441-17-31)

The distance between two conductive parts along a string stretched

the shortest way between these conductive parts. The clearance in

air is determined by the rated impulse withstand voltage, overvoltage

category and pollution degree.

Appendix H-91

LVSG

Emergency-stop switching device

Switching device within an emergency-stop circuit which is intended

to prevent danger to persons, damage to machinery or working

materials.

Opening delay

(IEV 441-17-36)

The interval of time between the specified instant of initiation of the

opening operation and the instant when the arcing contacts have

separated in all poles. The opening time is the sum of the tripping

time and the inherent delay of the contacts.

Closing delay

The interval of time between the instant of command and the first

make operation of the contacts of the first pole to close. The closing

delay is made up of the response delay and the closing time.

Shock resistance

The capacity of an equipment to withstand pulse-like motions without

changing its operating status or sustaining damage. No contact lifting

must take place on devices in the On position, the main contacts

must not knock against each other in the Off position. A safety switch

must not trip, and control circuit switches must not change their

switching status.

Safe isolation

(IEC 536, DIN VDE 0106 Part 101)

Isolation of circuits not carrying dangerous voltages (e.g. protective

extra-low voltage) from circuits in which dangerous voltages flow.

Such isolation is achieved by means of reinforced or double insula-

tion which reliably prevents voltage transfer from one circuit to

another. This might otherwise take place between main circuits and

control circuits in switching devices or between transformer primary

and secondary. ”Safe isolation” is a priority requirement for safety cir-

cuits and functional low-voltage circuits.

Isolating function

(IEC 947-1; 2.1.19)

Equipments are deemed to possess this isolating function provided

their switching contacts when in the open position, achieve the sepa-

ration distance prescribed for the isolation of electrical circuits, and

their creepage paths and clearance distances are of the required

size. The power supply to the entire installation or a section of the

installation can thus be cut off for safety reasons, e.g. during mainte-

nance.

Tamper proof

An emergency-stop switching device is regarded as tamper proof

provided it cannot be reset without tools or via a prescribed proce-

dure, after tripping has taken place. The device latches in the tripped

position. Accidental or deliberate manipulation (inching) is thus ruled

out.

Overvoltage category

(IEC 947-1; 2.5.60)

Conventional number for prospective overvoltages at the point of

installation, as might be caused for example by the effect of lightning

or switching processes. The overvoltage category applicable to

industrial switchgear is III. The applicability of switchgear according

to the overvoltage categories is defined as follows:

Overvoltage category IV:

Use allowed directly at the termination point of the installation

(directly affected by any lightning), e.g. at an overhead line connec-

tion point.

Overvoltage category III:

Operating media with special requirements as to the serviceability for

connection in fixed installations, which are protected by overvoltage

diversion measures, e.g. circuit-breakers in low-voltage distribution

systems or in control systems for industrial use.

Overvoltage category II:

Power consumers for connection to fixed installations, e. g. house-

hold appliances, electrical tools.

Overvoltage category I:

Operating media for connection to circuits containing overvoltage

protection schemes, e.g. electronic devices.

Ambient temperature, open

(IEV 441-11-13)

Room temperature for example of the workshop or switch room in

which the switching device is located.

Ambient temperature, enclosed

(IEV 441-11-13)

Temperature at which the switching device is capable of being oper-

ated within a closed housing. For this purpose, it must be taken into

account that the heat losses of the device will add to the internal tem-

perature rise within the enclosure.

Losses

(IEV 151-03-18)

The difference between the input power and the output power of a

device. The main type of loss in electrical power distribution switch-

gear and operating media is current heat loss.

Pollution degree

(IEC 947-1; 6./1.3.2)

Conventional number for the prospective quantities of conductive

dust and humidity which can lead to a reduction in the control circuit

reliability of a device. The pollution degree is described by the follow-

ing influencing factors:

Pollution degree 1:

No pollution or only dry, non-conductive pollution occurs. The pollu-

tion does not affect the control circuit reliability.

Pollution degree 2:

Usually, only non-conductive pollution. However, transient conductiv-

ity through condensation is to be expected.

Pollution degree 3: (switchgear for industrial use)

Conductive pollution or dry, non-conductive pollution which is ren-

dered conductive through condensation.

Pollution degree 4:

The pollution leads to long-term conductivity, e.g. pollution by con-

ductive dust, rain or snow.

H-92 Appendix

Coordination type

Status of a switchgear combination (motor starter) during and after

testing at rated conditional current:

Coordination Type “1“:

- No risk to persons or installations

- No requirement for immediate readiness for renewed operation

- Damage to the starter is permissible

Coordination type “2“:

- No risk to persons or installations

- Starter is capable of renewed operation

- No damage to the starter with the exception of a slight welding of

the contacts, provided they can be separated without significant

deformation.

Positive opening operation

(IEC 947-1; 2.4.11/IEV 441-16-12)

This opening operation is designed to ensure that auxiliary contacts

of a switching device are always in the respective positions corre-

sponding to the open or closed position of the main contacts. The

contacts of a contactor are interlocked opposing contacts, pro-

vided they are mechanically linked in such a way as to ensure that

normally open and normally closed contacts can never be closed

simultaneously.

This arrangement must also ensure that minimum contact separation

of 0.5 mm is maintained over the entire lifespan of the device, even

during a fault, e.g. the welding of one contact.

The relevant German Trade Association requires the use of contac-

tors with interlocked opposing contacts for control systems on power

presses in the metal processing industry.

Positive/enforced

operation/actuation

This describes an arrangement where a link between the actuator

and the switching element ensures that the force exerted on the actu-

ator is transferred directly, i.e. without the intervention of sprung

parts, onto the switching element.

Positive opening

(IEC 947-1; 2.4.10/IEV 441-16-11)

An opening operation which ensures that the main contacts of a

mechanical switching device have attained the open position when

the actuator is in the Off-position.

Test Authorities, Registration Mark, Approvals

OMRON Low voltage switchgear is built and tested to national and

international specifications. All devices suit all important specifica-

tions without any test obligation, like VDE, BS and also relative to

IEC Recommendations and to European Standards like IEC 947 and

EN 60947.

It is for this reason OMRON Low voltage switchgear is used all over

the world. In order to provide special versions, limitations to the max.

voltages, currents and power ratings or special markings are some-

times necessary.

OMRON Low voltage switchgear is also suitable for applications in

marine environments.

They are classified in "Lloyd`s Register of Shipping" and in the "Mari-

time Register of Shipping" (GUS). The "American Bureau of Ship-

ping" does not claim a general approval for single components, the

complete electrical equipment on board has to be approved. The

devices should have UL- and CSA-approvals. Further information for

Guide-No. and File-No. (CSA, UL) you will find on page 95.

Marking of auxiliary contacts

At several devices in UL-data are two voltages for auxiliary contacts

mentioned (e. g.: 600 volts at same potential, 150 volts at different

potentials). That means, if the voltage is higher than 150 volts, the con-

trol voltage applied to input terminals must be at the same potential

■Technical information

Degree of protection acc. to EN60947

Protection ratings are prefixed by the internationally agreed letters IP

followed by two digits.

1st digit: Pertains to solid objects

2nd digit: Pertains to water.

Terminal markings acc. to EN50011

Auxiliary contacts of AC contactors and contacts of contactor relays

and thermal overload relays are particularly marked. The terminal

markings of normally-open contacts are printed as positive figures,

they of normally-closed contacts as negative figures.

This gives a clear indication of the function of the contacts.

The figure below illustrates the determination of terminal markings

for contactors with auxiliary contact blocks.

Resistance to climatic conditions acc. to IEC 68

Open-type devices are climate-resistant in the constant climate

according to IEC 68-2-3 (this is a climate with an ambient tempera-

ture of 40°C and an atmospheric humidity of 90 to 95%).

Enclosed devices are climate-resistant in an alternating climate

according to IEC 68-2-30 (this is a moist alternating climate with a

24-hour cycle between climates with an ambient temperature of

25°C, and an atmospheric humidity of 95 to 100% and an ambient

temperature of 40°C, and an atmospheric humidity of 90 to 96% in

the presence of condensation during rises in temperature).

Data are valid up to an altitude of 2000m above sea level.

Short circuit protection

Back up fuses should be used to protect contactors and starters

against short circuits. For starters the device with the smaller admis-

sible fuse at the main and at the control circuit (contactor or thermal

overload) determines the fuse size.

After a short circuit devices have to be checked for correct operation.

Disconnect power before proceeding with any work on the equipment!

Short description Definition

1 Protected against-

dripping water

Dripping water (vertically falling drops)

shall have no harmful effect.

2 Protected against

dripping water

when tilted up to

15°

Vertically dripping water shall have no

harmful effect when the enclosure is tilt-

ed at any angle up to 15° from its nor-

mal position.

3 Protected against

spraying water

Water falling as a spray at an angle up

to 60° from the vertical shall have no

harmful effect.

4 Protected against

splashing water

Water splashed against the enclosure

from any direction shall have no harm-

ful effect.

5 Protected against

water jets

Water protected by a nozzle against the

enclosure from any direction shall have

no harmful effect.

6 Protected against

heavy seas

Water from heavy seas or water pro-

jected in powerful jets shall not enter

the enclosure in harmful quanties.

7 Protected against

the effects of im-

mersion

Ingress of water in a harmful quantity

shall not be possible when the enclo-

sure is immersed in water under stan-

dard conditions of pressure and time.

8 Protected against

submersion

No ingress of water.

The complete terminal marking according

to EN 50011 and EN 50012 results from the

sequence numbers on the contactor relay

or ac contactor (2., 3.) and the function

numbers on the auxiliary contact blocks

(e. g. .1, .2, or .3, .4).

Rated currents of 3-phase motors (approx. figures for squirrel-cage motors)

Minimum fuse size for protection of 3-phase motors

The maximum size is determined by the requirements of the switchgear or overload relay.

The rated motor currents are for standard 1500 r.p.m. 3-phase enclosed ventilated and totally enclosed fan-cooled motors.

D.O.L. starting: Maximum starting current 6 x rated motor current. Maximum starting time 5 s.

Y/D starting: Maximum starting current 2 x rated motor current. Maximum starting time 15 s.

Set overload relay in the phase lead to 0.58 x rated motor current.

Rated fuse currents for Y/D starting are also valid for 3-phase motors with slip-ring motors.

For higher rated currents, starting currents and/or longer starting times, larger fuses are required.

Table is valid for “slow” and/or “gL” fuses (DIN VDE 0636).

For NH fuses with aM characteristics, fuses = rated current is selected.

H-102 Appendix

Minimum fuse size for protection of 3-phase motors

The maximum size is determined by the requirements of the switchgear or overload relay.

The rated motor currents are for standard 1500 r.p.m. 3-phase enclosed ventilated and totally enclosed fan-cooled motors.

D.O.L. starting: Maximum starting current 6 x rated motor current. Maximum starting time 5 s.

Y/D starting: Maximum starting current 2 x rated motor current. Maximum starting time 15 s.

Set overload relay in the phase lead to 0.58 x rated motor current.

Rated fuse currents for Y/D starting are also valid for 3-phase motors with slip-ring motors.

For higher rated currents, starting currents and/or longer starting times, larger fuses are required.

Table is valid for “slow” and/or “gL” fuses (DIN VDE 0636).

For NH fuses with aM characteristics, fuses = rated current is selected.
