General information

Smooth and safe operation of this switching device requires proper transport and

storage, professional installation and assembly, as well as careful operation and

maintenance.

The operating instructions are an integral part of the switching device and contain

all information for commissioning and use.

The basic version and all listed configurations of the vacuum contactors 3TM are

type-tested devices as per IEC 62271-1 (see also “Standards”, on page 10)

WARNING

Dangerous electrical voltage and mechanical movements

When electrical devices are operated, certain parts are inevitably live under

dangerous voltage, and mechanical parts may move very quickly, also

when remotely controlled.

If the warning notices are not observed, serious injury or material damage may

be the result.

Only personnel with the relevant qualifications may work on or in the vicinity of

this device. These personnel must be familiar with all warnings and servicing ac-

tivities specified in these operating instructions.

CAUTION

Material damage caused by electrostatic discharge to the electronic con-

troller

Electrostatic discharge can cause material damage to the electronic controller

and restrict its functionality.

To prevent damage to electronic components, discharge any existing electrostat-

ic charges on hands or tools by touching grounded surfaces prior to touching

electronic components and before removing the connector plugs.

Note

In the event of subsequent attachments or fittings, e. g. locking parts in connec-

tion with switchgear, ensure that

• fast moving parts are not additionally loaded with masses or forces and

• additional parts have sufficient clearance, in particular, from moving and live

parts.

If the vacuum contactor is to be equipped with additional functions by the custom-

er, we recommend consulting the factory, since tried and tested solutions are fre-

quently available.

Installation position

Observe the distances as per IEC 60071 insulation coordination or comply with the

required air distances according to the national operational requirements.

- Front side: High-voltage section with protection class IP00.

- Rear side: Low-voltage section with protection class IP20.

Installation position The vacuum contactor 3TM can be installed in four positions.

1) Wall mounting, vertical

2) Supine position, horizontal

3) Wall mounting, vertical, rotated 180°

4) Suspended, with reduced parameters (after consultation with manufacturer)

*) Observe distance to high-voltage and grounded components!

Fig. 5 Installation position

High-voltage section The high-voltage section consists of individual, autonomous pole shells, which can

receive the correspondingly dimensioned vacuum interrupters. This makes variable

distances between the pole centres possible (120 mm and 150 mm).

Solenoid actuator The vacuum interrupters are actuated by a common solenoid actuator. This solenoid

actuator has a very low holding capacity in continuous operation. The vacuum inter-

rupters work synchronously in the same direction.

The solenoid actuator and the shunt release of the vacuum contactor 3TM can be

actuated with AC or DC.

Vacuum contactors 3TM work according to a defined closing and opening time,

which can be configured and extended by an additional closing and opening delay.

Both delay values are independent of each other and are added to the closing and

opening times.

Electronic controller The electronic controller controls the supply of energy to the solenoid actuator on

closing. The closing current is controlled to a specified level. The current is switched

to the holding current after a specified time. The holding current reduces the vacuum

contactor’s energy supply during operation.

The voltage supply of the magnetic unlatching is not affected. The customer is to

deal with the signal control. The maximum signal duration is to be observed, since

the shunt release solenoid only has a limited continuous current strength of 500 ms.

The inrush current (peak) is dependent on the control voltage.

Control voltage terminals The electronic controller has terminals for the following:

• the control voltage A1/A2,

as well as independent thereof

• the supply voltage for the magnetic unlatching E1/E2 (optional).

Fig. 6 Terminals A1/A2 and optionally E1/E2 of the electronic controller

The electronic controller also allows the configuration of additional closing and open-

ing delays. If no configuration is selected, only the natural closing and opening time

of the switching device is active. Configuration is done via a 6-pin DIP switch S2 on

the electronics assembly (matrix, see Chapter “Configuring the controller”, p. 48).

Auxiliary switch The auxiliary switches are mounted on the side of the operating mechanism box and

are not wired. The wiring is carried out on the customer’s premises using screw ter-

minals.

Mechanical closing

latching

(Applies only to vacuum contactors with closing latching)

When the vacuum contactor is closed, the mechanical closing latching is activated.

The solenoid actuator is held and automatically separated from the voltage supply

once the latching position is reached.

Switching in the de-energised holding mode (control voltage circuit A1/A2) is carried

out automatically via the electronic controller.

Electromagnetic unlatch-

ing and manual unlatching

Unlatching is done via:

• Electromagnetic unlatching, remote-controlled

• Manual unlatching via push rod or draw bar.

The remote tripping is carried out via the electromagnetic shunt release Y1 (9). If

manual unlatching (emergency-stop) via the push rod or draw bar is not available,

the shunt release Y1 can be carefully manually actuated from the rear side of the

vacuum contactor in a de-energised state and for test purposes (see details in

Fig. 8).

Manually operated unlatching (emergency-stop) is performed with a push rod or

draw bar (12, 15) with approx. 30 N. The customer is to mount M4 threaded rods for

the push rod or draw bar with fitting end pieces or other suitable terminators. Tight-

ening torque 3 ±0.5 Nm.

Subsequent ordering If no latching or unlatching is available but is planned for backfit, the following mod-

ules can be subsequently ordered and mounted:

• Mechanical closing latching with shunt release Y1

• Manually operated unlatching mechanical system (emergency-stop) with push

rod or draw bar

See chapter “Mounting the mechanical closing latching (optional) and manual

unlatching (optional)”, p. 35.

A description of the installation is only supplied with the operating instructions of the

retrofit kit.

Installation altitudes

As standard, 3TM vacuum contactors can be used at -1250 m to +2000 m. For high-

er operation heights, a configuration from 2000 m to 5000 m can be ordered.

Insulation capacity The insulation capacity of insulation in air declines with rising altitude due to the low-

er air density. As per IEC 62271-102, the rated lightning impulse voltage values giv-

en in Fig. 11 are valid up to an installation altitude of 1000 m above sea level.

Above an altitude of 1000 m, the insulation level must be corrected as shown in

Fig. 16:

Note

The installation altitude for the vacuum contactor is set at the factory according

to the ordering option.

Installation

DANGER

Risk of injury!

• Do not touch live parts!

• When work is performed on the switchgear, the switchgear must be de-ener-

gised and earthed!

• The work described in the following sections must only be performed when

the switchgear has been de-energised:

- Take safety measures to prevent it from being switched back on!

- Observe industrial safety regulations!

- Ensure that the vacuum contactor is mounted and commissioned only by

qualified personnel who are familiar with the operating instructions and

observe the warning notices.

CAUTION

Inadequate ventilation leads to material damage.

The customer is to ensure there is adequate ventilation in the installation space

or in the switch cabinet (see “Installation position”, p. 15).

Note

Transporting the vacuum contactor

Transporting the vacuum contactor by holding and lifting the auxiliary switches on

the sides leads to material damage.

Only transport the vacuum contactor by holding it under the operating mechanism

box, the base plate, or the pole shells (see “Transport to the installation site”,

Fig. 1).

Note

Attaching the vacuum contactor

Attaching the vacuum contactor with shear, tensile, or compressive stresses can

lead to material damage.

Attach the vacuum contactor by the specified mounting points without shear, ten-

sile, or compressive stresses.

Installation

Operation

Commissioning

Dielectric tests To test the vacuum contactor in a state without supply and control voltage, it is nec-

essary to short-circuit and earth the terminals for supply and control voltage A1/A2

and, if applicable, E1/E2 for the supply voltage for magnetic unlatching.

Subsequently the following tests can be performed:

• Dielectric test of the main circuit as per DIN EN 62271-1 (Chapter 7.1.) and

• Dielectric test of the auxiliary and control circuits as per DIN EN 62271-1 (Chap-

ter 7.2.4.).

Before commissioning, check the following points to ensure that the vacuum contac-

tor is functioning faultlessly.

Continued on the next page

DANGER

Danger to life due to electric shock!

Electric shock can result in death, serious injury, or considerable material dam-

age.

• Do not touch live parts!

• Ensure that the vacuum contactor is operated only by qualified personnel

who are familiar with the operating instructions and observe the warning

notices!

• Check through all of the items on the checklist and ensure correct functioning

before commissioning!

Checklist Notes

Does the information on the rating plate match the order data (see p. 17)?

Ensure correct operating voltage.

Check the control feed voltage and the performance data of the low-volt-

age network are correct.

If necessary, clean the vacuum contactor (details on this in section

“Cleaning” on p. 45).

Check that a stable supply voltage is applied with a short-time load

exceeding 1.7 kW, otherwise the switching device will not reach the clos-

ing position or reach it with a delay.

If necessary, check the functionality of the manual unlatching (EMER-

GENCY STOP) in conjunction with the switch cabinet door.

Check that screw connections are tightened securely.

Check the plug connections for a firm seat.

Check the functioning of the auxiliary switches.

If necessary, check and adjust the customer's devices.

If the DIP switch setting has been changed by the customer:

Check the correct setting of the DIP switch on the electronic controller

(see p. 48).

Check changed MLFB entries on the rating plate.

Operation

42 9229 0090 176 0A

Troubleshooting

1) Complete vacuum contactor

First closing operation

If all functions have been checked and are OK, switch on the high voltage while ob-

serving all of the safety regulations and operational requirements.

Checklist Notes

Check the unlatching. If manual unlatching (emergency-stop) via the push

rod or draw bar is not available, the shunt release (-Y1) can be manually

actuated in a de-energised state and for test purposes (see Fig. 8 on

p. 16).

Test the electric switching repeatedly before the vacuum contactor is put

into operation in the network.

WARNING

Do not commission the vacuum contactor if there are malfunctions.

If the malfunctions or damage cannot be remedied, contact a sales representative

or Siemens Service and, if necessary, send back the vacuum contactor in the

original packaging.

Incident Troubleshooting

Vacuum contactor does not

respond

• Check the DIP switch S2 position and reset if necessary (see matrix Fig. 52).

Closing is blocked • Send it back to the manufacturer1).

Failure of the control voltage

• Check the connectors on the electronic controller for a firm seat.

• Check the cable connection to the connectors.

• If a new vacuum contactor is installed, use only the connectors provided in

the accessory pack (see p. 36).

Defective shunt release • Order a spare part and mount according to the supplied instructions.

Vacuum contactor does not

return to the starting position

or the initial state

• Inspect the contact welding and remedy by means of no-load switchings.

• For existing closing latching, actuate the manual unlatching (no-load switch-

ing permissible).

Vacuum contactor does not

latch • Send it back to the manufacturer1).

Manual unlatching is blocked • Check that the unlatching mechanism is attached to the coupling point and

reattach with max. 4 Nm. While doing so, prevent the threaded rod from twist-

ing.

Maintenance
Maintenance and servicing
Inspections The following work is to be carried out as part of the regular inspections:
• Visual inspections during storage, see “Storage” on p. 7
• Visual inspections during operation
• Screws and terminals are firmly attached
• Earthing connection firmly established and not damaged
• Labelling is clearly legible
• Insulation capacity not hampered by deposits, see “Cleaning” on p. 45
• Check the limit dimension of switching stroke of the vacuum interrupters,
depending on the mechanical and electrical strain or switching frequency, every
100,000 switchings or once a year. See “Checking the switching stroke of vac-
uum interrupters” on p.  43
• Regular function check of closing latching and then unlatching with manual trip,
see “Mechanical closing latching”, on p. 16
• Measurement of conductance of auxiliary switch contacts.
Checking the switching
stroke of vacuum
interrupters
Reliable switching of the 3TM vacuum contactor is only ensured if the switching
stroke of the vacuum interrupters is not below the minimum of 3.5 mm and does not
exceed the maximum of 7.5 mm.
The switching stroke can vary depending on current, elapsed service life, and
switching frequency. If the value goes below the limit, arcing between the contacts
in the vacuum interrupter can negatively affect opening.
Correct functioning of the bellows for the vacuum interrupters can be compromised
if the limit is violated.
The switching stroke must be regularly checked. If the limit is reached, the switching
stroke can be readjusted once.
If the limit is then exceeded again, the vacuum contactor must be replaced.
If the specified limits for mechanical or electrical service life are reached, the vacu-
um contactor must be replaced and readjustment is not permissible.
  DANGER
Risk of injury!
Working on the opened and closed vacuum contactor can lead to fatal injuries.
• Before beginning maintenance work, note the 5 safety rules for high-voltage
equipment specified in EN 50110-1, namely:
- Isolate from the power supply
- Secure against reclosing
- Verify that the equipment has been de-energised
- Earth and short-circuit
- Cover or cordon off neighbouring live parts
• Open the vacuum contactor by hand and operate the mechanical unlatching if
necessary. This ensures that the vacuum contactor is open.
• The vacuum contactor is to be taken out of the system/switch cabinet for
maintenance work.

Replacing the electronic controller

If the electronic controller is to be replaced, then remove and mount according to the

supplied assembly drawing.

Setting the electronic

controller

If necessary: Using the DIP switches S2 (26) and the set-up matrix, have the cus-

tomer adjust the settings on the electronic controller (see Fig. 52, p. 48).

CAUTION

Material damage caused by electrostatic discharge to the electronic con-

troller

Electrostatic discharge can cause material damage to the electronic controller

and restrict its functionality.

To prevent damage to electronic components, discharge any existing electrostat-

ic charges on hands or tools by touching grounded surfaces prior to touching

electronic components and before removing the connector plugs.

Note

Store all disassembled screws, washers, and nuts safely for reuse.

Configuring the controller

Observe the following when reordering the switching device:

If the factory-supplied configuration is changed by the customer, the MLFB on the

rating plate is invalid and the warranty is void. Despite this, the MLFB on the rating

plate must then be changed. Line g, s to v, see “Example - rating plate for vacuum

contactor 3TM”, page 17, Fig. 9.

1) Average values under normal conditions. Deviations possible under different ambient conditions.

2) If closing latching is available, the opening delay is disabled and DIP switch S2 in 3 and 4 is to

be left OPEN
