INTRODUCTION
The 209, E-Frame circuit breaker combines power switching with
accurate, reliable circuit protection in a compact single or multi-
pole unit. The unit is ideal for branch circuit applications such as
EDP, air conditioners, panel boards and lighting controls.
The 209 is actually a family of circuit breakers available in one
through six pole assemblies with a variety of configurations
and terminal styles to meet your application needs. First in this
family is the 209, a general purpose E-Frame circuit breaker
which complies with UL Standard 489. Other members of the
family include the 219, for manual controller applications,
which complies to UL Standard 508, the 229, for supplementary
protectors applications, which complies to UL Standard 1077,
and the 299, a Special Construction version.
Utilizing the hydraulic-magnetic principle, the 209 family adapts
itself to local applications and environments. Temperature
conditions, which affect fuses and other thermal devices, are
not a concern. The magnetic /ampere turn principle minimizes
nuisance tripping due to temperature variations.
Inrush currents, due to ferroresonant transformers, lamps
and capacitive filters, are now becoming more significant.
Recognizing the need for this type of protection, Airpax offers the
unique inertial delay which is standard for all 50/60Hz time delay
units, but may be deleted where inrush is not a problem. No extra
cost or special order is required.
The 209 family of circuit breakers withstands high pulses
without tripping or affecting normal delay curves. This
performance, however, does not derate or sacrifice protection.

209/219/229/249/279 Series - 249 Power Selector Breaker System
167
The 249 Power Selector Breaker System combines
magnetic-hydraulic branch circuit overload protection
and a power system selector switch in one device.
The 249 is designed to allow selection of any one of
two, three or four independent power systems. This is
accomplished with fool-proof sliding-gate handle
covers. The number of sliding covers is one less than
the number of power systems. With this arrangement,
it is impossible to switch “ON” more than one power
system at a time.
Since the 249 Power Selector Breaker System is listed
as a Branch Circuit Breaker per UL 489 and power
switching is accomplished by UL listed breakers, it is
usually not necessary to include additional branch
service protection.
Standard options available include terminals for front
or back connections, choice of trip time delay, current
ratings to 100 amperes and single or multi-pole
sections.
Trip Time Delay
Three inverse time delays are available to permit close coor-
dination with various loads. Delays 51 and 61 are short
delays for electronic loads. Delays 52 and 62 are medium
delays for mixed loads. Delays 53 and 63 are long delays for
motor loads.
Current and Voltage Ratings
Single pole and multi-pole breaker ratings are available up
to 100 amperes, 240Vac or 125Vdc. The special configuration
for Marine use has a 120V/240Vac rating for current rating
up to 100 amperes.

Standard circuit breaker terminal and configurations are
shown. For other types, consult factory.

Common-Trip Construction
All multi-pole protectors contain an internal trip bar which
opens all poles in the event of an overload in any pole.
Handles are ganged externally for simultaneous actuation.
Individual poles may differ in ratings, delays and
configurations, providing an almost limitless number of
combinations.
Multi-pole protectors (up to 6 poles) easily satisfy special
modern day circuitry. Series, shunt, relay and auxiliary switch
construction add to the versatility of design engineering.
Airpax’s sales engineering force is ready to assist in proper
unit selection, both for equipment protection and economical
design.
Three Phase, Four Pole Includes Control Protector
Remote shutdown of equipment is sometimes necessary or
desirable in today’s sophisticated equipment. The 219 four
pole assembly fills this need for three phase operation. Three
of the four poles are designed for the circuit’s proper
operating current and over-current protection. The fourth
pole may be designed for instantaneous tripping by logic
circuitry, interlocks or from a manual remote site or control.
The control power required would be quite low, with voltages
from 5 to 125Vdc, or 5 to 240Vac available. The fourth pole
construction is optional. It may be either series, shunt or
relay, depending on the application required. When
specifying, both the minimum trip voltage and Hz are required.
Factory consultation is readily available.

Series Trip
The most popular configuration for magnetic protectors is
the series trip, where the sensing coil and contacts are in
series with the load being protected. The handle position
conveniently indicates circuit status. In addition to
providing conventional overcurrent protection, it’s
simultaneously used as an ON-OFF switch.
Auxiliary Switch
This is furnished as an integral part of a series pole in
single or multi-pole assemblies. Isolated electrically from
the protector’s circuit, the switch works in unison with the
power contacts and provides indication at a remote
location of the protector’s ON-OFF status.

Relay Trip
This permits the overload sensing coil to be placed in a circuit
which is electrically isolated from the trip contacts. The coil
may be actuated by sensors monitoring pressure, flow, tem-
perature, speed, etc. Other typical applications include
crowbar, interlock and emergency/rapid shutdown circuitry.
Trip may be accomplished by voltage or current, which must
be removed after trip.
Dual Coil
Providing for both a voltage trip and a current trip function in
a magnetic circuit protector is common practice. These two
coil protectors provide remote or automatic opening of one or
more circuits with a low level signal.
The voltage coil will trip the protector instantaneously while
the current coil provides normal inverse time delays. The volt-
age coil is not rated for continuous duty and therefore, the
voltage must be removed when the breaker trips.
Since both coils are housed within the same pole, the space
savings are substantial.
This option is not available with 64, 65 or 66 delays.
Shunt Trip
The shunt trip is designed for controlling two separate loads with
one assembly. The control is established by providing overload
protection for the critical load. When the current through this
load becomes excessive and reaches the trip point, the protector
will open and remove power from both loads simultaneously. The
total current rating of both loads must not exceed the maximum
contact rating.
Voltage Trip
Sometimes called “dump circuits” or “panic trip circuits,”
these units make it possible to open main power contacts with
lower power inputs from one or more sources. This configura-
tion is becoming increasingly more important for sensitive
circuitry and denser packaging in automation systems.
Available in series, shunt or relay configurations.

209/219/229/249/279
50/60Hz Delay Curves (typ)
A choice of delays is offered for 50/60Hz applications.
Delay 61 is a short delay for general purpose
applications. Delay 62 is long enough to start certain
types of motors and most transformer and capacitor
loads.
Delay 63 is a long delay for special motor applications.
Delays 64, 65 and 66 are the latest 50/60Hz delays with
short, medium and long trip times respectively. The
patented breaker design provides both increased
tolerance to high inrush induced nuisance tripping and
longer trip times at 600 percent. These delays are
ideally suited for applications where thermal devices
are presently used, such as motor protection or where
short duration, high inrush currents are experienced.
As shown in a typical motor start-up curve, the delay 66
will provide locked rotor and overload protection.
Nuisance tripping is avoided, since acceptable short
periods of overload will not trip the breaker.
All trip curves and trip currents are specified with the
breaker mounted in the normal vertical position at
ambient temperature of +25°C. For test and
measurement purposes, the breakers should not carry
current prior to application of overload for calibration
test. For other than vertical mount position, consult
factory.

209/219/229 SPECIFICATIONS
Trip Free
Will trip open on overload, even when forcibly held on. This
prevents the operator from damaging the circuit by holding
the handle in the ON position.
Trip Indication
The operating handle moves positively to the OFF position
on overload.
Environmental Specifications
Moisture and fungus resistance is provided by the use of
moisture resistant finishes. Special springs and treatment
for all ferrous parts eliminate inherent moisture-related
problems. The use of fungi inert cases and handles avoids
fungus-related problems.

How to Order
The ordering code for 209, E-Frame Circuit Breakers may be
determined by following the steps in the decision tables
shown here.
The coding given permits a self-assigning part number for
standard configurations. Factory part numbers are assigned
to units with mixed ratings, combinations of styles or con-
struction not listed in the Third Decision Table, etc. With
these, it is suggested that order entry be by description and/
or drawings, and a part number will be established.
Additionally, it is standard policy to establish a factory-
assigned part number whenever a descriptive drawing
exists to insure cross reference, traceability and manufac-
turing control.
When specifying a breaker for AC motor start or high inrush
applications, the peak amplitude and surge duration should
be specified for factory assistance in rating selection. 209
and 239 are UL listed circuit breakers under file no. E53739
per UL 489.
279 is a UL listed under file no. E192808 per UL 489A.
219 is a UL recognized “Manual Motor Controller” under file
no. E41607 per UL 508.
229 is a UL recognized supplementary protector under file
no. E66410 per UL 1077.
For example, the following is the code for a single pole
breaker with series trip, 50/60Hz, medium inertial delay,
120/240Vac maximum voltage ratings, solderless connector
with mounting foot added to the line side of the breaker to
facilitate back panel mounting and a current rating of 10.0
amperes.
To determine the ordering number of your particular 209 unit,
simply follow the steps shown. You may use this number to
place an order or as a reference for further questions you may
have.

How to Order
To evolve a convenient ordering system for most applications,
the following code has been developed. If a system is required
which is not covered below, please consult factory or describe
in detail. The number shown as an example describes a 120 volt,
three section system, such as may be used on a boat with a port
and starboard shore power receptacle and an AC generator. The
breaker rating for the shore power is 30 amperes and for the
generator 20 amperes in this example. 1/4 -20 screw type
terminals and a medium time delay are specified.
