IAG/IUG/IEG/CEG Single Pole Circuit Breakers
IAG/IUG/IEG/CEG Magnetic
Circuit Breakers provide low-cost
power switching, reliable circuit protec-
tion and accurate circuit control for
equipment in the international
marketplace.
IEG models meet IEC spacing
requirements which is mandatory for
equipment that must comply with IEC
specifications 601 and 950 and VDE
specifications 0804 and 0805. In addi-
tion, they are UL Recognized, CSA
Certified, VDE Approved to VDE 0642
(EN60934) and CE Compliant. IAG
models are for those applications
where the unit’s inherent attributes are
desired, but compliance with the
various standards is not required.
Designed using the latest in sensitive
hydraulic magnetic technology, the
IAG/IUG/IEG/CEG line adapts itself
to many applications and environments.
They’re ideal for data processing and
business machines, medical instrumen-
tation, broadcast equipment, vending
and amusement machines, military
applications and wherever precision
operation is required. Temperature
differences which affect fuses and other
thermal devices are not a concern.
One important feature of this breaker
line is a “trip free” action, which means
the circuit will trip in the presence of
an overload even though the handle
is held in the ON position. The delay
mechanism senses the fault and the
contacts open.
The IAG/IUG/IEG/CEG is available
in a wide variety of configurations
including series, series with auxiliary
switch, shunt and relay with a choice
of delays and ratings in either DC,
50/60Hz or 400Hz versions. Handles
come in seven different colors and
international markings are standard.
Single or multi-pole versions are
available, with a variety of pole
arrangements to meet your specifica-
tions. Four pole models require a
double toggle handle. Units with a
handle per pole come in one through
six pole assemblies.

Tw o Pole Breakers
An assembly consisting of two single pole units, having their trip
mechanisms internally coupled and with a single toggle handle,
forms the IEG11 with quick-connect D.I.N.-style terminals.
Individual poles may differ in ratings, delays and internal
connections. An auxiliary switch may be included in either or
both poles, allowing you to mix SELV and hazardous voltages.
Rugged screw-type terminals can be provided, in which case
the designation would be IEG66. The IEGH offers a toggle
handle for each pole.
Three Pole and Four Pole Breakers
The three pole construction consists of three single pole units
assembled with an internal mechanical interlock which actuates
all units simultaneously. A single toggle handle operates all
three poles for quick and convenient control, or if preferred,
a handle per pole is available. The four pole construction consists
of four single pole units assembled with an internal mechanical
interlock which actuates all units simultaneously. A double
toggle handle operates all four poles. The individual poles need
not have identical characteristics and any series trip pole may
have an auxiliary switch. If screw-type terminals are required,
the breaker designation will be IEG666 for a three pole version
and IEG6666 for a four pole version.
Breaker poles are numbered consecutively when viewed from
the terminal side, with the ON position up, starting with Pole #1
on the left side and proceeding to the right.
Note: Tolerance ± .015 [.38] unless noted. Dimensions in brackets [ ] are millimeters.

Series with Auxiliary Switch
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.
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.
Auxiliary Switch (Applies to Series Trip Only)
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.
Auxiliary switch contacts actuate simultaneously with the main
breaker contacts, and will open regardless of whether the breaker
contacts are opened manually or electrically. For auxiliary switch
ratings below 6Vac or 5Vdc, an auxiliary switch with gold
contacts designated as REG is available. Gold contacts are
not recommended for load current above 100 milliamps.
Note:
A: Terminal protrusion dimensions are referenced from back mounting panel.
B: Main terminals are male push-on type .250 [6.35] wide x 0.31 [.79] thick
x .375 [9.53] long or 8-32 x .187 [4.75] screw type. Metric screw terminals
are M4 x 5mm (≤30A): M5 x 5mm screw type (>30A). On VDE approved builds
with screw terminals, external tooth lockwashers are supplied. On VDE approved
builds with push-on terminals a soldered connection is required above 25 amperes.

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, temperature, 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
By combining two electrically independent coils on a
common magnetic circuit, it is possible to provide contact
opening when either an over-current or trip voltage is
applied to the respective coils. One coil will be a current
trip coil with standard specifications. The second, or dual
coil, can be used to provide a control function permitting
contact opening from a remote interlock or other trans-
ducer functions. Standard coils are 6, 12, 24, 48, 120 and
240 volts. Tripping is instantaneous and must be removed
(usually self-interrupting) after trip.
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 configuration is becoming increasingly more
important for sensitive circuitry and denser packaging
in automation systems. Available in series, shunt or
relay configurations.

Inrush Pulse Tolerance
The following table provides a comparison of inrush
pulse tolerance with and without the inertial delay
feature for each of the 50/60Hz delays. Pulse tolerance
is defined as a single pulse of half sine wave peak
current amplitude of 8 milliseconds duration that will
not trip the circuit breaker. The table at left provides
a guide to determine if the inertia delay feature is
required. Consult factory for further assistance.

400Hz, DC, 50/60Hz Delay Curves (typ)
A choice of delays is offered for DC, 50/60Hz and 400Hz
applications. Delays 49, 59 and 69 provide fast acting,
instantaneous trip and are often used to protect sensitive
electronic equipment (not recommended where known inrush
exists). Delays 41, 51 and 61 have a short delay for general pur-
pose applications. Delays 42, 52 and 62 are long enough to start
certain types of motors and most transformer and capacitor
loads. Delays 43, 53 and 63 are long delays for special motor
applications at 400Hz, DC and 60Hz. CEG type units are only
available in 51, 52, 53 and 59 delay curves.

IAG / IUG / IEG / CEG DECISION TABLES
How to Order
The ordering code for IAG/IUG/IEG/CEG/IDG circuit
breakers may be determined by following the decision
steps in the tables shown here.
The coding given permits a self-assigning part number
but with certain limitations. Special applications may
require a factory-assigned part number. Typical examples
are units with mixed ratings, combinations of styles, or
constructions not listed in the third decision table. 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 provide cross reference, traceability and
manufacturing control.
When specifying a circuit breaker for AC motor start
or high inrush applications, the peak amplitude and surge
duration should be specified for factory assistance in
rating selection.
For example, the following is the code for a single
pole, IEG quick-connect type terminal, series unit with
auxiliary switch, designed for operation in a 50/60Hz
circuit. It has a short time delay, a rating of 20 amperes,
a black marked handle and is VDE approved.
To determine the ordering number for your particular
IAG/IUG/IEG/CEG 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.
Notes:
A. It is recommended that power leads be soldered to circuit
breakers having push-on type terminals for current trip ratings
above 20 amperes.
B. When “A” (metric thread mounting) is specified in the sixth
decision in combination with screw terminal option in the
second decision, metric screw terminals are supplied.
C. IEG, IEGH, IEGS, IEGHS, IEGX and IEGZX circuit breakers are
designed to meet 8mm creepage and clearance requirements for
installation Category III, Pollution Degree 3, Case A as measured
in IEC 664. Intended for use in equipment designed to comply
with IEC 601 and 950 and VDE 0804 and 0805.
