INTRODUCTION
The Airpax™ IAG/IUG/IEG/CEG/LEG magnetic circuit protectors
provide low-cost power switching, reliable circuit protection
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 addition, they are
UL Recognized as supplementary protectors per UL STD. 1077,
CSA Certified as supplementary protectors per CSA C22.2–No.
235, VDE Approved to VDE 0642 (EN60934), CCC Approved 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/LEG line adapts itself to many
applications and environments. They’re ideal for data processing
and business machines, medical instrumentation, 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 protector 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/LEG 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 specifications. Four pole models require a double
toggle handle. Units with a handle per pole come in one through
six pole assemblies.

MULTI-POLE CIRCUIT PROTECTORS
(IAG/IUG/IEG/CEG/LEG)
Two Pole Protectors
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. LEG type units are avavailable only in one or two pole
configurations.
Three Pole and Four Pole Protectors
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.
Protector 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.

The Snap-In version of the IEG brings mounting simplification
and international spacing together in a package that is
aesthetically enhanced. The IEGS securely snaps into a
rectangular cut-out, eliminating the need for panel mounting
hardware and the associated costs. The face plate of the IEGS
is a clean, black matte and it satisfies the increasing demand
for front panel components that are designed with ergonomic
considerations.
The IEGS is offered in either flush or beveled versions, in 1, 2, 3
or 4 pole packages, and with a handle per pole or per unit.
The IEGS is UL Recognized, CSA Certified and VDE approved.

CONFIGURATIONS
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 protector contacts, and will open regardless of
whether the protector 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 transducer 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.

IAG/IUG/IEG/CEG DECISION TABLES
The ordering code for IAG/IUG/IEG/CEG/IDG circuit
protectors 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 protector 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
protectors 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 protectors 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.

LEG DECISION TABLES
The ordering code for LEG 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, LEG screw 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 LEG
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. 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.
B. LEG, LEGH, LEGS, LEGHS, LEGZX and LEGBX 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.
