IAG / IUG / IEG / CEG SPECIFICATIONS
IAG/IUG/IEG/CEG Specifications
122
Trip Free
Will trip open on overload, even when forcibly held in the ON
position. This prevents the operator from damaging the circuit
by holding on the breaker.
Tr ip Indication
The operating handle moves positively to the OFF position
on overload.
Ambient Operation
IAG/IUG/IEG/CEG breakers operate in temperatures between
-40° C to +85° C.
Insulation Resistance
Not less than 100 megohms at 500 volts DC.
Dielectric Strength
IAG/IUG/IEG/CEG breakers withstand 3750Vac, 60Hz for 60 sec-
onds between all electrically isolated terminals, except auxiliary
switch terminals shall withstand 600Vac, 60Hz for REG and REC
types. Four terminal dual coil and relay construction (not offered
in the IEG) will withstand 1500Vac.
Endurance
Operating as a switch, the operating life exceeds 10,000 operations
at a rate of 6 per minute when tested as follows: 6000 OPS @ rated
current plus 4000 OPS @ at no load.
Electrical Characteristics
.050-50 amperes; 80Vdc Max., 240Vac Max., 50/60Hz and .050-30
amperes: 250Vac Max., 400Hz.
Units above 30 amps are not suitable for across-the-line
motor starting.
Auxiliary Switch
When supplied shall be SPDT configuration. Non VDE approved
switches have a maximum UL rating of 10.0 amperes, 250 volts,
60Hz; 3.0 amperes, 50 volts DC, 1 amperes, 80 volts DC (REC)
type or 0.1 amperes, 125 volts, 60Hz. (REG type).
VDE approved switches have a maximum UL rating of 10.0
amperes, 250 volts, 60Hz, 1 amperes, 80 volts DC (REG type); or
0.1 amperes, 125 volts, 60Hz (REG type); or 0.1 amperes,
125 volts, 60Hz (REG type).
Moisture Resistance
Meets all the requirements of MIL-PRF-55629 when tested in
accordance with Method 106 of MIL-STD-202.
Salt Spray (Corrosion)
Meets the requirements of MIL-PRF-55629 when tested in
accordance with Method 101 of MIL-STD-202.
Shock
Circuit breakers shall not trip when tested per MIL-STD-202,
Method 213, Test Condition I with 100% rated current applied to
delayed units, except 90% current in plane 4 (i.e., handle down).
Instantaneous units shall have 80% rated current applied in
all planes.
Vibration
Circuit breaker shall not trip when vibrated per MIL-STD-202,
Method 204, Test Condition A with 100% rated current applied
to delayed units and 80% rated current to instantaneous units.
Construction
Series, shunt, relay and series with auxiliary switch available in
various delays and combinations.
VDE Approval
IEG is VDE approved under VDE 0642 (EN60934). The IEG has
8mm creepage and clearance between the main circuit and the
following areas:
A. Operator accessible area around the handle.
B. The mounting inserts or brackets.
C. The auxiliary switch circuit.
D. Between poles.
Care must be taken to maintain spacings at the terminals when
wired. The VDE approval for standard terminals is not for use
with bare wire. A crimp type lug is required.
In addition, all VDE approved units will be in compliance
with specific CE Directives. These units will be marked as
CE Compliant.
UL1500 Recognized
IDG/IDGH is approved for Marine Ignition Protection rated at
65Vdc or 125/250Vac to 30 amperes with 1000 amperes maximum
interrupt capacity or 32Vdc with 3000 amperes maximum inter-
rupt capacity.
UL489A Listed
The CEG is dimensionally the same as the popular IEG, but
provides UL listing to UL489A. Available in one to three poles,
in series, series with auxiliary switch, shunt, dual coil and voltage
trip configurations. As a circuit breaker, the CEG provides commu-
nication equipment manufacturers with a UL listed circuit breaker
in a very compact package that meets the stringent environmental
requirements of today’s marketplace. This makes the CEG ideal for
switching, transmission and wireless applications.
