IAL/IUL/IEL/IDL/LEL SPECIFICATIONS
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 the breaker on.
Trip Indication
The operating handle moves positively to the OFF or mid-trip
position on electrical overload.
Ambient Operation
IAL/IUL/IEL protectors operate in temperatures between –40°C
to +85°C.
Insulation Resistance
Not less than 100 megohms at 500 volts DC.
Dielectric Strength
IAL/IUL/IEL protectors withstand 3750Vac (1250Vac for LEL),
60Hz for 60 seconds between all electrically isolated terminals
except auxiliary switch terminals shall withstand 600Vac, 60Hz
for REG and REC types. Four terminal dual coil and relay con-
struction (not offered in the LEL) will withstand 1500Vac.
Endurance
Operating as a switch, the operating life exceeds 10,000 oper-
ations, 6000 at rated load, 4000 without load, at a rate of 6 per
minute.
Electrical Characteristics
.050-100 amperes 80Vdc, 240Vac Max., 240/415Vac at 50
amperes Max., 50/60Hz and 400Hz. Consult factory for specific
product ratings. Units rated for 240/415Vac and above 50
amperes are not suitable for across-the-line motor starting.
Poles
One through six poles available.
Construction
Series, shunt, relay dual coil and series with auxiliary switch
available in various delays and combinations.
Auxiliary Switch
When supplied shall be S.P.D.T. configuration. Non VDE
approved switches have a maximum UL rating of 10.0
amperes, 250 volts, 60Hz; 3.0 amperes, 50 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 (REC type); or 0.1 amperes, 125 volts,
60Hz (REG; type). The maximum VDE ratings are 1.0 amperes, 125
volts, 60Hz (REC type); 0.1 amperes, 125 volts, 60Hz (REG type).
Salt Spray (Corrosion)
Meet the requirements of MIL-PRF-55629 when tested in
accordance with Method 101 of MIL-STD-202.
IAL/IUL/IEL/LEL Series - Specifications
moisture Resistance
Meet all the requirements of MIL-PRF-55629 when tested in
accordance with Method 106 of MIL-STD-202.
Shock
Circuit protectors shall not trip when tested per MIL-STD-202,
Method 213, Test Condition I with 100% rated current applied
to delayed units and 80% rated current to instantaneous units.
Vibration
Circuit protectors 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.
UL-1500 (marine Ignition Protected)
The IDL/IDLH is approved for Marine Ignition Protection (series
configuration only), covering ignition protected circuit break-
ers. This specification requires devices to be used in
accordance with the requirementsof U.S. Coast Guard and Fire
Protection Standard for Pleasure and Commercial Motor Craft,
ANSI/MFPA #302.
Where applicable, mechanical support must be provide to the terminals when
applying torque
