Electrical
Designed and tested in accordance with requirements of
specication MIL-PRF-55629 & MIL-STD-202 as follows:
Maximum Voltage 125VDC, 277VAC
Current Ratings Standard current coils: 100, 125,
150, 175, 225, 250 amps. 300,
350, 400, 500, 600, 700 amps
available as parallel pole
construction.
Auxiliary Switch Rating SPDT; 10.1 Amps @ 250VAC, 1.0
Amps @ 65VDC, 0.5 Amps @
80VDC 0.1 Amps @ 125VAC (with
gold contacts).
Insulation Resistance Minimum: 100 Megohms at 500
VDC
Dielectric Strength 1960 VAC, 50/60 Hz for one
minute between all electrically
isolated terminals, except 2500
VAC for one minute between
alarm/aux. switch and main
terminals with contacts in open
and closed position. F-Series
circuit breakers comply with the
8mm spacing & 3750VAC 50/60
Hz dielectric requirements from
hazardous voltage to operator
accessible surfaces, between
adjacent poles and from main
circuits to auxilary circuits per
Publications EN 60950 and VDE
0805.
Resistance, Impedance Values from Line to Load Terminal
- based on Series Trip Circuit
Breaker.
Endurance 4000 ON-OFF operations with rated
Current & Voltage & 4000
operations with no load (8000
operations total) @ 5 per minute.
Parallel Pole construction: 1000
operations with rated Current and
Voltage @ 5 per minute.
Trip Free All F-Series Circuit Breakers will trip
on overload, even when the
actuator is forcibly held in the ON
position.
Trip Indication The operating actuator moves
positively to the OFF position when
an overload causes the circuit
breaker to trip.
Number of Poles 1 - 3 Poles Note: Ratings over 250
Amps only available with parallel
pole.
Internal Circuit Cong. Series (with or without auxiliary
switch), Switch Only (with or without
auxiliary switch).
Available Accessories Factory installed: DC Current
Metering Shunt (25 mV @lr)
Weight Varies depending on construction.
Consult factory.
Standard Colors Housing - Black; Actuator- Black or
White with contrasting ON-OFF
legend.
Shock Withstands 100 Gs, 6ms, sawtooth
while carrying rated current per
Method 213, Test Condition “I”.
Instantaneous and ultra-short
curves tested @ 90% of rated
current.
Vibration Withstands 0.060” excursion from
10-55 Hz, and 10 Gs 55-500 Hz,
at rated current per Method 204C,
Test Condition A. Instantaneous
and ultrashort curves tested at 90%
of rated current.
Moisture Resistance Method 106D; ten 24-hour cycles @
+ 25°C to +65°C, 80-98% RH.56
