Designed and tested in accordance with requirements of
specication MIL-PRF-55629 & MIL-STD-202 as follows:
AC, 480 WYE/277 VAC, 50/60 Hz
(see Table A.)
UL489: AC,240 VAC. (Table D),
50/60 Hz, 125 VDC, UL 1077,
150 VDC, 277 VAC

0.250, 0.500, 0.750, 1.00, 2.50,
5.00, 7.50, 10.0, 15.0, 25.0, 30.0,

available, see Ordering Scheme.
DC - 6V, 12V; AC - 120V; other
ratings available, see Ordering
Scheme.
SPDT; 10.1 amps-250VAC, DC
Aux. Switch 1.0A, 65 VDC. 0.5A,
80VDC,1/4 HP, 125VAC,VDE & TUV
1.0 125 VAC.
Minimum of 100 Megohms at 500 VDC.
UL, CSA: 1960 V 50/60 Hz for one
minute between all electrically
isolated terminals. C-Series
Circuit Breakers comply with the
8mm spacing and 3750V 50/60
Hz dielectric requirements from
hazardous voltage to operator
accessible surfaces, between
adjacent poles and from main
circuits to auxiliary circuits per
Publications EN 60950 and VDE
0805.
Values from Line to Load Terminal
based on Series Trip Circuit
Breaker.
10,000 ON-OFF operations @ 6 per
minute; with rated current & voltage
All C-Series circuit breakers will trip
on overload, even when actuator is
forcibly held in the ON position.
The operating actuator moves
positively to the OFF position when
an overload causes the breaker to
trip. With mid-trip, handle moves to
the mid position on electrical trip
of the circuit breaker. With mid trip
handle with alarm switch, handle
moves to the mid position and
the alarm switch actuates when
the circuit breaker is electrically
tripped.
1-6 poles ≤ 50A; 1-4 poles @ 51-
70A; 1-2 poles 71-100A. UL489
Handle: 1 pole ≤ 100A, 2 pole ≤
50A; Rocker: 1 pole ≤ 100A.
Series (with or without auxiliary
switch, mid trip & mid trip with
alarm switch) Shunt & Relay with
current or voltage trip coils, Dual
Coil, Switch Only (with or without
aux. switch). UL489: Series (with or
without auxiliary switch, mid-trip &
mid-trip with alarm switch).
Approx.112 grams/pole ( 3.95 oz).
Housing: Black
Withstands 100 Gs, 6ms sawtooth
while carrying rated current per
Method 213, Test Condition “I”.
Instantaneous and ultrashort curves
tested @ 90% of rated current.
Withstands 0.060” excursion from
10-55 Hz & 10 Gs 55-500 Hz, @
rated current per Method 204C,
Test Cond. A. Instantaneous &
ultrashort curves tested @ 90% of
rated current.
Method 106D, i.e., ten 24-hour
cycles @ +25°C to +65°C, 80-98%
RH.
Method 101, Condition A (90-95%
RH @ 5% NaCl Solution, 96 hrs).
Method 107D, Condition A (ve
cycles @ -55°C to +25°C to +85°C
to +25°C).
