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 (five

cycles @ -55°C to +25°C to +85°C

to +25°C).
