C-Series General Specifications
Designed for those applications requiring higher amperage and volt-
age handling capability in a compact design. Available with
American Standard or Metric Threaded Stud terminals, or Saddle
Clamp screw terminals. Available with optional mid-trip handle style
actuator, solid color rocker actuators and Visi-rocker two color actu-
ators. Visi-rocker can be specified to indicate either the ON or
TRIPPED/OFF mode. Rockerguard and Push-To-Reset bezel help
prevent inadvertent actuation.
The C-Series UL489 breakers employ a unique arc chute design
which results in obtaining higher interrupting capacities, up to
50,000 amps. Thermoset glass filled polyester half shell construc-
tion for increased mechanical & electrical strength; Wiping Contacts
- Mechanical linkage with two-step actuation – cleans contacts, pro-
vides high, positive contact pressure & longer contact life;
1-6 poles, 0.02 - 100 amps, up to 480 VAC or 80 VDC, UL489 up
to 240 VAC or 125 VDC, with choice of time delays and actuator
colors.

Breakers comply with the 8mm
spacing and 3750V 50/60 Hz dielec-
tric requirements from hazardous
voltage to operator accessible sur-
faces, between adjacent poles and
from main circuits to auxiliary circuits

Endurance
Trip Free
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 posi-
tively 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.
