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.
