UL, CSA-1960V 50/60 Hz for one
minute between all electrically isolated
terminals. Comply with the 8mm
spacing and 3750V 50/60 Hz dielectric
requirements from hazardous voltage
to operator accessible surfaces and
between main circuits of adjacent
poles and from main circuit to auxiliary
circuits per Publications EN 60950 and
VDE 0805.

Trip Free
Trip Indication
Minimum of 100 Megohms@500VDC
50 operations @ 600% of rated current
5000 AMPs
10,000 “On-Off” Operations @ 6 per
minute; 6000 cycles with rated Current
and Voltage; 4000 cycles without
electrical load.
Trips 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.
