Dielectric Strength
UL, CSA-1500 V 50/60 Hz for one
minute between all electrically
isolated terminals. B-Series circuit
breakers comply with the 8mm
spacing and 3750V 50/60 Hz
dielectric requirements from

All B-Series Circuit Breakers will
trip on overload, even when Handle
is forcibly held in the ON position.
The operating Handle moves
positively to the OFF position when
an overload causes the breaker to
trip.
