Bentec circuit breakers have been designed to meet stringent
conditions which meet salient specifications IS;8828 IEC Pub
898(95). Bentec MCB is a high fault capacity thermal magnetic
type of breaker, which protects against overload and short
circuits . Overload protection is achieved with a thermal
bimetal strip, which gets heated in case of overload that in
turn pushes the trip latch, which releases the contacts. In case
of short circuits, the high fault current energizes the magnetic
coil resulting in plunger striking the trip lever, which
ensures immediate release of the breaking mechanism.
