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.
