Miniature Circuit Breakers (MCBs)

Miniature circuit breakers (MCBs) ensure electrical safety in homes, offices, and other buildings as well as for industrial applications by protecting electrical installations against overloads and short circuits. Once a fault is detected, the miniature circuit breaker automatically switches off the electrical circuit to prevent damage to wires and to avoid the risk of fire. The miniature circuit breaker can be reset quickly and does not demand more maintenance costs. The working principle of the miniature circuit breaker is the respective principle of bimetal strips, which protect against overload current and solenoid short circuit current.
