With System pro M compact® ABB offers an extra-wide and complete range of miniature circuit breakers to cover most applications and markets. Warranting reliability and safety for people and assets, MCBs are equipped with two tripping mechanisms: the delayed thermal tripping mechanism for overload protection and the magnetic tripping mechanism for short circuit protection. 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. 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.
