MPCB stands for Motor Protection Circuit Breaker. It is a specialized device that provides protection against electrical faults in motor circuits such as short circuits, line-to-ground faults, and line-to-line faults. MPCBs combine the short-circuit and isolation functionality of the MCCB with the motor overcurrent protection of a traditional overload relay. They are widely used for both static and dynamic electrical equipment.

MPCBs are compact devices that can be mounted on DIN rails or directly to a panel. They typically have a handle or switch for manual ON/OFF control and an indicator to show the status of the device. Changan Electric can also provide motor protective circuit breakers with functions such as adjustable travel settings. Welcome to consult us for more product knowledge and technical support.
