Motor Protection Circuit Breakers (MPCB)
About Motor Protection Circuit Breakers (MPCB)
Motor Protection Circuit Breakers (MPCBs) combine short-circuit and overload protection in a single DIN-rail or panel-mount device used ahead of or paired with a contactor to form a motor starter. Selection typically depends on motor FLC, voltage, HP/kW rating, trip class, and coordination type (Type 1 or Type 2).
