Manual motor starters, also known as motor protection circuit breakers (MPCBs) or manual motor protectors (MMPs), are electro-mechanical protection devices for the main circuit. They are mainly used to switch motors ON/OFF manually and to provide fuseless protection against short-circuit, overload and phase failures.
Manual motor starters switch and protect three-phase induction motors of up to 45kW at 400VAC, and loads with rated currents of up to 100A.
