Motor Protection Circuit Breaker|ELECTRECA

What is MPCB circuit breaker?
A motor protection circuit breaker, or MPCB, is a specialized electromechanical device that can be used with motor circuits of both 60 Hz and 50 Hz. It has several functions that allow it to provide a safe electrical supply for motors.
The MPCB can interrupt any electrical fault that is below its breaking capacity.

difference between MCCB and MPCB
An MPCB can protect a motor against overload and short circuit. MCCBs, when used in motor protection circuits can protect against short circuits only. Hence additional overload relay and contactor is required. A Motor can be directly turned ON and OFF manually using an MPCB, a contactor is optional.
