Motor Protection Circuit Breaker (MPCB)
They are designed to withstand starting currents without interrupting the circuit.
0.1A to 100A | Up to 690V | 50/60Hz
High ambient Temperature @ 55 degree.
Standards :- IEC/EN 60947-4-1, CSA C22.2
Works at altitude up to 2000m
Every motor in your plant is an investment — and unplanned downtime is expensive. An MPCB (Motor Protection Circuit Breaker) provides complete motor protection in a single device, replacing the traditional MCB + overload relay combination. With built-in overload, short circuit, and phase failure protection, it safeguards your motors, reduces panel space, and eliminates the need for separate fuses — saving cost from day one.
