MPCB Supplier & Manufacturer

An MPCB protects a motor circuit against overload, short circuit, and motor stall conditions, and provides a single-device alternative to separate fuses and thermal overload relays.

The adjustable current range is set to match the motor full-load current. Selection confirms the motor starting and running duty so the MPCB does not trip during normal starting surges.

An MPCB is designed for motor duty with a thermal overload curve that tolerates starting currents, whereas a standard MCB is intended for general circuit protection and is not matched to motor starting characteristics.

MPCBs are installed in motor starter panels, machine feeders, control cabinets, and motor control centres where motor overload and short-circuit protection are required.

Yes, an MPCB can combine overload and short-circuit protection in one unit. When combined with a contactor it forms a compact motor-starter assembly with reduced components and wiring.
