A Motor Protection Circuit Breaker (MPCB) is a specialised device designed to protect electric motors from overload, short circuits, and phase failures. It combines the functions of a circuit breaker and an overload relay in one compact unit, ensuring reliable motor operation and safety. MPCBs are commonly used in industrial and commercial environments where electric motors run critical equipment. They provide manual switching, trip-free operation, and adjustable thermal and magnetic protection tailored to motor specifications. Unlike standard MCBs, MPCBs are engineered specifically for motor loads, offering precise fault detection and quick disconnection to prevent damage. With built-in reset options and compatibility with contactors and starters, MPCBs are essential for efficient and safe motor control systems.
