AC Motor Protection Circuit Breaker

An AC Motor Protection Circuit Breaker (MPCB) is a crucial component in electrical systems designed to safeguard AC motors from potential damage caused by overloads, short circuits, and other electrical faults. This electromechanical device is equipped with features such as thermal and magnetic protection mechanisms to ensure the efficient and safe operation of AC motors. By automatically disconnecting the circuit in the event of abnormal conditions, the AC MPCB plays a vital role in enhancing the longevity and reliability of AC motors, contributing to the overall safety and performance of electrical systems.
