The 100 amp MCCB, or Molded Case Circuit Breaker, is a crucial component in electrical systems, providing vital protection against overloads and short circuits. Its role is pivotal in ensuring the safe and efficient operation of various electrical circuits, particularly those carrying high currents. In this article, we delve into the fundamentals of the 100 amp MCCB, exploring its working principle, applications, and significance in modern electrical systems.

    The 100 amp MCCB is designed to interrupt the flow of current in an electrical circuit when an abnormal condition occurs. It operates by utilizing a combination of thermal and magnetic trip mechanisms. The thermal trip mechanism detects overloads by monitoring the temperature rise in the circuit. When the temperature exceeds a certain threshold, indicating an overload condition, the thermal trip activates, tripping the breaker and disconnecting the circuit.
