In the intricate landscape of electrical systems, the Molded Case Circuit Breaker (MCCB) stands as a pivotal component, particularly the 400VAC variant, which plays a crucial role in ensuring the safety and reliability of electrical circuits. This article aims to delve deeper into the significance and functionality of 400VAC MCCB, highlighting its importance in modern electrical protection systems.

    The 400VAC MCCB is designed to operate effectively in circuits with a rated voltage of 400 volts alternating current (AC). This specific voltage rating makes it suitable for a wide range of applications, including industrial, commercial, and residential settings. The MCCB's primary function is to provide a means of manually switching the circuit on or off, as well as to automatically trip and disconnect the circuit in the event of an overload or short circuit.
