In today's advancing electrical landscape, the 400VAC Molded Case Circuit Breaker (MCCB) stands as a cornerstone of safety and reliability. With its ability to swiftly and efficiently isolate faulty circuits, the 400VAC MCCB has become an indispensable component in numerous industrial, commercial, and residential applications.

    The 400VAC MCCB is a multi-functional protective device that is designed to monitor and safeguard electrical circuits operating at a nominal voltage of 400 volts alternating current (VAC). Its primary function is to detect and interrupt abnormal current conditions such as overloads, short circuits, and ground faults. By doing so, the MCCB prevents damage to electrical equipment, minimizes the risk of fires, and ensures the continuity of power supply to unaffected circuits.
