In the world of electrical distribution and protection, the 400 amp Molded Case Circuit Breaker (MCCB) plays a crucial role. Its ability to safely handle and control electrical currents up to 400 amperes makes it a vital component in various industrial, commercial, and residential applications.

    The 400 amp MCCB is designed to protect electrical circuits from damage caused by overloads, short circuits, and under-voltage conditions. It does this by interrupting the flow of current when these abnormal conditions occur, preventing potential damage to equipment and wiring. The breaker's molded case construction provides a robust and durable enclosure that can withstand the rigors of everyday use in harsh environments.
