In the realm of electrical distribution and protection, the 400 amp molded case circuit breaker (MCCB) stands as a crucial component. Its robust design and ability to handle significant electrical loads make it a valuable asset in various industrial and commercial applications.

    The 400 amp MCCB is a type of low-voltage electrical switchgear that is designed to protect electrical circuits from damage caused by overloads and short circuits. Its name is derived from the fact that it can safely carry and interrupt up to 400 amperes of current. This rating ensures that the breaker can handle a wide range of electrical loads, from small office buildings to large industrial facilities.
