What is MCCB?

MCCB is shorthand for Moulded Case Circuit Breaker. When the total current surpasses the limitation of a micro fuse box, the user employs it as just another sort of overcurrent protection device. The MCCB protects from overvoltages as well as fault current failures, as well as shifting the circuits.

Users may utilize it even in household applications for more outstanding current ratings and fault occurs levels. Users use MCCBs in commercial processes because of their average comprehensive ratings and high breakdown capacity. MCCBs can also safeguard capacitor banks, generators, and the distribution of main electric feeders. When an application requires discriminatory practices, customizable overloading settings, or ground-fault security, it provides suitable protection.Sticking to the belief of “Creating products of high quality and making friends with people from all over the world”, we always put the interest of customers in the first place for Factory wholesale 1600A MCCB Moulded Case Circuit Breaker 3 Pole 400V AC MCCB 3A 380V 63 AMP MCCB 3phase AC CJMM1-400/630 IP CEJIA, “Passion, Honesty, Sound assistance, Keen cooperation and Development” are our targets.
