China DC Molded Case Circuit Breaker Manufacturers, Suppliers, Factory

DC molded case circuit breaker is the other division of DC circuit breaker. Hereinafter we refer to MCCBs,which works by using a magnetic field to detect fault conditions. When the current reaches or exceeds a predetermined value, the electrical contacts will open and break the connection,stopping the flow of electricity before any damage can occur.Our Polarized 320A molded case circuit breaker can provide a suitable choice for your higher voltage electrical system.

Polarized 320A Molded Case Circuit Breaker is one of molded case circuit breakers.Compared to miniature circuit breaker, our Polarized 320A Molded Case Circuit Breaker can work under 1500VDC which is much greater than 1000VDC and current can reach 320A,which enables it to apply in a 1500VDC electrical system. They have outstanding performance in short-circuit and overload protection.Also they are available in 2P and 3P.
