CDB6iZ DC miniature circuit breaker

CDB6iZ DC series  circuit breaker is mainly suitable for circuits with rated working voltage DC250V and rated current 16-63A. 

CDB6iZ DC series  circuit breaker is mainly suitable for circuits with rated working voltage DC250V and rated current 16-63A. It can realize full selective protection with the lower-level circuit breaker to ensure that the system can effectively avoid the malfunction of the upper-level circuit breaker caused by the lower-level short-circuit current while realizing the short-circuit fault protection function, and ensure the safety and security of the system to the greatest extent. Reliable operation, widely applicable to DC power systems such as power sources and substations.
