DZ5 series molded case circuit breakerDetailed product description：

The DZ5 series molded case circuit breaker is suitable for circuits with AC 50Hz, rated voltage up to 400V, and rated current of 0.15-50A. It is used to protect the motor from overload and short circuit. The distribution circuit breaker is used to distribute electrical energy in the distribution network and serve as overload and short circuit protection for lines and power equipment. It can also be used for infrequent starting of motors and infrequent switching of lines.

This product complies with the GB14048.2 standard.
