Circuit Breaker-DZ47le

APPLICATION:

This series of circuit breakers is suitable for AC 50Hz, rated voltage up to 230V/400V, rated current up to 50A, used to protect person against indirect contact, and protect circuitry of buildings or similar line against overload or short-circuit. It also can be over-current protection the equipment against fire caused by lasting earth fault due to the non-operation of over-protection device. In addition, it can be used to switch the circuitry infrequently under normal condition.

The products comply with GB16917&IEC61009.
