塑造了案件的断路器

APPLICATION JDM1(CM1)series moulded case circuit breaker (hereinafter referred to as circuit breaker) is suitable for distribution network of AC50Hz, rated working voltage 690V (JDM1-63 is 500V) and below, rated current 1250A and below, used to distribute the electric energy and protect the circuitry and power unit against overload, under-voltage or short-circuit. Circuit breakers whose frame size is 400A below also can be used to protect the motor against overload, under-voltage of short-circuit. In addition, it can be used to switch the circuitry and start the motor infrequently. The products comply with IEC6094-2, they can be vertically installed or horizontally installed.
