(Electromagnetic) (electric) model specifications DW15-200A DW15-400A DW15-200A DW15-630A DW15-1000A DW15-160A DW15-2500A DW15-4000A DW15 Series Circuit Breaker (hereinafter referred to as breaker) for AC 50HZ , rated current up to 1600A, rated working voltage up to 1140V (frame degree rated current 630A) or 380V (frame degree rated current 1600A) of the distribution network for the distribution of power and used as power lines and equipment overload, underload voltage, short circuit protection. Description: A range of applications frame degree rated short-circuit current 630A can also exchange 50HZ, 380V network as a motor overload, under-voltage and short circuit protection. Under normal conditions, the circuit breaker can be used as infrequent conversion of the lines used, frame degree rated current of 630A breaker under normal conditions can also be used as the conversion of motor infrequent use.
