Application:
DW15 air circuit breaker is applied to the power-distribution circuit of rated current from 630A up to 6300A, rated operational voltage up to AC 1140V, 50/60Hz. This circuit breaker is mainly used in the distribution network to distribute power, protect circuit and power supply equipment against overload, under voltage and short-circuit faults etc,and Under the normal conditions,it can also be used for circuit of unfrequent transfer. This production conforms the standard of IEC60947-2.
