Product Description
DW45
Application
DW45 series air circuit breaker(hereinafter referred to as breaker)is suitable for the circuit of AC 50Hz with rated voltage 400
V, 690V and rated current up to 6300A. It is mainly used to distribute electric energy and protect circuits and power-supply equipment from over-load, under-voltage, short-circuit and single-phase earthing. With intelligentized and selective protection functions, the breaker can improve the reliability of power supply, and avoid unnecessary power failure. The breaker is applicable for power stations, factories, mines(for 690V) and modern high-buildings, especially for the distribution system of intelligentized building. This breaker conforms to IEC60947-2 and GB14048.2
