Description:
Air circuit breaker is suitable for the circuit of AC 50Hz with rated service voltage 400V,690V and rated service current up to 6300A. It is mainly used to distribute electric energy and protect circuits and electric equipment against over-load, under-voltage, short-circuit and single-phase earthing fault. 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 and modern high-buildings, especially for the distribution system of intelligent buildings.
