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 equipmetnagainst 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 interlligentized building.
