BreakerDescription: 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. TECHNICAL PARAMETERThe technical parameters of the
