Audited Supplier W1 series air circuit breaker(hereinafter called ACB) is suitable for the circuit of AC 50Hz/60Hz with rated service voltage 400V, 690V and rated service current between 200A and 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 intelligent 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.
The circuit breaker complies with standards such as GB 14048.2 Low-voltage switchgear and controlgear Part 2: Circuit- breakers and IEC60947-2 Low-voltage switchgear and controlgear-Part 2: Circuit-breakers.
