Air Circuit Breaker

1.1 Application scope

NA1 series air circuit breaker is suitable for the circuit of AC
50Hz/60Hz 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, mines (for 690V) and modern high-
buildings, especially for the distribution system of
intelligentized building.
