IEC Standards 2000A 3P Fixed Type Air Circuit Breaker

1.modern high-buildings

(especially for the distribution system of intelligentized building).

2.mines(for 690V).

3.power stations.

4.factories.

*It is mainly used to distribute electric energy.protect circuits and power-supply equipment from overload,under-voltage,short-circuit and single-phase earthing. with intelligentized and selective protection functions, the breaker canimprove the reliability of power supply, and avoid unnecessary power failure.
