Fixed Type Automatic Circuit Breaker DW45 ACB Air Circuit Breaker

Do Better Performances in Demanding Duties

Application of Intelligent Air Circuit Breaker(ACB) 

Frequency:50Hz

Rated voltage:400V,690V

Rated current:4000A

Applicable place:

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 can improve the reliability of power supply, and avoid unnecessary power failure.               circuit breaker manufacturers/ dw45 air circuit breaker/ fixed-mounted circuit breaker
