Outdoor VCB/ACR Product Description

11kV 12kV 630A Vacuum Auto Recloser Circuit Breaker 

Applicable place: (Suitable for the places frequently operated with rural power grid)

1. Industrial.

2. Power stations.

3. Substations.

It can avoid aerial without the time, protect power, power fault accident narrow scope, shorten the time, protect power users of the main safety operation.

Recloser Advantages

1. Equipped with vacuum arcing chamber of the column in vacuum circuit breaker.
2. Circuit breaker using fully closed structure, sealed performance is good, help to improve the moistureproof, prevent condensation performance;

3. It can detect the limit value and judge the milliampere zero sequence current, and alternate with the short-circuit fault current to automatically cut off a single ground fault;

4. It has fault detection function, protection control function and communication function;
5. The operation is sealed inside the switch, which can effectively avoid the rusting of the mechanism caused by the outdoor environment of the switch for a long time.
6. The operation is novel, simple, reliable, small, and the mechanical life can reach 10000 times.
