Product Details

1. Best quality ZN12-40.5KV Series fixed type vacuum circuit breaker VCB

ZN12-40.5 series indoor high voltage vacuum circuit breaker is mainly 35KV three-phase AC 50HZ applied to power system, the circuit breaker for the ceramic structure, using the longitudinal magnetic field contacts, is small, the proliferation of breaking arc generated when current distribution in the contact on the same local melting phenomenon does not occur, but also has a low arc energy voltage (20-200V) and low chopping current (4-5A), and operate with high reliability organizations.

2. Highlight of VCB

The switch of simple structure, open high capacity, long life operation of fully functional no explosion risk, maintenance is simple, suitable for power plants, substation control and distribution system, protection switching, particularly suitable for heavy duty and frequent breaking operation place.
