parameters

ZN63 (VS1) -12 type vacuum circuit breaker is indoor high voltage switchgear, suitable for three-phase power system with rated voltage of 12KV and frequency of 50HZ. It’s used to protect and control electrical appliances, especially suitable for special advantages of vacuum circuit breakers In the frequent operation of the need for rated current, or short-circuit breaking current place.

ZN63 (VS1) -12 type solid sealed (VBM7) vacuum circuit breakers using fixed installation, mainly for fixed switchgear, the circuit breaker can be used alone, but also for the ring network power supply, box substation or Non-standard power supply system.
