Detailed Product Description
Vacuum circuit breaker
1. Application:
ZW32-12 series pillar type outdoor vacuum circuit breaker is a kind of outdoor high voltage switch equipment with 50Hz three-phase alternating current and 12Kv rated voltage. It apply to break and close the load current, overload current and short-circuit in sities or country power distribution system.
