Smart Isolation 12KV -ZW32 High Voltage Outdoor Vacuum Circuit Breaker, Tax-inclusive

1. Overview:

ZW20-12F Outdoor AC Intelligent Isolation Vacuum Circuit Breaker (Watchdog) is an outdoor high-voltage switchgear designed for a rated voltage of 12kV, three-phase AC 50Hz. It is mainly used for opening and closing load currents, overload currents, and short-circuit currents in power systems. Suitable for protection and control in substation, industrial and mining enterprises, and urban and rural networks. Particularly suitable for frequently operated sites and urban automated distribution networks. Passed the type test by national institutions and conforms to the following standards: GB1984 High-voltage AC Circuit Breaker.

GB/T11022 Common technical requirements for high-voltage switchgear and control equipment; D11402 Technical specifications for ordering AC high-voltage circuit breakers.
