Smart Permanent Magnet Double Mechanism ZW32-12F Watchdog Vacuum Circuit Breaker High Voltage Circuit Breaker

1. Overview:

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

GB/T11022 Common Technical Requirements for High-Voltage Switchgear and Control Equipment; D11402 Technical Conditions for Ordering AC High-Voltage Circuit Breakers.
