ZW32-12/630-20 Double-Pole Permanent Magnet High-Voltage Circuit Breaker, Outdoor High-Voltage Vacuum Circuit Breaker, Pole-Mounted Switch

1. Overview:

ZW20-12F outdoor AC intelligent boundary vacuum circuit breaker (watchdog) is a high-voltage outdoor switchgear rated for 12kV, 3-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 grids for protection and control, especially suitable for frequently operated sites and urban automated distribution networks. Passed the type test by the national *** agency 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.

2. Terms of Use:
