ZW32 Outdoor Vacuum Circuit Breaker, Integrated Primary and Secondary, Independent Neutral Sequence Intelligent Vacuum Circuit Breaker

Supply ZW32-12/630-20 intelligent vacuum circuit breaker, integrated one-and-two pole column-mounted high voltage circuit breaker

1. Main Application

The ZW32-12 type outdoor pole-mounted high-voltage vacuum circuit breaker (hereinafter referred to as the circuit breaker) is an outdoor distribution equipment rated at 12KV, 3-phase AC 50HZ. It is mainly used for opening and closing the load current, overload current, and short-circuit current in the power system. Suitable for protection and control in substation and mining enterprise distribution systems, it is also particularly suitable for rural power grids and frequently operated sites, especially for urban and rural grid transformation needs.

This installation and usage manual specifies the main technical parameters, product structure, as well as the principles and methods of operation, installation, and maintenance of the circuit breaker.
