Product Introduction

Product Overview

 

ZW32-12,24,40.5 outdoor vacuum circuit breaker (hereinafter referred to as circuit breaker) is an outdoor power distribution equipment with rated voltage of 12KV,24KV or 40.5KV and three-phase AC 50Hz. It is mainly used to break and close the load current, overload current and short circuit current in the power system. It is suitable for protection and control in substation and industrial and mining enterprise substation systems, and places where rural power grids operate frequently.

The circuit breaker has the characteristics of small size, light weight, anti-condensation and maintenance-free, and can adapt to harsh weather conditions and dirty environments.
