Product Introduction

ZW32-12 outdoor high-voltage pole vacuum circuit breaker is suitable for three-phase AC 50Hz, rated voltage 12KV and below power distribution system, mainly used for switching load current, overload current and short-circuit current of switching lines, and can also be used as agricultural The section switch of the power grid and small power system is an upgraded product of the oil-free transformation of urban power grids and rural power grids.

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

Features

High reliability, high mechanical and electrical life;
No maintenance;
Small size, lightweight, easy to install;
Standard relay protection and quick automatic reclosing function;
