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;
