ZW32-12/630-20 outdoor vacuum circuit breaker is a three-phase AC 50Hz outdoor high-voltage switchgear with a rated voltage of 12kV. It is mainly used to switch load current and break overload current and short circuit current in power system.
The overall structure is a three-phase pillar dry structure;
Using a fully enclosed structure, good sealing performance, good moisture-proof and anti-condensation performance, and can be used in high temperature and humid areas;
Reliable breaking and closing performance, no burning and explosion hazard;
Small size, light weight, maintenance-free, and long service life;
The opening and closing operations can be manual or remote control;
The operating mechanism is sealed at the bottom of the switch box, which can effectively prevent the switch from corrosion due to long-term outdoor exposure.
