Vacuum Circuit Breaker
ZW10-12/630-20 series outdoor AC high-voltage vacuum circuit breaker is a three-phase AC 50Hz, outdoor high-voltage switchgear. It is mainly used in 12KV rural and urban power systems to open and close load current, overload current and short-circuit current. It can also be used in other similar places.
The circuit breaker can be equipped with an isolating switch to form a combination electrical appliance;
Can be equipped with a reclosing controller to form a recloser;
Manufacturer data — model designation, technical parameters, dimensions and installation details.
Special anti-condensation measures are adopted inside to ensure insulation inside the box;
The transmission method adopts patented technology, which is easy to install and reliable in operation, avoiding the impact of mechanical failure on the performance of the circuit breaker;
No oil filling, no air filling, small size, light weight, CT protection;
The operation can be electric or manual.
Note: When the product is used at a location exceeding 1000m, the insulation level should be corrected.
