Outdoor SF6 Vacuum Circuit Breaker(60~80USD/PC)

Description

ZW20 12F series outdoor high-voltage AC demarcation vacuum circuit breakers are high-voltage outdoor switchgear with rated voltage of 12KV and three-phase AC 50H z. They are mainly used to open and close the load current, overload current and short circuit of rural power grids, urban power grids and small power systems. Current. The overall structure of the product is a three-phase common box type, and the three-phase vacuum interrupter is placed in a metal box, with reliable voltage transformation performance and high insulation strength.

Features of outdoor sf6 vacuum circuit breaker

Outdoor sf6 vacuum circuit breaker adopts vacuum interrupter for arc extinguishing, it uses composite insulation structure of epoxy solid and air insulation, which avoids damage to the environment caused by using SF6 gas.
Outdoor sf6 vcb could be remote controlled and automatically protected which also named as Overcurrent fault isolation function: the device has overcurrent protection function, when overcurrent fault occurs at the switch load side, the switch starts instantaneous quick-break function to trip the switch, in order to isolate the overcurrent fault from the main line, thus it does not affect normal operation of the main line;
