Item Name: ZW8-12 series Outdoor Vacuum Circuit Breaker

Item Name: ZW8-12 series Outdoor Vacuum Circuit Breaker

The ZW8-12 series outdoor HV vacuum automatic circuit reclosers(short for brea) be used for switching on/off load current, overload current and short circuit current in three-phase power systms with AC 50Hz and rated voltage 12KV. Matching with recloser controllers, the breaker can identify current characteristic and realize repetitious autoeclosing or permanent fault isolation. With its own PT power, it becomes an intelligence breaker having controlled voltage and current signal output. With electric PT Power, It povides three segment compound protection of over current time delay, rush current time delay and short circuit quick break.
