Vacuum circuit breaker V

Vacuum circuit breaker V

Vacuum circuit breaker cabinet V: breaking short circuit current of vacuum circuit breaker is provided with reclosure function. Between the isolation-ground-vacuum switch of load switch and three-position switch, mechanical interlocking is set and working position indication is displayed on the panel. Relay protection equipment provides overcurrent and quick-break and other protection functions.
