The vacuum circuit breaker is indoor switchgear components insulated by air. Under normal conditions of use, it can operate safely and reliably within the corresponding voltage level of the grid, as long as in the range of the technical parameters of the circuit breaker. VS1 vacuum circuit breaker is suitable for reclosing operation, and it can operate frequently or break repeatedly in the current range of the work. What's more, its mechanical life is up to 10,000 times, and its full capacity short-circuit current breaking times is up to 50 times.

The installation forms of VS1 vacuum circuit breaker in the switchboard can be either fixed or drawable, and it can also be installed on the frame.
