ADVANTAGES OF VACUUM CIRCUIT BREAKER
Vacuum circuit breaker does not require any additional filling of
oil or gas. They do not need periodic refilling.
Rapid recovery of high dielectric strength on current interruptions
that only a half cycle or less arcing occurs after proper contact
separation.
Breaker unit is compact and self-contained. It can be installed in
any required orientation.
Because of the above reasons together with the economic advantage
offered, vacuum circuit breaker has high acceptance.
