A vacuum circuit breaker is a kind of breaker that utilizes a vacuum as an arc extinction medium. The fixed and moving contact is enclosed within a vacuum interrupter that is permanently sealed. When the contacts separate in a high vacuum, the arc is extinguished. The vacuum circuit breaker is primarily used for medium voltage ranging from 6.6 kV to 33 kV.
