    The other argument used extensively by advocates of SF 6 technology is that vacuum circuit breakers chop current prior to a natural current zero, and gas breakers do not. This is not completely true, as chopping can occur with any type of interrupting medium, including oil, air-magnetic, vacuum, SF 6 and air-blast circuit breakers.

  • What is Vacuum Circuit Breaker? Construction, Working

    A breaker which used vacuum as an arc extinction medium is called a vacuum circuit breaker. In this circuit breaker, the fixed and moving contact is enclosed in a permanently sealed vacuum interrupter. The arc is extinct as the contacts are separated in high vacuum. It is mainly used for medium voltage ranging from 11 KV to 33 KV.

    Vacuum circuit breakers are more commonly used at system voltage levels up to 72 kV. Because there is no gas to ionize to form the arc, the insulating gap is smaller than in other circuit breakers. An arc does form from the vaporized contact material. The insulation distance in a vacuum circuit breaker is about 11 – 17 mm between plates.
