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.
