Vacuum Circuit Breaker Manufacturers and Suppliers What is a vacuum circuit breaker? A vacuum circuit breaker is a type of electrical switching equipment used in power systems to protect circuits and equipment from damage by quickly cutting off current when a circuit fault occurs. Often referred to as a vacuum arc extinguishing circuit breaker, its operating principle is based on the arc extinguishing that occurs in a vacuum environment. Principle of operation of vacuum circuit breakers The primary mechanism of a vacuum circuit breaker is the removal of arc energy between the contacts.
