Working Principle of SF6 Circuit Breaker. In normal operation, the breaker's contacts are closed. When a failure develops in electric system, the contacts get pulled apart, creating an arc between them. The movable contacts are synced to a valve that enters the arc-interrupting chamber with 16kg/cm 2 SF6 gas.
