What is SF6 Circuit Breaker? Construction, Working ... Hexafluoride (SF6) Circuit Breaker A circuit breaker in which SF 6 under pressure gas is used to extinguish the arc is called SF 6 circuit breaker. SF 6 (sulphur hexafluoride) gas has excellent dielectric, arc quenching, chemical and other physical properties which have proved its superiority over other arc quenching mediums such as oil or air. . The SF 6 circuit breaker is mainly ...
