  • SF6 Circuit Breaker Types, Working Principles

    3 mins readJun 05, 2020SF6 circuit breaker is an extinguisher that uses sulfur hexafluoride gas to cool and quench the arc. It is the type of circuit breaker used to protect electrical grids, power stations, and distribution systems.. Sulfur hexafluoride gas has strong electronegativity and insulating properties, making them a better option than air and oil circuit breakers.
