SF6 Circuit Breakers are high-voltage devices used to protect electrical circuits from overloads and short circuits. They utilize sulfur hexafluoride (SF6) gas as an insulating and arc-extinguishing medium, which enables them to operate efficiently in various environmental conditions. The use of SF6 gas allows for compact designs and enhanced performance compared to traditional air-insulated circuit breakers.
