  • LF circuit breakers up to 17.5 kV - Schneider Electric

    LF circuit breakers use the SF6 gas self expansion technique. This technique is the result of many years’ experience in SF6 technology and major research work. It combines the effect of thermal expansion with a rotating arc to create arc blowing and quenching conditions. The result is reduced control energy requirements and arcing contact erosion;
