  • Circuit breakers SF 1 to 40.5 kV SF6 - Schneider Electric

    SF6 circuit breakers use the SF6 auto-compression technique. The main contacts and the arcing contacts are initially closed (fig. 1). Pre-compression (fig. 2) When the contacts begin to open, the piston slightly compresses the SF6 gas in the pressure chamber. The arcing period (fig. 3) The arc then forms between the arcing contacts.
