  • Nameplate details of SF6 Circuit Breaker | Explained

    In SF6 circuit breaker, arc extinguishes during current zero. As in 3 phase AC circuit, currents are out of phase by 120&, current interruption in breaker is not simultaneous. Contact of one pole will open before the other two. And hence, the power frequency recovery voltage across the first pole to open is more than the other two.
