  • Comparison Between Vacuum and SF6 Circuit Breaker

    10 mins readAug 29, 2018For the vacuum-circuit breaker the service interval lies between 10,000 and 20,000 operations. For the SF6 designs the value varies between 5,000 and 20,000 whereby, the lower value applies to the puffer circuit-breaker for whose operation, the mechanism must deliver much more energy.switchgear
