Air/gas circuit breakers - Megger

sf 6 circuit breakers suffer less wear on the main contacts than do air and oil circuit breakers. The breaking principle is to cool down the arc by blowing Sulfr hexafluoride gas with high pressure towards the arcing contacts. An Sulfr hexafluoride circuit breaker’s arc extinction method may be characterized as either puffer or self-blast.Get price
