    SF6 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 SF6 gas with high pressure towards the arcing contacts. An SF6 circuit breaker’s arc extinction method may be characterized as either puffer or self-blast.
