What is the breaking principle for SF circuit breakers?

SF circuit breakers use the puffer principle with SF6 gas. This methods cools and extinguishes the electrical arc as it passes through zero current by puffing a gas compressed by a piston attached to the moving contact. The gas is channeled by an insulating nozzle towards the tubular arcing contacts that are used as an exhaust.
