  • Air/gas circuit breakers - Megger

    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.

  • Sulfur hexafluoride circuit breaker - Wikipedia

    Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride (SF 6) gas to cool and quench the arc on opening a circuit. Advantages over other media include lower operating noise and no emission of hot gases, and relatively low maintenance.

  • Circuit breaker - Wikipedia

    Gas (usually sulfur hexafluoride) circuit breakers sometimes stretch the arc using a magnetic field, and then rely upon the dielectric strength of the sulfur hexafluoride (SF 6) to quench the stretched arc. Vacuum circuit breakers have minimal arcing (as there is nothing to ionize other than the contact material).
