After contact separation, current is carried through an arc and is interrupted when this arc is cooled by a gas blast of sufficient intensity. SF6 gas is electronegativeand has a strong tendency to absorb free electrons. The contacts of the breaker are opened in a high pressure flow of sulfur hexafluoride gas, and an arc is struck bet…See more on en.wikipedia.orgEstimated Reading Time: 12 minsWhat is SF6 Gas? | GasQuip SF6 Equipment and Training gasquip/what is sf6 gas2020/9/16Sulfur hexafluoride can be used on switch gear that is up to 6,300A (6.3kA), or about 420 times that of your home plug.
