ABB (Air Blast Breaker), perhaps, as used on electric trains @ 25kV?
I'm not sure of the precise way it works but consists of a blast of high pressure air between the contacts to extinguish the arc.
I wonder if it actually blows the arc sideways so that it forms a sort of 'U' shape, thus extending the length of the arc very rapidly so that it extinguishes in a much shorter time?
