Abstract
A puffer-type compressed-gas circuit-interrupter is provided having a tubular stationary and at least two movable contacts which draw at least two arcs within at least two regions in the interrupter. The two regions are connected by a series of insulating flow guides, tubular contacts, and an insulating nozzle to a single fluid motor which during contact opening, after a predetermined portion of the opening travel of the interrupter, provides a blast of puffer gas extinguishing the arcs.
