A self-extinguishing-type of fluid-blast circuit-interrupter is provided, of the single-break type, utilizing a plurality of pressure-generating chambers disposed in series relation, and compartmentalizing the extinguishing chambers so as to act transversely on series portions of the singly-drawn arc. The two pressure-generating chambers are disposed opposite to the fluid-flow transmitting passages, so that there occurs a desirable reduction in temperature of the pressurized fluid prior to its subsequent injection into the arcing region.
