PCT No. PCT/DE95/00631 Sec. 371 Date Nov. 26, 1996 Sec. 102(e) Date Nov. 26, 1996 PCT Filed May 8, 1995 PCT Pub. No. WO95/33274 PCT Pub. Date Dec. 7, 1995A compressed-gas circuit breaker is provided with two contacts arranged coaxially opposite one another, at least one of which can be driven to move in the axial direction. The two contacts define in the interrupted state a contact gap. The circuit breaker also has a nozzle, made of insulating material, which is connected to the driven contact and which surrounds at least part of the contact gap. The invention calls for a high-strength plastic tube abutting coaxially against the outside of the insulating nozzle in order to prevent the nozzle from expanding radially as a result of an increase in arc-extinguishing gas pressure.
