ABSTRACT:
An electrical contact construction for air-blast circuit breakers, particularly blast-piston or "puffer" type breakers, which subject the arc drawn during current interruption to a compressed-gas blast as well as a magnetic-force effect which lengthens the arc. To increase the interruption capacity of such breakers, and particularly to improve arc behavior during the interruption process, a tubular member is disposed within the interior spaces of the tubular contacts of such a breaker in which the switching gases flow. The member has an inner surface which is conically shaped and is matched to the contour of openings provided in nozzle members disposed at the end faces of the tubular contacts to improve gas flow.
