Abstract (en)
[origin: EP0398211A1] The invention relates to dielectric gas-blast circuit breakers. <??>The subject of the invention is a dielectric gas circuit-breaker including stationary and moving main contacts, characterised in that it includes a conductive element (25, 30, 35, 150) of high electrical resistance, made to be traversed, following separation of the main contacts, by the current to be cut off. <??>Application to high-and medium-voltage circuit-breakers. <IMAGE>
