Abstract

Abstract Translated from French Interruptuer dans lequel un écran passant entre les contacts effectue un cisaillement de l'arc d'ouverture. L'écran (27) est associé à un étui (22) entourante un support de contacts (7, 1, 2) et glisse sur celui-ci lorsque la pression des gaz qu'il reçoit le déplace avec une vitesse qui est fonction de l'énergie de l'arc. Cet interrupteur est en particulier applicable aux appareils de protection devant limiter des courants accidentels ou à des appareils de coupure traversés par des courants établis relativement importants. Switch in which a screen passing between the contacts shears the opening arc. The screen (27) is associated with a case (22) surrounding a contact support (7, 1, 2) and slides thereon when the pressure of the gases which it receives displaces it with a speed which is a function of the energy of the arc. This switch is in particular applicable to protective devices having to limit accidental currents or to breaking devices crossed by relatively large established currents.
