Abstract (en)

Circuit breaker comprises housing, opening mechanism with energy accumulator, and poles. Each pole has auxiliary mechanism w energy accumulators drawing back support (58) towards opening position on all or part of support stroke, between closing positio and intermediate tipping over position, but more further than intermediate position.

Abstract (fr)

Un disjoncteur basse tension limiteur comporte un organe de contact fixe et un organe de contact mobile 50 comportant lui-même un support 58 pivotant autour d'un axe fixe 60 entre une position de fermeture et une position d'ouverture, un doigt de contact 62 pivotant autour d'un axe fixe 64 entre une position non répulsée et une position répulsée, et un dispositif bistable 80 comportant un ressort 82 disposé entre le support 58 et le doigt 62. Lorsque le doigt 62 est positionné dans sa position répulsée et que le support 58 pivote de sa position de fermeture vers sa position d'ouverture, il entraîne le doigt 62 dans sa position non répulsée. Une partie de l'énergie nécessaire pour passer le point mort du dispositif bistable 80 est fournie par un ressort 92 qui rappelle le support 58 vers sa position d'ouverture uniquement au début de l'ouverture, ce qui permet de ne pas surdimensionner le ressort d'ouverture du disjoncteur. <IMAGE>
