Abstract

L'invention concerne un appareil de commutation d'installation (1) pourvu d'au moins un chemin de courant polaire (2) et comportant deux éléments de contact (5,6) fixes et deux éléments de contact (8,9) mobiles disposés sur un pont de contact (7) mobile, ces éléments formant ainsi un interrupteur polaire à deux contacts et double coupure. Le pont de contact (7) est mis en position d'ouverture (O) par un poussoir (12) et en position de fermeture (S) par un ressort de pression de contact (11), les deux contacts étant fermés pour la mise en circuit et, en cas de court-circuit, le pont de contact étant poussé dans le sens de l'ouverture et le poussoir déplacé en position de déclenchement, dans laquelle il agit sur le pont de contact pour l'ouvrir. Selon l'invention, un déclencheur (13) électromagnétique est doté d'un induit qui, en cas de court-circuit, déconnecte le point d'encliquetage d'un verrouillage de connexion (15) de manière à ce que ce dernier, par l'intermédiaire d'un levier d'actionnement (17) en retard de phase par rapport au poussoir (12) et passant d'une position de repos en une position de mise hors circuit, maintienne le poussoir (12) en position de déclenchement, le pont de contact (7) étant alors en permanence contraint en ouverture contre la force exercée par le ressort de pression de contact (11). Cet appareil de commutation d'installation (1) comprend un tiroir de commande (30) logé mobile entre une position de libération et une position de verrouillage, ce tiroir de commande, en position de verrouillage, maintenant le poussoir en position de déclenchement. Le mouvement du levier d'actionnement qui passe de la position de repos à la position de mise hors circuit provoque ainsi le déplacement du tiroir de commande, qui passe alors de la position de verrouillage en position de libération, de sorte que le poussoir (12) est libéré de sa position de déclenchement.
