Abstract

APPAREIL ELECTRIQUE DESTINE A ETABLIR OU INTERROMPRE LE COURANT DANS UN CIRCUIT ELECTRIQUE. La présente invention concerne un appareil électrique comportant au moins deux paires de contacts fixes (1 à 8), et associée à chaque paire de contacts fixes, un pont P de deux contacts mobiles (9,13) apte à être déplacé entre une première position dans laquelle il relie électriquement ces deux contacts fixes, et une seconde position dans laquelle la circulation du courant entre ces deux contacts fixes est interrompue, ces ponts P de contact mobiles étant montés dans un porte-contacts (14) permettant le déplacement de tous les ponts de contacts mobiles en même temps. Cet appareil est caractérisé en ce que la distance d’ouverture entre d’une part, les contacts fixes de neutre (1,5), et d’autre part, les contacts mobiles de neutre (9,13), est inférieure à la distance d’ouverture entre les contacts fixes de la ou chacune des phases (2,3,4,6,7,8) et les contacts mobiles correspondants de respectivement la ou chacune des phases, de telle manière que lorsque deux contacts respectivement fixe et mobile d’une ligne de phase sont soudés lors de l’ouverture du contacteur, les deux contacts mobiles de neutre (9,13) restent fermés afin que le neutre reste passant, même dans le cas d’une mise en travers du porte-contacts (14) consécutive à la soudure de ces deux contacts respectivement fixe et mobile de phase. Figure pour l’abregé : 2ELECTRICAL DEVICE FOR ESTABLISHING OR INTERRUPTING CURRENT IN AN ELECTRICAL CIRCUIT. The present invention relates to an electrical device comprising at least two pairs of fixed contacts (1 to 8), and associated with each pair of fixed contacts, a bridge P of two movable contacts (9, 13) capable of being moved between a first position in which it electrically connects these two fixed contacts, and a second position in which the flow of current between these two fixed contacts is interrupted, these movable contact bridges P being mounted in a contact holder (14) allowing the movement of all the movable contact bridges at the same time. This device is characterized in that the opening distance between, on the one hand, the fixed neutral contacts (1,5), and on the other hand, the mobile neutral contacts (9,13), is less than the opening distance between the fixed contacts of the or each of the phases (2,3,4,6,7,8) and the corresponding mobile contacts of the or each of the phases, such that when two contacts, respectively fixed and mobile, of a phase line are welded when the contactor opens, the two mobile neutral contacts (9,13) remain closed so that the neutral remains conducting, even in the case of a crossing of the contact holder (14) following the welding of these two contacts, respectively fixed and mobile, of the phase.
