Abstract

L'invention concerne un appareil électrique de coupure (1) pour une installation, comportant un boîtier (2) et un dispositif de fixation rapide (3) pour l'encliquetage de l'appareil électrique de coupure pour installation (1) sur un rail de support profilé en chapeau (4) comportant au moins un nez de butée (6) mobile situé sur le côté de fixation (5), ce nez de butée venant se plaquer derrière un bord longitudinal (7) du rail de support profilé en chapeau (4) à l'état encliqueté sur ledit rail. Le nez mobile (6) est fixé sur un coulisseau (8) qui porte un cliquet (9) pour l'encliquetage du coulisseau (8) sur le boîtier (2) et le désencliquetage du coulisseau (8) du boîtier (2). Le coulisseau (8), qui présente un profil transversal en forme de U comportant une plaque inférieure (10) et des première et seconde parois latérales (11, 12), est guidé coulissant à l'aide des parois latérales (11, 12) dans des rails de guidage formés dans le côté de fixation (5), et le nez de butée mobile (6) est monté, en tant que nez de butée à ressort, à l'extrémité libre d'un moyen formant ressort (140, 141) relié monobloc au coulisseau (8). Le moyen formant ressort (140, 141) soumet le nez de butée mobile (6) à une force élastique dans la direction du bord longitudinal (7) du rail de support profilé en chapeau (4), de sorte que le moyen formant ressort (140, 141) applique la force de pression du nez de butée mobile (6) sur le rail de support profilé en chapeau (4).
