Abstract

La présente invention concerne un conducteur de connexion de puissance qui permet de monter de manière compacte des disjoncteurs et des commutateurs électromagnétiques sur un tableau de distribution électrique sans qu'il en résulte une augmentation de la surface du tableau de distribution électrique ni une exécution de travaux complexes de câblage. Ledit conducteur de connexion de puissance réduit également les erreurs de câblage et le nombre d'heures-personne nécessaires au câblage. Afin de connecter un disjoncteur aux bornes de connexion sur un dispositif électrique tel qu'un commutateur électromagnétique (2a, 2b), le conducteur de connexion de puissance a des barres de conduction formées intégralement de fils électriques, pour une pluralité de phases de puissance, enfermés à l'intérieur d'un élément isolant. Le conducteur de connexion de puissance a une section de base en forme de plaque qui est disposée, au moins, entre le côté d'ancrage d'un disjoncteur et le côté frontal d'un commutateur électromagnétique. Les barres de conduction sur les deux extrémités de la section de base en forme de plaque sont connectées, respectivement, aux bornes de connexion secondaires sur le disjoncteur et aux bornes de connexion primaires sur le commutateur électromagnétique.
