Abstract

L'invention concerne un branchement d'utilisateur (5; 7) pour une unité de distribution de courant (1), en particulier un branchement de moteur pour un équipement de commutation basse tension, comportant un système de contact d'alimentation (34; 134) pour la mise en contact d'un circuit électrique principal, un système de contact de sortie (34; 234) pour la mise en contact du circuit électrique principal et un moyen d'identification (40; 140) pour l'identification dans l'unité de distribution de courant (1) d'une position de déconnexion du branchement d'utilisateur (5; 7) dans laquelle le système de contact d'alimentation (34; 134) et le système de contact de sortie (34; 234) sont déconnectés du circuit électrique principal. L'invention vise à créer une identification encore plus fiable de la position de déconnexion des différents branchements d'utilisateur dans l'unité de distribution de courant. A cet effet, le moyen d'identification (40; 140) comporte une première section (41; 141) réalisée sous la forme d'une barrière mécanique, qui empêche une mise en contact du système de contact d'alimentation (34; 134) et/ou du système de contact de sortie (34; 234) avec le circuit électrique principal.
