Abstract

L'invention concerne un coupe-circuit électromagnétique. Il comporte une bobine 74 commandant une armature 60 qui porte une masse d'inertie 90 montée de manière à pivoter sur un angle supérieur à celui sur lequel pivote l'armature 60 de manière que le courant circulant dans la bobine 74 et nécessaire pour vaincre la force de rappel exercée sur cette armature 60, pratiquement sans temporisation, soit sensiblement plus grand que le courant nécessaire à un dispositif analogue, mais ne comportant pas la masse d'inertie 90. Domaine d'application : coupe-circuits électromagnétiques, disjoncteurs, etc.
