Abstract

Un pont de contacts mobile (13) d'un disjoncteur limiteur à boîtier moulé est porté par un barreau (20) par un système de ressorts (22, 23) autorisant une ouverture à répulsion électrodynamique. Le pont de contact (13) coopère avec des contacts fixes (28, 29) solidaires de conducteurs d'amenée de courant (25, 26) en forme de demi-boucle. Une enclume (33) est accolée à l'arrière des contacts fixes pour accroître l'effet de choc de fermeture du pont de contacts (13) et éviter des dispersions de la résistance de contact. L'enclume (33) est en un matériau ferromagnétique augmentant le champ magnétique de soufflage de l'arc vers les chambres de coupure.
