Abstract

Mécanisme de commande de disjoncteur permettant l'ouverture normale des contacts sur ouverture de la poignée de commande même lorsque les contacts sont soudés légèrement et un empêchement de la manoeuvre de la poignée de commande lorsque les contacts sont soudés solidement. Il comprend un embiellage articulé à genouillère entre la pièce d'entraînement des contacts mobiles et le levier de déclenchement automatique, l'axe de la genouillère étant engagé dans une lumière d'une bielle articulée. Application : disjoncteur électrique basse tension.
