Abstract

Disjoncteur comprenant un déclencheur de surintensité à bilame ainsi qu'un déclencheur de court-circuit comprenant un noyau magnétique entouré par une bobine ainsi qu'une armature qui agit sur un levier d'ouverture de contacta Le noyau magnétique 15 est monté de manière à pouvoir coulisser à l'intérieur de la bobine et il est relié à la bilame 13 à déclenchement thermique de manière qu'elle le translate vers l'armature 16 lorsqu'elle s'échauffe et fléchit, en diminuant la largeur de l'entrefer compris entre ce noyau 15 et cette armature magnétique 16. Application générale aux disjoncteurs automatiques afin d'en accroître la sensibilité de réponse aux surintensités.Circuit breaker comprising a bimetal overcurrent release as well as a short-circuit release comprising a magnetic core surrounded by a coil as well as an armature which acts on a contact opening levera The magnetic core 15 is mounted so as to be able to slide inside the coil and it is connected to the bimetallic strip 13 with thermal release so that it translates it towards the reinforcement 16 when it heats up and bends, by reducing the width of the air gap between this core 15 and this magnetic armature 16. General application to automatic circuit breakers in order to increase their response sensitivity to overcurrents.
