Abstract

Grâce à la connexion d'un fusible (1a) comportant un élément fusible constitué d'une matière qui fond entre 600 °C et 850 °C avec une extrémité d'un conducteur M (2), la température d'accumulation du conducteur M (2) ou de la partie de connexion entre une borne M (8) et le conducteur M (2) est détectée, si bien que l'élément fusible fond pour couper le circuit d'un moteur (21) et pour arrêter l'accumulation de chaleur avant que la chaleur d'accumulation n'atteigne 900 °C, température à laquelle un revêtement isolant (3) et un boîtier de contact sont rompus thermiquement. On peut ainsi éviter, par un procédé peu onéreux, la défaillance par rupture thermique d'un démarreur de structure simple et de petite taille, sans détériorer la disposition de montage et la performance nominale.
