Abstract

Ensemble déclencheur magnétothermique (6) comprenant : un déclencheur thermique, un déclencheur magnétique, et des premier et deuxième leviers d'actionnement (22) ; le déclencheur thermique comportant un bilame (30) adapté pour se déformer pour actionner le premier levier d'actionnement ; le déclencheur magnétique comporte une armature mobile (34), une armature fixe (32) et un conducteur électrique (36) ; l'armature mobile étant adaptée pour se déplacer pour actionner le deuxième levier d'actionnement ; le conducteur électrique et le bilame étant connectés électriquement en série l'un avec l'autre entre des premier et deuxième terminaux de raccordement (10, 12) de l'ensemble déclencheur. L'armature mobile est raccordée au premier terminal de raccordement, l'armature fixe est raccordée au deuxième terminal de raccordement, et les zones de contact respectives de l'armature fixe et de l'armature mobile sont réalisées en des matériaux électriquement conducteurs qui présentent une faible soudabilité entre eux.
