Abstract

Relais polarisé possédant un circuit magnétique feuilleté qui comporte une culasse à deux branches reliées entre elles par un aimant permanent, une armature mobile de fermeture, un circuit de commande bobiné sur une des branches de la culasse et un shunt reliant les deux branches, ajusté à l'aide d'un entrefer. Le shunt est constitué par des prolongements des feuilles constituant les deux branches, imbriqués les uns sur les autres et alternativement issus de l'une et l'autre branche, avec interposition entre eux de feuilles minces en matériau amagnétique. L'invention s'applique aux relais de disjoncteurs différentiels.
