Abstract
Déclencheur différentiel polarisé à deux bobinages normalement équilibrés sur un circuit magnétique fermé. Le circuit magnétique fermé comporte une culasse à deux branches, un aimant permanent et une armature mobile de fermeture; les deux bobinages sont enroulés sur le circuit magnétique de telle façon que le flux différentiel qu'ils engendrent soit inverse de celui de l'aimant. L'invention s'applique notamment à la commande d'un disjoncteur.
