Abstract

L'invention est relative à un déclenchement électronique à propre courant associé à un disjoncteur différentiel. Un premier système (22) de commande à circuits de déclenchement temporisé ou instantané pilote en cas de surcharge ou de court-circuit l'amorçage d'un thyristor Th en série avec le relais (20) de déclenchement. Un deuxième système (24) de commande à détecteur DDR de courant différentiel résiduel est agencé pour appliquer directement le signal de déclenchement différentiel aux bornes du relais (20). L'indicateur (40) de déclenchement comporte un circuit logique priorité coopérant avec un circuit d'inhibition destiné à éviter l'affichage erroné d'une alarme différentielle en cas de déclenchement causé par le premier système (22).
