Abstract

La présente invention concerne un dispositif de protection (1) pour éviter la propagation d'un court-circuit entre des premier et deuxième réseaux électriques (20,21) dans un véhicule automobile, lesdits premier et deuxième réseaux électriques (20,21) délivrant des tensions continues sensiblement identiques. Il comporte : - des première et deuxième borne d'entrées (12, 13) apte à être connectées respectivement auxdits premier et deuxième réseaux électriques (20,21) ; - une diode (10) montée en série avec un interrupteur commandé (11) normalement fermé entre lesdites première et deuxièmes bornes d'entrée, et - un circuit de commande (14) de l'interrupteur commandé. Selon l'invention, la diode (10) est polarisée de sorte à autoriser le passage d'un courant de la première borne d'entrée (12) vers la deuxième borne d'entrée (13) et l'interrupteur commandé (11) est commandé pour s'ouvrir dès que la tension sur ladite deuxième borne d'entrée (13) passe en dessous d'une tension seuil prédéterminée.
