Abstract

Ce dispositif de protection (4) d’une charge (2) comprend un pyrofusible (6) couplé à un relais électromagnétique (7) comprenant des moyens actionneurs (71) aptes à faire passer ledit relais (7) d’un premier état de fonctionnement (P1) dans lequel la charge est alimentée à un deuxième état de fonctionnement (P2) autorisant la délivrance d’un courant de commande à l’une des bornes d’entrée du pyrofusible, lorsque le courant d’alimentation de la charge est supérieur à une valeur seuil, provoquant une rupture irréversible du pyrofusible alimenté, pour découpler la charge d’une source d’alimentation délivrant le courant d’alimentation.
