Abstract

Bloc de protection comportant un étage différentiel (1) muni d'un déclencheur à relais (3) et au moins deux disjoncteurs (2) indépendants protégeant des circuits distincts, chaque disjoncteur (2) comportant ses propres éléments de déclenchement magnétothermiques ainsi qu'une serrure permettant son déverrouillage sur commande de l'étage différentiel (1). Les bornes de raccordement d'entrée (10, 11) du bloc de protection sont reliées à l'étage différentiel. Le bloc de protection comporte des bornes de raccordement de sortie (12, 12'; 13, 13'; 14, 14'; 15, 15'; 16, 16') pour chaque disjoncteur. Les disjoncteurs sont chacun dotés d'un mécanisme de déclenchement (20) relié au déclencheur de l'étage différentiel et/ou au mécanisme de déclenchement d'au moins un disjoncteur adjacent. Lesdits mécanismes de déclenchement sont aptes à exercer simultanément une action de déclenchement sur les serrures des disjoncteurs sur impulsion ou commande du déclencheur de l'étage différentiel.
