Abstract

Appareil de protection électrique Un appareil de protection électrique (2), comporte : - des contacts électriques séparables (14) aptes à être associés à des conducteurs électriques (4) d’une installation électrique, - un actionneur électromagnétique (10) configuré pour ouvrir les contacts électriques séparables (14) lorsqu’activé, - un déclencheur électronique (18) configuré pour activer l’actionneur électromagnétique lorsqu’un défaut électrique est détecté dans l’installation, et - un circuit d’alimentation électrique (22) alimenté électriquement depuis les conducteurs électriques (4) et configuré pour alimenter électriquement le déclencheur électronique (18), dans lequel l’appareil de protection électrique (2) comporte en outre un dispositif de déclenchement auxiliaire (24, 26) configuré pour détecter une perte d’alimentation électrique en sortie du circuit d’alimentation électrique (22) et pour activer l’actionneur électromagnétique (10) en réponse à une telle perte d’alimentation.
