Abstract

Coupe-circuit (1) en cas de court-circuit à la masse assurant une protection dans l'éventualité d'une perte de neutre (3) ou de terre (4), d'un potentiel excédentaire entre le neutre et la terre et de connexions d'entrée inversées. On utilise des circuits de déclenchement indépendants et séparés lors des défauts précités et des défauts de terre, éliminant ainsi les problèmes dus à des signaux parasites et réduisant la dépendance vis-à-vis de n'importe quel composant ou groupe de composants. On utilise un agencement d'opto-émetteur (25) et d'opto-détecteur (30) afin de détecter et de provoquer le déclenchement d'un coupe-circuit (6) dans l'éventualité de défauts différents des défauts à la terre.
