Abstract

L'invention concerne le matériel de protection des circuits électriques. Un disjoncteur conforme à l'invention, assurant la protection contre des surintensités et diverses autres conditions de défaut comprend notamment des moyens de détection de courant et de tension 11-14, 18-20 ; un convertisseur analogique-numérique 24 qui reçoit les données de courant et de tension par l'intermédiaire d'un multiplexeur 17 ; un microprocesseur 30 programmé de façon à comparer les données de courant et de tension avec des valeurs de réglage prédéterminées et à déclencher le disjoncteur en cas de dépassement ; et une mémoire non volatile 31 destinée à mémoriser les réglages. Application à l'appareillage électrique. (CF DESSIN DANS BOPI)
