Abstract

L'invention concerne un dispositif de protection contre les surtensions pour des terminaux électriques qui, en plus d'une connexion au réseau à basse tension au moins monophasée, disposent d'au moins une borne de signal de commande. Une modification de l'état opérationnel du terminal correspondant peut être prédéfinie par le biais de la borne de signal de commande. Le dispositif de protection contre les surtensions se compose d'un ensemble de varistances auxquelles sont respectivement associés un dispositif de coupure thermique et un indicateur de fonctionnement visuel, et comprend au moins un éclateur à gaz branché entre la connexion au réseau et un conducteur de terre. Une première varistance munie d'un dispositif de coupure thermique se trouve en outre entre la connexion au réseau et un conducteur neutre et une seconde varistance munie d'un dispositif de coupure thermique entre la borne de signal de commande et le conducteur neutre. Le dispositif de protection contre les surtensions est en outre disposé à proximité immédiate du terminal électrique, notamment dans un coffret de raccordement.
