Abstract

L'invention concerne une prise de courant prévue dans un système de distribution d'électricité, qui comprend des moyens de commande pour commander l'alimentation électrique vers un dispositif électrique, et à laquelle ce dispositif électrique est connecté. Ladite prise de courant est pourvue d'un interrupteur commandé pour être mis en état d'arrêt par les moyens de commande quand une condition d'état d'arrêt, qui constitue une condition préétablie pour restreindre l'alimentation vers le dispositif électrique, est remplie. L'invention concerne aussi le système de distribution d'électricité comportant cette prise de courant. L'interrupteur peut transiter entre l'état de marche, dans lequel l'alimentation du dispositif électrique est autorisée, et l'état d'arrêt, dans lequel l'alimentation du dispositif électrique est restreinte.
