Abstract

Dispositif de protection électrique Dispositif de protection électrique, comprenant un chemin de conduction, un mécanisme de commutation, une commande de commutation (5) et un déclencheur, qui peut être excité par un défaut électrique d’un type prédéterminé. Le dispositif comprend un système de test, avec un circuit de test et une commande de test (142), qui peut être mise dans une position de test pour que le circuit de test crée un défaut électrique du type prédéterminé. Pour réduire le risque que ces commandes puissent heurter l’utilisateur, le système de test comprend un mécanisme de retenue (16), retenant la commande de commutation (5) dans une position de retenue, lorsque la commande de test (142) est en position de test, et autorisant la commande de commutation (5) à être ramenée jusqu’à une position d’ouverture, lorsque la commande de test (142) est dans une position de repos.
