Abstract

Dispositif de protection électrique Un dispositif de protection électrique (1), comprenant : un coulisseau (10), auquel un le contact mobile (43) d’un chemin de conduction (4) est attaché ; un ressort de contact (13), appliquant un effort de contact (F13) sur le contact mobile, entraînant le coulisseau ; une commande de commutation (5) ; et un déclencheur (8). Pour un déclenchement miniaturisé et rapide, le dispositif (1) comprend un crochet (15), porté par le coulisseau et mobile, entre : une position de verrouillage, pour assujettir la configuration de la commande de commutation à la position du coulisseau, et une position de déverrouillage, pour autoriser le coulisseau à être déplacé de la position armée à la position déclenchée même si la commande de commutation est dans une configuration de fermeture. Le déclencheur déclenche un basculement du crochet vers la position de déverrouillage en étant est excité par un défaut électrique d’un premier type. Figure pour l'abrégé : Figure 2Electric protection device An electric protection device (1), comprising: a slider (10), to which a movable contact (43) of a conduction path (4) is attached; a contact spring (13), applying a contact force (F13) on the movable contact, driving the slider; a switch control (5); and a trigger (8). For miniaturized and rapid triggering, the device (1) comprises a hook (15), carried by the slider and movable, between: a locking position, to secure the configuration of the switching control to the position of the slider, and a unlocked position, to allow the slider to be moved from the armed position to the tripped position even if the switch control is in a closed configuration. The trigger triggers a tilting of the hook towards the unlocking position by being excited by an electrical fault of a first type. Figure for the abstract: Figure 2
