Abstract

Disjoncteur électrique perfectionné. Disjoncteur qui utilise comme mécanisme de déclenchement une bobine électromagnétique ou un solénoïde dont les spires sont constituées par un ressort hélicoïdal présentant un effet mnémomorphe et qui agit mécaniquement sur l'armature. Un ressort normal, agit également sur l'armature, mais dans une direction opposée à celle du ressort mnémomorphe. Le courant passe dans le ressort mnémomorphe et quand son intensité devient excessive, l'armature est sollicitée à la fois mécaniquement et électromagnétiquement dans la direction du déclenchement. S'applique à la protection des installations et des circuits électriques contre les surintensités.
