Abstract

Un dispositivo contador eléctrico capaz de limitar sobreintensidades, teniendo dicho contactor, por lo menos, una unidad de polo que incluye una estructura de contacto estacionario con un contacto estacionario y una estructura de contacto móvil con un contacto móvil y unos medios de accionamiento para efectuar los movimientos de apertura de contactos y cierre de contactos de la estructura de contacto móvil, caracterizado dicho contactor por el hecho de que dicha estructura de contacto móvil comprende un conductor alargado y elástico que lleva formado un bucle de inversión e incluye una porción en voladizo que se extiende a partir de uno de los extremos del conductor hasta dicho bucle de inversión, en el cual forma el voladizo, y dicha porción en voladizo es portadora del citado contacto móvil, incluyendo dicho conductor dos segmentos dispuestos en lados contrarios respecto de dicho bucle de inversión, de modo que la corriente que pase por el conductor circule recorriendo dichos segmentos ensentidos opuestos.
