Abstract

Perfeccionamientos introducidos en un disyuntor que incluye un par de contactos cooperantes, un brazo de contacto portador de uno (primero) de los contactos y movible en sentidos opuestos con el fin de aplicar dicho primer contacto a, y separarlo de, el otro o segundo de dichos contactos, y una estructura de impulsión magnética que define una ranura que se extiende a través de la misma y en la cual va dispuesta una parte de dicho brazo de contacto de tal modo que una sobreintensidad de corriente que circule por este último y exceda de un valor prefijado induzca en la estructura de impulsión magnética un flujo suficiente para someter el brazo de contacto a una fuerza que impulse a este último en el sentido del desenganche o separación de contactos del mismo, caracterizados por el hecho de que dicho otro o segundo contacto está alineado con un extremo de la ranura en la dirección del movimiento del brazo de contacto, y dicha ranura tiene una parte inferior o de fondo cerrada y un parte superior abierta, espaciadas a cierta distancia de separación en dirección sustancialmente perpendicular a dicha dirección de movimiento del brazo de contacto; y, además, por el hecho de que dicho brazo de contacto se extiende entrando en dicha ranura desde la parte superior abierta de ésta, y tiene una porción que entra en la ranura extendiéndose parcialmente hacia la parte inferior cerrada de ésta.
