Abstract

Un elemento fusible para la extinción de arcos magnéticos, que tiene medios electroconductores bifurcados (10, 16, 28) con terminales primero y segundo (6, 8) en extremos opuestos para la conexión de los medios electroconductores bifurcados a un circuito eléctrico y los medios electroconductores bifurcados, que tienen entre los componentes primero y segundo al menos un punto débil (12, 24, 42) primero y al menos un punto débil segundo (18, 32, 40) de material fusible y al menos porciones de los puntos débiles primero y segundo yendo dispuestas substancialmente paralelas entre sí caracterizado por el hecho de que el primer y segundo punto débil van dispuestas de tal manera que el flujo de la corriente, entre el primer y segundo terminal, en la porción paralela (12, 82, 92) del primer punto débil es opuesto en sentido direccional al flujo de la corriente en la porción paralela (18, 80, 90) del segundo punto débil; por lo que se genera entre el primer y segundo punto débil una fuerza magnéticade repulsión alargando de este modo los arcos formados en los puntos débiles por una sobreintensidad, que pasa a través de ellos.
