Abstract

Un interruptor de circuito que comprende contactos separables, medios liberables para efectuar la separación de los contactos cuando se liberan, medios de actuación para efectuar la liberación de los medios liberables cuando son actuados y medios de control para efectuar la actuación de los medios de actuación en respuesta a condiciones predeterminadas de sobrecorriente y de subtensión, comprendiendo dichos medios de actuación un alojamiento tubular de material magnético, un émbolo de material magnético dispuesto en dicho alojamiento, sensiblemente en relación coaxial con el mismo y guiado para moverse axialmente en vaivén entre una posición inicia y una posición actuada, estando dicho émbolo cargado hacia dicha posición actuada y efectuando el movimiento del mismo desde la posición inicial a la posición actuada la liberación de dichos medios liberables, y medios de bobina eléctrica soportados en dicho alojamiento y conectados a los medios de control, comprendiendo dichos medios de controlunos primeros medios destinados a tener aplicada a ellos una tensión de control y que responden a dicha tensión de control para producir una primera señal de salida siempre que la tensión de control esté por encima de un valor predeterminado, y segundos medios que responden a la corriente que fluye a través de los contactos cerrados para producir una segunda señal de salida cuando dicho corriente se eleva por encima de un valor predeterminado, siendo tal la disposición que los medios de bobina permanecen en un estado de excitación que produce una fuerza magnética que mantiene al émbolo en la, posición inicial del mismo contra la acción de su carga mientras es producida dicha primera señal de salida y. está ausente dicha segunda señal de salida, y dicho estado de excitación se modifica para liberar el émbolo a la acción de dicha carga o empuje cuando dicha primera señal de salida decae y/o se produce dicha segunda señal de salida.
