Abstract

Un disyuntor que comprende contactos cooperables, un brazo de contacto que lleva uno de dichos contactos, un miembro de accionamiento funcionalmente conectado a dicho brazo de contacto y operable manualmente para efectuar el movimiento de apertura y de cierre de contactos del mismo, un miembro de estribo movible a una posición bloqueada o enganchada, medios de disparo que responden al flujo de corrientes de sobrecarga a través de los contactos para efectuar la liberación de dicho miembro de estribo con el fin de moverlo desde dicha posición enganchada a una posición de disparo del mismo, y medios de muelle conectados entre el miembro de estribo y el brazo de contacto de tal manera que carguen al miembro de estribo hacia dicha posición de disparo y carguen el brazo de contacto en el sentido de cierre de contactos cuando el miembro de accionamiento está en una posición de "conducción" del mismo y el miembro de estribo está en su posición enganchada, y en el sentido de apertura de contactos cuando el miembro de accionamiento es movido hacia una posición de "no conducción" del mismo o el miembro de estribo se mueve a dicha posición de disparo, incluyendo dicho miembro de accionamiento medios de reposición cooperables con el miembro de estribo liberado para hacer regresar a este último a dicha posición enganchada cuando el miembro de accionamiento es movido a una posición "repuesta" del mismo, caracterizado por unos primeros medios de bloqueo dispuestos de tal manera en el miembro de estribo que golpean el brazo de contacto y apliquen al mismo una fuerza en dicho sentido de apertura de contactos si los contactos cerrados fallan en su intento de abrir tras el movimiento del miembro de estribo a dicha posición de disparo, y unos segundos medios de bloqueo dispuestos de tal manera en el brazo de contacto que bloquean el retorno del miembro de estribo desde la posición enganchada del mismo cuando el miembro de accionamiento es movido hacia dicha posición "repuesta" mientras los contactos están todavía cerrados.
