Abstract

Dispositivo de interrupción que comprende: un par de contactos normalmente cerrados; un par de contactos normalmente abiertos; medios eléctricamente conductores respondientes al calor, estando uno de dichos contactos normalmente cerrados montado con movimiento que le aparta del otro de dichos contactos normalmente cerrados en respuesta al movimiento de dichos medios respondientes al calor, en un sentido, al pasar por los mismos una primera determinada intensidad de corriente; medios portadores de contactos que llevan montado uno de dichos contactos normalmente abiertos, con movimiento cooperativo de cierre con el otro de dichos contactos normalmente abiertos en respuesta a una continuación del movimiento de dichos medios respondientes al calor en dicho sentido al pasar por éstos otra determinada intensidad de corriente, poniendo así fuera de circuito, por derivación, dichos medios respondientes al calor al cerrarse dichos contactos normalmente abiertos; pudiendo ser una parte de dichos medios portadores de contactos movible con relación a una parte de dichos medios respondientes al calor y enganchada cooperativamente por éstos para moverse con los mismos; y medios eléctricamente aislantes de dichas partes.
