SURGE VOLTAGE PROTECTION DEVICE WITH IMPROVED DISCONNECTION AND VISUAL INDICATION MEANS

A device for protecting an electrical system against surge voltages, comprising one or more protection components (10), means (20) for disconnecting the protection component (10) and means (30) for visually indicating the state of said component (10), operationally connected to the disconnection means (20) and comprising at least one control part (40) and at least one means (50) for indicating the state of the protection component (10), combined with said control part (40), characterised in that the relative arrangement of said control part (40) and said disconnection means (20) is such that, when the latter are opened (20), they release the control part (40), thereby allowing it to move. Electrical surge voltage protection devices are also described. Se describe un dispositivo para proteger un sistema electrico contra sobretensiones, que comprende uno o mas componentes de proteccion (10), medios (20) para desconectar el componente de proteccion (10) y medios (30) para indicar visualmente el estado del componente (10), conectados operacionalmente a los medios de desconexion (20) y que comprenden por lo menos una parte de control (40) y por lo menos medios (50) para indicar el estado del componente de proteccion (10), combinados con la parte de control (40), caracterizado porque la disposicion relativa de la parte de control (40) y los medios de desconexion (20) es de tal manera que, cuando los ultimos son abiertos (20), liberan la parte de control (40), permitiendo mediante esto que se mueva. Tambien se revelan dispositivos de proteccion de sobre tension electricos.
