The invention concerns a device for protection against voltage surges in an electric power supply line. Said device is characterised in that it comprises at least two elements (1', 3), namely a Zener diode lightning arrestor (1') fast-blow in short circuit, and a varistor (3), arranged in parallel, one of the terminals common to said two elements (1', 3) being connected to the line to be protected, and the other common terminal being connected to earth or to a common conductor element.
La présente invention concerne un dispositif de protection contre les surtensions d'une ligne d'alimentation en courant électrique. Ce dispositif est caractérisé en ce qu'il comprend au moins deux éléments (1', 3) à savoir au moins un parafoudre à diode Zener (1') du type à fin de vie en court-circuit, et une varistance (3), qui sont disposés en parallèle, l'une des bornes commune de ces deux éléments (1', 3) étant reliée à la ligne à protéger, et l'autre borne commune étant reliée à la terre ou à un élément conducteur commun.
