Abstract
A device for protecting an electrical installation from surges. The device includes a protective component for protecting from overvoltages and two thermal disconnectors. Each thermal disconnector includes a respective mobile contact suitable to move from a closed position to an open position to disconnect the protective component from the electrical installation, and a respective thermosensitive element for making the mobile contact move from the closed position to the open position when the temperature of the protective component exceeds a predetermined threshold.
