Abstract
The invention concerns a device for protection against transitory overvoltages, comprising: a varistor; a discharge tube; a thermofusible soldering securing a first electrode of the discharge tube and a first electrode of the varistor, the thermofusible soldering being a conductor of electricity and being able to melt beyond a temperature threshold when the varistor or the discharge tube heats up; the second electrode of the varistor being designed to be connected to a first electrical line and the second electrode of the discharge tube being designed to be connected to a second electrical line; a restoring element exerting a restoring force tending to move the first electrode of the varistor away from the first electrode of the discharge tube in order to allow a separation between the first electrode of the varistor and the first electrode of the discharge tube during a melting of the thermofusible soldering.
