Abstract
A transient overvoltage protection system to be positioned in parallel with an equipment item to be protected, has at least three lines and includes three conductive branches intended to be connected to the three lines. The first and second conductive branches are equipped with first and second voltage-sensitive protection elements and are able to rise in temperature when the voltage between its terminals is higher than a voltage threshold. A thermally sensitive disconnection device comprising at least one thermofusible element in thermal contact with at least one of the first and second protection elements, is arranged so as to keep the three branches in a connected position, the thermally sensitive disconnection device having an elastic return device exerting a force tending to bring the three conductive branches to a disconnected position.
