A trip device comprises a removable module for determining long delay tripping parameters, designed to be fixed to a front panel of the trip device. In the fixed position, the removable module exerts a pressure, via an auxiliary part, on a movable part so as to move the latter to a position in which it performs voltage connection of the processing circuit of the trip device to the conductors of a power system to be protected. In an unlocked position of the removable module, the movable part is urged to the disconnected position by a spring. The part can be movable in rotation or in translation.
