A tripping assembly is provided for a switching device. The tripping assembly includes: a body part, a tripping axle configured to turn between a trip position and a tensioned position in relation to the body part; a tripping frame configured to turn between a trip position and a tensioned position in relation to the body part and whose turning axis is substantially parallel with the turning axis of the tripping axle; at least one tripping spring which has an non-tensioned state and a tensioned state and which is functionally connected to the tripping axle and to the tripping frame; a frame spring which has a non-tensioned state and a tensioned state and which is functionally connected between the body part and the tripping frame; and a connecting member which is arranged to functionally connect the tripping axle and the tripping frame both in the final stage of a tensioning event and in the initial stage of a tripping event. In the tripping event: (i) both the frame spring and the at least one tripping spring are configured to transfer from the tensioned state to the non-tensioned state, thus releasing energy needed for the tripping event to the tripping assembly; and (ii) the tripping frame and the tripping axle are configured to turn from their tensioned positions to their trip positions, and while doing so, to turn to opposite directions with respect to one another.
