Summary:The present disclosure relates to an arc quenching device for a three-phase electrical switchgear. The device comprises a first busbar (T), a second busbar (S) and a third busbar (R), each of a respective phase of the three-phase switchgear. The device also comprises a first piston (Pi) and a second piston (P2), each of an electrically conductive material. The device also comprises at least one pyrotechnical actuator arranged with the first and second pistons to axially move each of the first and second pistons if the at least one pyrotechnical actuator is fired. The first and second pistons are arranged in relation to the first, second and third busbars such that said axial movement brings the first piston into contact with both the first busbar and the second busbar, and the second piston into contact with both the first busbar and the third busbar.
