Zusammenfassung:	An arc quenching device for a three-phase electrical switchgear. The device includes a first busbar, a second busbar and a third busbar, each of a respective phase of the three-phase switchgear. The device also includes at least one piston of an electrically conductive material and having a tapered shape, tapering towards its front end. The device also includes only one pyrotechnical actuator arranged to, when the pyrotechnical actuator is fired, axially move each of the at least one piston until all of the first, second and third busbars are short-circuited to each other via the at least one piston.
