This short-circuit set, by which it is possible to short-circuit part of the high-voltage distribution equipment, mainly distributors, consists of an insulating board (1) with an arresting pin (5) in which three phase contact pins (2, 20, 200) are firmly mounted on the ends of which are equipped with outside contact bushes (4). Symmetrically to this three earth contact pins (3, 30, 500) are firmly mounted, which are mutually electrically connected to the connecting bar (6) with the hole (7) for the connection of the earth conductor (11) connected to the earth terminal (12) of the sliding carrier (9). The insulating board (1) revolves around the arresting bolt (5) so that the horizontally arranged rows of phase contact pins (2, 20, 200) and earth contact pins (3, 30, 300) can be mutually replaced. The short-circuit set is used with a sliding switch (10) on which it is mounted and by displacing the row of phase contact pins (2, 20, 200) into the selected position it is possible to short-circuit the upper or lower row of switchboard terminals.<IMAGE>
