The invention relates to electrical cutoff equipment (1), particularly a breaker, including two electrical arc contacts (5a, 5b) designed to be moved from a closed position to an open position, during an opening operation, by means of relative translational movement along a central axis (19) of said arc contacts. According to the invention, the equipment additionally comprises means (54, 56) for rotation that enable the arc contacts (5a, 5b) to be rotated relative to one another along the central axis (19), at least after separating the arc contacts during an opening operation. |
