摘要

A short circuiting device (10) comprises a frame (16) having contact units (14) and placed on a cell or group of cells. The contact units of the frame are in electrical contact with connecting contacts of the cell or group of cells. The frame comprises contact arms (20) supported by a support device (18) and switching devices (22) connected to them. The contact arms are connected to a fluid cooling device. Preferred Features: The switching devices comprise pre-contacts and main contacts which are thermally connected to the fluid cooling device. Several contact units are arranged along the longitudinal extension of the contact arms.
