Abstract (en)

[origin: EP0893806A2] The arrangement (1) includes a primary conductor passing through a current converter (7), which is formed as element of a branch current path (6) of a main current conductor (2). The main current conductor has a rectangular cross-section with opposite narrow sides (4) and broadsides (5), and is formed through a connection rail of a low-voltage power switch. The branch current path comprises a centrepiece (10) extending crosswise to the flow direction (11) of the current in the main conductor, as primary conductor of the current converter. Connecting thighs (12, 13) are provided, outgoing from the centrepiece, and a supporting foot part (14; 15) is provided for each connecting thigh. The foot parts of both connecting thighs are fastened mechanically and electrically conducting on support surfaces (17) on the main current conductor, which are arranged in a distance to each other on one of the broadsides, in the flow direction of the current.
