Screw-type terminals on the main circuit accept solid or stranded conductors: 2x (2.5 … 50 mm²) or 1x (10 … 70 mm²) for the power path, and 2x (2.5 … 16 mm²) for the control/auxiliary circuit. The 176 mm depth and 70 mm width fit standard 8-module DIN-rail spacing — no overhang into adjacent device slots. Clearance requirements: 150 mm upwards and downwards, 30 mm at the sides, zero forwards or backwards.
