It ships as a pre-assembled unit with three contactors: two 3RT2017-1BB41 and one 3RT2015-1BB41, plus the RS assembly kit 3RA2913-2BB1. The 24 VDC coil pulls 10 W during closing, and the assembly is rated for 7.5 kW at 400 V AC-3, 10.3 kW at 500 V, and 9.2 kW at 690 V — meaning it handles the full transition current for a motor up to that load class.
Snaps onto 35 mm DIN rail or screws to a backplate — the S00 footprint keeps it compact at 68 mm high, 135 mm wide, and 145 mm deep. Clearance around the assembly is 6 mm upwards, forwards, downwards, and to the side; zero clearance needed behind it. That tight envelope fits neatly into a standard motor control center bucket or small panel.
All connections are screw-type terminals — main circuit, auxiliary/control circuit, and magnet coil. The main circuit accepts 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² solid or stranded wire. For the auxiliary circuit, the same 2x (0.5 to 1.5 mm²) and 2x (0.75 to 2.5 mm²) ranges apply. No built-in auxiliary switch or bus communication module — this is a straight electromechanical assembly for hardwired control.
