The Siemens 3RT1017-1BM42 is a SIRIUS power contactor in the compact S00 frame, rated for 5.5 kW at 400 V in AC-3 duty — that's the switching category for standard squirrel-cage motors, so it handles starting and running currents for a motor load up to that power.
The screw-type terminals for the main circuit accept 2x (0.5 to 1.5 mm²) solid, 2x (0.75 to 2.5 mm²), or up to 2x 4 mm² stranded — covers most panel wiring without crimp lugs.
Size S00 frame, 45 mm wide, 57.5 mm high, 72 mm deep. Mounts on 35 mm DIN rail per EN 50022 via screw or snap-on. Side-by-side mounting allowed with 6 mm side clearance.
Screw-type terminals accept 2x (0.5 to 1.5 mm²) solid, 2x (0.75 to 2.5 mm²) stranded, or up to 2x (0.75 to 4 mm²) max stranded. AWG equivalents: 2x (20 to 16), 2x (18 to 14), 1x 12.
