The 3RT1017-1AP01: The headline numbers to check against your BOM: the 24 VDC coil draws 10 A, and the main poles are rated for AC-4 at 8.5 A / 400 V — that's the switching current for frequent starts and reversals, not just continuous running. The contactor also lists a mechanical life of 30 million operations, which is typical for this frame size and indicates a robust mechanism for high-cycle applications.
Width is 45 mm, depth 72 mm, height 57.5 mm — fits standard S00 footprint. Wire range for main contacts: solid/stranded 2x (0.5–1.5 mm²), 2x (0.75–2.5 mm²), max 2x (0.75–4 mm²); AWG equivalent 2x (20–16), 2x (18–14), 1x 12. Auxiliary contacts share the same AWG range.
For type 1 coordination (contactor may need replacement after fault), use gL/gG 35 A. The contactor is rated for 50 Hz and 60 Hz operation with operating ranges of 0.8–1.1 and 0.85–1.1 times rated voltage respectively.
