Product details

S00 frame, 24 V DC coil, screw terminals

Rated operating current hits 10 A at AC-12 (resistive loads) and 8.5 A at AC-4 (frequent starting/inching) at 400 V.

Coordination and wiring

For Type 1 coordination (no damage but may need contact replacement after a fault) the required fuse is gL/gG 35 A. This lets you match the protection scheme to your maintenance philosophy. Screw terminals accept solid or stranded conductors: 2x (0.5–1.5 mm²), 2x (0.75–2.5 mm²), or max 2x (0.75–4 mm²). AWG equivalents are 2x (20–16), 2x (18–14), or 1x 12. The IP20 finger-safe protection on the front and terminals means it's safe for open-panel work as long as the enclosure is locked.

Frequently asked questions

How do I get current pricing and availability for 3RT1017-1AW21?

Submit an RFQ through this listing. Pricing and stock are confirmed at quote time; the part is sourced through independent distribution channels.

Will 3RT1017-1AW21 drop into a panel that was specified around 3RT1016-1AR11 without rewiring?

Both are S00 frame contactors with the same DIN-rail mounting footprint and screw-terminal layout, so the mechanical fit is identical. The 3RT1017-1AW21 uses a 24 V DC coil; verify that the 3RT1016-1AR11 coil voltage matches your control circuit before swapping.
