Product details

The coil is 24 VDC with spring-type terminals — no screwdriver needed for the control wiring, which speeds up panel assembly and reduces torque-verification steps during commissioning. Rated operating temperature spans -25 to +60 °C during operation, with storage range -55 to +80 °C, so it handles typical industrial enclosure ambient conditions without derating concerns in most indoor environments.

Mounting and Clearance

Mounting position is flexible: +/-180° rotation on a vertical surface, plus +/-22.5° tilt forward/backward. Minimum clearances around the contactor: 10 mm upward, 10 mm forward, 10 mm downward, 6 mm at the side. That 73 mm depth and 45 mm width let you pack multiple units on a DIN rail in a shallow enclosure. Wire termination accepts solid or stranded conductors 0.5 to 4 mm², or two conductors of the same cross-section per clamp — common for daisy-chaining control power.

Frequently asked questions

What wire sizes does the 3RT2017-2AK61 accept?

Solid or stranded conductors from 0.5 to 4 mm², or two conductors of the same cross-section per spring-type terminal.

Will 3RT2017-2AK61 drop into a panel specified for 3RT2016-1AG62 without rewiring?

Both are Size S00 with the same DIN-rail footprint, so mechanical fit is identical. However, coil voltage and terminal type differ — verify the coil supply and whether spring-type terminals match your existing wiring.
