Product details

It mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, saving panel space at 45 mm width and 58 mm height. The screw-type magnet coil terminals accept solid or stranded wire from 0.5 to 4 mm², with the auxiliary switch included for feedback or interlocking.

Rated switching frequency depends on the duty category: AC-1 (resistive loads) allows up to 1,000 operations per hour, while AC-3 (standard motor starting) and AC-3e both permit 750 ops/h. For heavy inrush like AC-4 (plugging/reversing), the rate drops to 250 ops/h. Coil arcing time runs 10–15 ms at AC; the solid-state switching in the coil circuit handles that without external suppression for most panels.

Mounting position is flexible: ±180° rotation on a vertical surface, plus ±22.5° tilt forward/backward. Minimum clearances to adjacent components: 10 mm upward, 10 mm forward, 10 mm downward, 6 mm at the side. That 73 mm depth includes the coil overhang — plan gland-plate depth accordingly if panel depth is tight. Operating temperature range is -25 to +60 °C; storage range extends from -55 to +80 °C.

Frequently asked questions

Where can I buy the 3RT2018-1AV02?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm commitment.

Will the 3RT2018-1AV02 drop into a panel designed for the 3RT2016-1AK22 without rewiring?

Both are S00 frame contactors with the same DIN-rail mounting footprint and screw terminals, so mechanical fit is identical. However, the 3RT2018-1AV02 uses a 24 VDC coil while the 3RT2016-1AK22 may use a different coil voltage — verify the coil rating on your panel schematic before installation.
