Product details

Product Overview

The Siemens 3RT2518-1AF00 is a SIRIUS contactor in the compact S00 frame size, rated for 10 A at 24 VDC and fitted with screw-type terminals.

The S00 frame keeps the width to 45 mm, height 57.5 mm, and depth 73 mm, allowing dense packing on the DIN rail. Wiring terminals accept solid or stranded conductors: 2x (0.5... 1.5 mm²), 2x (0.75... 2.5 mm²), or 2x 4 mm². This covers typical control wiring from signal-level to moderate power feeds without needing adapters. Operating temperature range is -25 to +60 °C, with storage from -55 to +80 °C. The contactor can be mounted in any orientation, including +/-180° rotation on a vertical surface and +/-22.5° tilt forward/backward, which simplifies panel layout.

Frequently asked questions

What are the key dimensions for panel layout?

Width is 45 mm, height 57.5 mm, and depth 73 mm. It mounts on 35 mm DIN rail per DIN EN 50022.

What wire sizes does the screw terminal accept?

The screw-type terminals accept 2x (0.5... 1.5 mm²), 2x (0.75... 2.5 mm²), or 2x 4 mm² solid or stranded conductors.
