The Siemens 3RT2017-1AV02 is a SIRIUS power contactor in size S00, designed for switching motor loads in control panels. It mounts on a 35 mm DIN rail per DIN EN 60715, using either screw fixing or snap-on clips. The 24 VDC coil with screw-type terminals is the primary ordering distinction for this variant.
Key ratings and what they mean for fit
Rated operational current in AC-3 duty (motor switching) is the headline figure: at 400 V, the contactor is rated for 3 A, and at 230 V it carries a 2 hp motor load. AC-3 switching frequency maxes out at 750 operations per hour, while AC-4 (plugging/reversing) is limited to 250 per hour. The auxiliary switch is built in, so no separate add-on block is needed for basic signaling. Mechanical life is typical 30,000,000 operations, meaning the contactor outlasts most panel builds before a wear-out replacement. Operating temperature range is -25 to +60 °C, with storage from -55 to +80 °C — fine for most industrial enclosures.
DIN rail and panel integration
Width is 45 mm, depth 73 mm, height 58 mm. Clearance requirements: 10 mm upwards, 10 mm forwards, 10 mm downwards, and 6 mm at the sides. Mounting position allows +/-180° rotation on a vertical surface and +/-22.5° tilt forward/backward — useful when panel layout is tight. Wire terminations accept solid or stranded conductors from 0.5 to 4 mm², with dual-wire capability (2x 0.5...1.5 mm², 2x 0.75...2.5 mm², or 2x 4 mm²). The screw terminals on the magnet coil match the main contact termination style, simplifying the wireman's kit.
