What It Is and Where It Fits
The 3RT2017-1AP02-2AA0: It mounts via screw and snap-on onto a 35 mm DIN rail per DIN EN 60715, and can be installed hanging or on a horizontal surface. The S00 frame keeps the footprint compact — 45 mm wide, 58 mm tall, 73 mm deep — which matters when you're packing multiple contactors into a panel and watching the fill factor.
Key Ratings and What They Mean for the Build
The auxiliary contact is rated for 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 3 A at 400 V. That covers most PLC-level and relay interface voltages — the 24 V rating is the one you'll use most often in a standard control panel. The motor rating at 230 V is 2 hp, so it's sized for smaller three-phase motors like those on pumps or small conveyors. Switching frequency limits: 1 000 cycles/hour at AC-1 (resistive), 750 cycles/hour at AC-2 and AC-3 (motor starting/running), and 250 cycles/hour at AC-4 (plugging/inching). If your application involves frequent jogging or reversing, the AC-4 ceiling is the one that governs — don't spec it for a high-cycle inching station without accounting for that derating. Mechanical service life is 30 000 000 operations typical, which is high for a contactor this size — it reflects the SIRIUS design's durability in cyclic duty. Arcing time is 10–15 ms, and operating time at AC is 4–15 ms. Power loss is 0.25 W at both 50 Hz and 60 Hz, negligible for panel thermal budgeting.
Wiring and Clearance Notes
Main contacts accept solid or stranded wire from 0.5 to 4 mm², and the screw terminals can take two conductors per clamp: 2x (0.5–1.5 mm²), 2x (0.75–2.5 mm²), or 2x 4 mm². That's enough for most motor circuit branch wiring up to the contactor's rating. Minimum clearances around the contactor: 10 mm upwards, 10 mm forwards, 10 mm downwards, and 6 mm at the side. These aren't just suggestions — they're needed for arc dissipation and heat rise. In a dense panel, the 10 mm vertical clearance is often the tightest constraint. Operating temperature range is -25 to +60 °C, storage range is -55 to +80 °C. That covers most indoor industrial environments; if the panel sits near a furnace or in a hot climate, the +60 °C operating limit is the one to watch.
