SIRIUS 3RT2017-2AP61 — Size S00 Power Contactor with 24 VDC Coil
The Siemens 3RT2017-2AP61 is a SIRIUS-brand power contactor in the compact Size S00 frame, designed for switching motor loads and resistive circuits in industrial control panels. It carries a 24 VDC coil with spring-type terminals for the magnet coil, and its main contacts are rated for AC-3 duty at up to 750 operating cycles per hour. The 45 mm wide body snaps onto 35 mm DIN rail per DIN EN 60715, making it a direct fit for standard panel layouts.
What the Ratings Mean for Your Panel
The Size S00 frame keeps the contactor footprint tight — 73 mm deep, 45 mm wide, 70 mm tall — so it fits densely packed DIN-rail assemblies without crowding adjacent devices. The spring-type coil terminals accept solid or stranded wire from 0.5 to 4 mm², and the same gauge range applies to the main contact wiring (2x 0.5 to 4 mm² per terminal). This means you can land standard 14–10 AWG control wiring without lug adapters. Switching frequency limits are specified per duty class: AC-1 (resistive) allows up to 1,000 cycles/hour, AC-2 and AC-3 (motor starting/running) cap at 750 cycles/hour, and AC-4 (plugging/reversing) drops to 250 cycles/hour. For a conveyor drive cycling every 5 seconds, the AC-3 rate is adequate; for a rapid-reversing application like a tapping machine, the AC-4 limit governs the real duty cycle. The contactor operates across -25 to +60 °C ambient and can be mounted in any orientation within ±180° rotation and ±22.5° tilt on a vertical surface. Clearance requirements are minimal: 10 mm upward, 10 mm forward, 10 mm downward, and 6 mm at the side — useful when fitting into a crowded sub-panel.
Panel Integration Notes
Mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715. The spring-type terminals for the coil and main contacts reduce wiring time compared to screw-clamp variants — no torque driver needed, just strip to 8–10 mm and insert. The auxiliary switch is built in (yes), so no separate add-on block is required for basic status feedback. Arcing time is 10 to 15 ms at AC, and the mechanical life of the contactor is rated at 30,000,000 typical operations — meaning the coil and armature assembly will outlast the electrical contact wear in most motor-switching applications.
