What It Is and Where It Fits
The Siemens 3RT2017-1AQ02 is a SIRIUS power contactor in Size S00, the smallest frame in the SIRIUS family, designed for switching motor loads and resistive loads in control panels. It mounts via screw and snap-on onto a 35 mm DIN rail per DIN EN 60715, making it a direct fit for standard industrial enclosures. The 45 mm width and 73 mm depth leave room for auxiliary contact blocks and overload relays alongside on the rail.
Key Ratings and What They Mean for Fit
The 24 VDC coil is terminated with screw-type terminals, a conventional choice that suits maintenance teams familiar with screwdriver terminations. The auxiliary contacts are rated for switching at various voltages: 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. These ratings define the maximum switching capability for pilot duty and signal-level loads; for example, the 10 A at 24 V covers most PLC digital outputs and relay coils in a 24 VDC control circuit. The contactor is rated for maximum operating cycles per hour by duty class: 1,000 cycles/h at AC-1 (resistive), 750 cycles/h at AC-2 and AC-3 (motor starting and running), and 250 cycles/h at AC-4 (plugging and inching). This means for a conveyor motor running under AC-3 duty, the contactor can be cycled up to 750 times per hour without exceeding thermal limits. The mechanical life is typical 30 million operations, indicating the contactor is built for high-cycle applications like packaging or material handling. Operating temperature range is -25 to +60 °C, with storage from -55 to +80 °C, covering most indoor panel environments. The mounting position allows ±180° rotation on a vertical surface and ±22.5° tilt forward/backward, giving flexibility for tight enclosures where the contactor must be oriented off-axis.
Wiring and Termination
The main and auxiliary terminals accept solid or stranded wire from 0.5 to 4 mm², with dual-wire capacity: 2×(0.5…1.5 mm²), 2×(0.75…2.5 mm²), or 2×4 mm². This covers common control wiring sizes in North American (AWG 20–12) and European (0.5–4 mm²) practice. The screw-type terminals on the coil are the same style, so one screwdriver handles all terminations on the device.
