Siemens 3RT2017-2AV01 — SIRIUS Size S00 Power Contactor
The Siemens 3RT2017-2AV01 is a SIRIUS-brand power contactor in the compact Size S00 frame, designed for switching motor loads and resistive circuits in industrial control panels. Its 24 VDC coil draws 0.25 A at both 50 Hz and 60 Hz, and the spring-type terminals on the coil accept 0.5 to 4 mm² solid or stranded wire — no screw torque to verify, just strip and insert. The contactor mounts via screw or snap-on onto a 35 mm DIN rail per DIN EN 60715, with a 45 mm width and 73 mm depth that fits standard panel layouts. Mounting position allows +/-180° rotation on a vertical surface and +/-22.5° tilt forward/backward, giving flexibility in tight enclosures. Rated for a 10 A switching current at 24 V, this contactor handles auxiliary loads, small motors, and control transformers within the Size S00 envelope. The operating temperature range of -25 to +60 °C covers most indoor panel environments, with storage from -55 to +80 °C.
Switching Duty and Mechanical Life
The 3RT2017-2AV01 is rated for different switching frequencies depending on the duty class: up to 1,000 operations per hour at AC-1 (resistive loads), 750 ops/h at AC-2 and AC-3 (slip-ring and squirrel-cage motors), and 250 ops/h at AC-4 (plugging/reversing duty). The AC-3e rating also sits at 750 ops/h. Typical mechanical life is 30 million operations. Arcing time spans 10 to 15 ms at AC, and the contactor includes an auxiliary switch for status feedback or interlocking. The main contact rating follows a 20 to 12 scale (likely the utilization category code).
Clearance and Wiring
When mounting multiple contactors side-by-side, maintain the specified clearances: 10 mm upwards, 10 mm forwards, 10 mm downwards, and 6 mm at the side. These gaps ensure adequate cooling and arc containment. The spring terminals accept 0.5 to 4 mm² solid or stranded wire, and up to 2x (0.5 to 4 mm²) per clamp for daisy-chaining.
