Siemens SIRIUS 3RT2017-1AH01 — Power Contactor, Size S00
The Siemens SIRIUS 3RT2017-1AH01 is a Size S00 power contactor designed for switching motor loads up to 2 hp at 230 V. It mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, fitting a 45 mm wide footprint. The contactor includes an auxiliary switch and uses screw-type terminals for the coil.
Duty Ratings and Switching Frequency
Switching frequency depends on the duty class: AC-1 (resistive) allows up to 1000 operations per hour, AC-2 and AC-3 (motor starting/running) allow 750 per hour, and AC-4 (plugging/inching) is limited to 250 per hour. The AC-3e rating also caps at 750 per hour. These limits reflect the thermal load on the contacts — exceeding them shortens electrical life.
Mechanical Endurance and Temperature Range
Mechanical endurance is rated at 30 million operations typical. Operating temperature spans -25 to +60 °C; storage range is -55 to +80 °C. The mounting position allows +/-180° rotation on a vertical surface and +/-22.5° tilt forward/backward.
Wiring and Clearances
Terminals accept solid or stranded wire: 0.5 to 4 mm² single, or 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and 2x 4 mm². Minimum clearances to adjacent components: 10 mm upward, 10 mm forward, 10 mm downward, 6 mm at the side. Depth is 73 mm, height 58 mm.
