The Siemens 3RT1017-2BM41 is a SIRIUS power contactor in the Size S00 frame, rated for switching motor loads up to 5.5 kW at 500 V or 690 V (AC-3 duty). The 24 VDC coil draws 3.3 W holding power, and the main contacts are spring-loaded terminals accepting 2x (0.25 to 2.5 mm²) solid or stranded wire.
The AC-3 motor-switching rating of 5.5 kW at 500 V and 690 V tells you this contactor handles three-phase induction motors up to that power — common for small pumps, fans, and conveyors. For resistive loads (AC-1), the maximum operating current is 10 A at 400 V. The coil holds at 24 VDC nominal; the 3.3 W holding power means a standard 24 VDC power supply can drive multiple contactors without excessive load. Install it inside a panel with at least IP54 enclosure for washdown or outdoor environments.
The spring-loaded terminals accept 0.25 to 2.5 mm² (24 to 14 AWG) solid or stranded, with a strip length of about 8 mm. Side-by-side mounting is allowed, saving panel width. The Size S00 footprint (45 mm wide, 60 mm tall, 73 mm deep) fits standard 200 mm deep enclosures with room for wiring ducts.
