What it is and what it does
The Siemens 3RT6017-1AH01 is a SIRIUS power contactor in the compact size S00 frame, built for switching motor loads in control panels. Screw-type terminals on the main circuit, snap-on mounting to 35 mm DIN rail per EN 50022. It's rated for AC-3 duty up to 690 V, with motor output ratings of 7.5 kW at 230 V, 13 kW at 400 V, and 22 kW at 690 V — all at 60 °C ambient, so no derating headache in a warm enclosure. Auxiliary contact ratings cover the usual control voltages: 6 A at 24 V, 10 A at 230 V, 3 A at 400 V, 1 A at 690 V. Mechanical life is 30 million operations typical, so it'll outlast the machine it's in. Pollution degree 3 means it's rated for industrial environments with conductive contamination.
Sourcing and lifecycle reality
RoHS compliance date is noted as May 1, 2012, so it meets the EU substance restrictions that matter for CE marking. No UL or CSA marks appear in the spec record, but the SIRIUS line typically carries them — verify the specific nameplate if your panel requires a listed device.
Panel fit and mounting
Size S00 footprint: 45 mm wide, 57.5 mm tall, 73 mm deep. Screw and snap-on onto 35 mm DIN rail per EN 50022. Mounting position is flexible — +/-180° rotation on a vertical surface, plus +/-22.5° tilt forward/backward. Side-by-side mounting is allowed, so you can pack several in a row without derating for heat buildup. Terminal capacity: accepts 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² solid or stranded. Minimum cross-section at 40 °C is 4 mm², at 60 °C it's 2.5 mm² — that's the thermal derating for the power path, not a wiring restriction.
How it compares to a sibling
The closest functional peer in the SIRIUS line is the 3RT1015-1AG61. Both are size S00 power contactors with screw terminals and similar AC-3 motor ratings. The 3RT6017-1AH01 is the standard-duty variant; the 3RT1015-1AG61 is the higher-performance version with a wider coil voltage range and slightly different auxiliary contact configuration. If your panel was wired for the 3RT1015-1AG61, the 3RT6017-1AH01 will drop into the same DIN rail footprint and same terminal pattern — no rewiring needed for the power circuit. The difference is in the coil pickup and dropout characteristics, so verify the control voltage matches your PLC output.
