Siemens 3RT2017-1AN21 SIRIUS Power Contactor – Size S00, 24 VDC Coil
It mounts via screw and snap-on onto 35 mm DIN rail per DIN EN 60715, and the mounting position allows +/-180° rotation on a vertical surface plus +/-22.5° tilt forward/backward, giving panel builders flexibility in tight enclosures. Rated for AC-3 duty at 750 switching cycles per hour maximum, this contactor handles the repetitive start/stop of squirrel-cage motors typical in conveyor, pump, and fan applications. The AC-1 resistive load rating allows up to 1000 cycles per hour for heating or lighting loads.
At 45 mm wide, 58 mm tall, and 73 mm deep, the S00 frame fits standard DIN-rail spacing. The auxiliary switch is included, with ratings from 10 A at 24 V down to 0.2 A at 440 V — verify the control voltage for your specific signal circuit. Arcing time is 10 to 15 ms at AC, and the main contacts are sized for wire cross-sections from 20 to 12 AWG (0.5 to 4 mm²). Mechanical life is typical 30 million operations.
