This contactor is rated for motor switching in AC-2 duty at 5.5 kW at 400 V, and in AC-4 duty at 8.5 A at 400 V. The 45 mm width and 57.5 mm height fit the Size S00 footprint, with a depth of 72 mm. ## Switching Capacity and Coordination The 3RT1017-1KF41's switching capacity varies significantly with the DC coil voltage and load type. At 24 V rated value it switches 10 A, at 60 V rated value 2 A, at 110 V rated value 1 A, and at 220 V rated value 0.3 A — these are the DC-13 (solenoid) ratings for the auxiliary contacts. For the main contacts in AC-1 (resistive) duty, it handles 20 A with gL/gG fuses of 20 A for Type 2 coordination, or 35 A fuses for Type 1 coordination. The AC-3 motor rating is not explicitly listed in this evidence, but the AC-2 and AC-4 ratings provide the motor-switching envelope. The AC-2 rating of 5.5 kW at 400 V covers slip-ring motor starting, while the AC-4 rating of 8.5 A at 400 V covers plugging and inching duty. For standard squirrel-cage motors (AC-3), the 5.5 kW at 500/690 V gives a practical guide for 400 V circuits — expect around 4 kW at 400 V in AC-3, but verify against the motor full-load current. ## Integration Notes Side-by-side mounting is allowed — no spacing required between contactors. The Size S00 frame (45 mm wide) fits standard 45 mm DIN-rail slots. Screw-type terminals for both main and auxiliary circuits accept solid or stranded wire: 2x (0.5... 1.5 mm²) or 2x (0.75... 2.5 mm²), with a maximum of 2x (0.75... 4 mm²). For AWG, the auxiliary contacts accept 2x (20... 16), 2x (18... 14), or 1x 12 AWG. The integrated varistor on the 110 VDC coil suppresses the inductive kick when de-energizing — no external suppression diode needed. The coil power is a constant 2.3 W DC, so the control transformer only needs to supply that steady load.","metaTitle":"Siemens 3RT1017-1KF41 SIRIUS Contactor, 110 VDC Coil, Size S","metaDescription":"Siemens 3RT1017-1KF41 SIRIUS power contactor, size S00, 110 VDC coil with varistor.

The 3RT1017-1KF41 has a 110 VDC coil with an integrated varistor; the 1AP01 variant uses an AC coil. They are not drop-in interchangeable without rewiring the control circuit."},{"question":"What is the depth of the 3RT1017-1KF41?","answer":"The depth is 72 mm.

Electrically no — the 1KF41 uses a 110 VDC coil with an integrated varistor, while the 1AP01 uses an AC coil. The control circuit would need rewiring to supply DC instead of AC, and the varistor polarity must be observed."},{"question":"What compliance documentation does Siemens provide for the 3RT1017-1KF41?","answer":"The part is RoHS compliant with a substance prohibition date of 07/01/2006.
