Product details

SIRIUS Size S00 Power Contactor, 110 VDC Coil

It carries a 110 VDC coil with an integrated varistor for surge suppression, and its screw-type terminals accept wire sizes from 2x (0.5... 1.5 mm²) solid up to 2x (0.75... 4 mm²) stranded, with a maximum of 2x (0.75... 4 mm²). 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.

Frequently asked questions

What is the closest functional second-source to the 3RT1017-1KF41?

The closest functional peer is the 3RT1017-1AP01, which shares the same Size S00 frame and screw-type terminals but uses a different coil voltage (AC, not 110 VDC). 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.

What is the depth of the 3RT1017-1KF41?

The depth is 72 mm. The overall dimensions are 45 mm width, 57.5 mm height, and 72 mm depth for the Size S00 frame.

What wire sizes does the 3RT1017-1KF41 accept?

The screw-type terminals accept solid or stranded wire: 2x (0.5... 1.5 mm²), 2x (0.75... 2.5 mm²), and a maximum of 2x (0.75... 4 mm²). For AWG, the auxiliary contacts accept 2x (20... 16), 2x (18... 14), or 1x 12 AWG.

Will the 3RT1017-1KF41 drop into a panel specified for the 3RT1017-1AP01?

Mechanically yes — both are Size S00 with the same 45 mm width and DIN-rail mounting. 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.

What compliance documentation does Siemens provide for the 3RT1017-1KF41?

The part is RoHS compliant with a substance prohibition date of 07/01/2006. It is rated for pollution degree 3 per IEC 60947-1. The IP20 rating on front and terminals indicates finger-safe construction. Standard Siemens declarations of conformity (CE, UKCA) and UL/CSA listings apply to the SIRIUS contactor family, though specific certification marks are not listed in this evidence.
