The AC-4 (reversing/inching) rating at 400 V is 8.5 A — important if the application requires frequent plugging or jogging. Auxiliary contact switching capacity is given at several voltages: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 0.3 A at 220 V DC, which governs what pilot loads it can handle directly. ## Mounting and integration into a panel Dimensions are 45 mm wide, 57.5 mm high, 72 mm deep — fits a standard 45 mm module slot. Terminals are screw-type for both main and auxiliary circuits; the main circuit accepts 2x (0.5…1.5 mm²), 2x (0.75…2.5 mm²), or max. 2x (0.75…4 mm²) solid/stranded, or 2x (20…16), 2x (18…14), 1x 12 AWG. For type of coordination 1 (no damage to the contactor under short circuit), the required fuse is gL/gG 35 A. For type of coordination 2 (limited damage permissible), the fuse is gL/gG 20 A. This matters when designing the branch circuit — the fuse size governs the SCCR contribution and the selectivity with upstream breakers. The 3RT1017-1HB42 carries no integrated overload relay; it is a bare contactor intended to be paired with a separate SIRIUS overload or motor starter.","metaTitle":"Siemens 3RT1017-1HB42 SIRIUS Contactor, 24 VDC Coil, 10 A AC","metaDescription":"Siemens SIRIUS 3RT1017-1HB42 power contactor, 24 VDC coil, 10 A AC-12, 5.5 kW at 400 V AC-3.

It will not directly replace the 3RT1017-1HB42 without re-rating the motor branch circuit and checking the coil supply (AC vs DC). The 3RT1017-1AD02 is a 24 VAC/DC coil variant of the same frame size and ratings — that is a closer functional match if the coil voltage is flexible."},{"question":"Will 3RT1017-1HB42 drop into a panel that was specified around 3RT1016-1BB42 without rewiring?","answer":"Both are Size S00 and share the same 45 mm width and DIN-rail footprint, so the mechanical fit is identical. The main difference is the coil: 3RT1017-1HB42 is 24 VDC only, while 3RT1016-1BB42 is 24 VAC/DC. If the control circuit supplies 24 VAC, the DC coil will not energize. Check the coil supply before swapping."},{"question":"What compliance documentation does this brand provide for 3RT1017-1HB42 (RoHS, REACH, UL, IEC)?","answer":"RoHS compliance is confirmed with a substance prohibition date of 01.07.2006. The part is designed per IEC standards (IEC 60947-4-1) and carries CE marking. UL and CSA listings are typical for SIRIUS contactors but are not explicitly confirmed in this record; verify with the manufacturer for specific project requirements."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT1017-1HB42","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RT1017-1HB42 when reusing this data.
