The kit includes three contactors: two 3RT2018-2BB41 units for the line and star legs, plus one 3RT2016-2BB41 for the delta leg, all wired to an RS assembly kit 3RA2913-2BB2. No holes in the box — the spring-type terminals on both main and control circuits mean the panel wireman lands the motor leads and coil supply directly without crimping ferrules on solid wire. ## Motor power and coil — the ratings that decide fit The magnet coil pulls 24 VDC with a closing power of 10 W — a standard PLC-level control signal, no separate control transformer needed. Fuse sizing for type 2 coordination calls for 25 A gG NH 3NA, DIAZED 5SB, or NEOZED 5SE fuses. ## Panel fit and mounting flexibility Size S00 frame, 135 mm wide by 145 mm deep by 84 mm tall. Fastens with screws or snaps onto 35 mm DIN rail. Clearance around the unit: 6 mm upwards, forwards, downwards, and to the side; 0 mm backwards against the mounting surface. ## Environmental and mechanical endurance Mechanical life is 10 million operating cycles typical. Shock resistance at 11.4 g for 5 ms and 7.3 g for 10 ms on both AC and DC — rated for industrial floor vibration. Maximum AC-3 switching rate is 1,000 operations per hour, so it handles frequent start-stop cycles on conveyors or pumps without derating. ## Wiring terminals — spring-loaded, no tools needed Main current circuit and auxiliary/control circuit both use spring-loaded terminals. No screwdriver torque check — push the conductor in until the spring seats. The instant-contact design (3 instantaneous contacts) means no auxiliary switch block is fitted; if you need feedback to the PLC, add one externally. ## Compliance and substance restrictions No bus communication function on this variant — it's a standalone electromechanical assembly, not a fieldbus node.","metaTitle":"Siemens 3RA2417-8XF31-2BB4 SIRIUS Star-Delta Starter, 11 kW","metaDescription":"Siemens 3RA2417-8XF31-2BB4 SIRIUS contactor assembly for star-delta starting. 11 kW at 400 V AC-3, 24 VDC coil, spring terminals.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Starters"],"specifications":{"Depth":"145 mm","Solid":"2x (0.5 ... 4 mm²)","Width":"135 mm","at AC":"11,4g / 5 ms, 7,3g / 10 ms","at DC":"11,4g / 5 ms, 7,3g / 10 ms","title":"3RA2417-8XF31-2BB4","Height":"84 mm","Upwards":"6 mm","Forwards":"6 mm","Backwards":"0 mm","Downwards":"6 mm","At The Side":"6 mm","description":"Contactor assembly for star-delta (wye-delta) start AC-3, 11 kW/400 V, 24 V DC 3-pole, Size S00 Spring-type terminal electrical and mechanical interlock 3 NO integrated","During Storage":"-55 ... +80 °C","Of Magnet Coil":"Spring-type terminals","at AC-3 maximum":"1 000 1/h","lifecycle_stage":"current","During Operation":"-25 ... +60 °C","Fastening Method":"screw and snap-on mounting onto 35 mm DIN rail","Mounting Position":"+/-180° rotation possible on vertical mounting surface; can be tilted forward and backward by +/- 22.5° on vertical mounting surface","Size Of Contactor":"S00","Solid Or Stranded":"2x (0.5 ... 2.5 mm²)","at DC rated value":"24 V","Product Brand Name":"SIRIUS","Product Designation":"Contactor assembly for star-delta (wye-delta) start","Of Contactor Typical":"10 000 000","at 400 V rated value":"11 kW","at 500 V rated value":"11 kW","at 690 V rated value":"11 kW","Instantaneous Contact":"3","For Main Current Circuit":"spring-loaded terminals","1 Of The Supplied Contactor":"3RT2018-2BB41","2 Of The Supplied Contactor":"3RT2018-2BB41","3 Of The Supplied Contactor":"3RT2016-2BB41","at AC-3 rated value maximum":"690 V","Substance Prohibitance (Date)":"10/01/2009","of the supplied RS assembly kit":"3RA2913-2BB2","For Auxiliary And Control Circuit":"spring-loaded terminals","Product Extension Auxiliary Switch":"No","Product Function Bus Communication":"No","With Type Of Assignment 2 Required":"gG NH 3NA, DIAZED 5SB, NEOZED 5SE: 25 A","closing power of magnet coil at DC":"10 W","holding power of magnet coil at DC":"10 W","At Contactor For Auxiliary Contacts":"Spring-type terminals","With Type Of Coordination 1 Required":"gG NH 3NA, DIAZED 5SB, NEOZED 5SE: 50 A","at AWG cables for auxiliary contacts":"2x (20 ... 14)","number of NC contacts for main contacts":"0","number of NO contacts for main contacts":"3","reference code according to IEC 81346-2":"Q","Finely Stranded With Core End Processing":"2x (0.5 ... 1.5 mm²)","Number Of Poles For Main Current Circuit":"3","Contact Reliability Of Auxiliary Contacts":"< 1 error per 100 million operating cycles","with low demand rate according to SN 31920":"40 %","Finely Stranded Without Core End Processing":"2x (0.5 ... 1.5 mm²)","protocol is supported AS-Interface protocol":"No","with high demand rate according to SN 31920":"75 %","Type Of Voltage Of The Control Supply Voltage":"DC","contact rating of auxiliary contacts according to UL":"A600 / Q600","Of The Supplied Function Module For Wye-Delta Circuits":"3RA2816-0EW20","Installation Altitude At Height Above Sea Level Maximum":"2 000 m","product function control circuit interface with IO link":"No","Of The Contactor With Added Auxiliary Switch Block Typical":"10 000 000","For Short-Circuit Protection Of The Auxiliary Switch Required":"fuse gG: 10 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/b1760d40db10d3a62992187a1137e519.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=27461&mlfb=3RA2417-8XF31-2BB4"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RA2417-8XF31-2BB4","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/3RA2417-8XF31-2BB4 when reusing this data.
