It ships with three 3RT2024-1AG20 contactors and the 3RA2923-2BB1 RS assembly kit installed — you mount it as one unit. Rated motor power is 11 kW at 400 V, 50/60 Hz, stepping up to 15.6 kW at 500 V and 19 kW at 690 V. The coil is 110 V at 50 Hz or 60 Hz. Contactor frame size is S0 — the standard footprint for this power band. All three contactors are identical, which simplifies spares stocking. ## Mounting and wiring — panel fit Mounts on 35 mm DIN rail via screw or snap-on fastening. The assembly is 135 mm wide, 101 mm tall, and 171 mm deep — measure your backpanel clearance before committing. Clearance around the unit: 6 mm upwards, forwards, downwards, and sideways; 0 mm backwards (the back sits flat on the rail). AWG equivalents: 2x (16...12) or 2x (14...8). Coil and auxiliary/control terminals also use screw-type connections — no spring-cage option on this variant. ## Environmental and mechanical limits Shock resistance: 11.8g at 5 ms (AC) and 15g at 5 ms (DC). Mechanical life of the contactor is rated at 10,000,000 operating cycles typical. No auxiliary switch or bus communication module is included or available as a factory extension on this order code. RoHS compliance date reference is 10/01/2009 — the assembly meets the EU RoHS directive effective from that date. Because it's a factory-integrated assembly of standard SIRIUS components, the individual contactors (3RT2024-1AG20) and the RS kit (3RA2923-2BB1) are also available separately for field service or replacement.","metaTitle":"Siemens 3RA2423-8XF32-1AG2 SIRIUS Star-Delta Starter","metaDescription":"Siemens 3RA2423-8XF32-1AG2 SIRIUS star-delta contactor assembly, 11 kW at 400 V, 3x 3RT2024 contactors, screw terminals, current production, available to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Starters"],"specifications":{"Depth":"171 mm","Solid":"2x (1 ... 2.5 mm²), 2x (2.5 ... 10 mm²)","Width":"135 mm","at AC":"11,8g / 5 ms, 7,4g / 10 ms","at DC":"15g / 5 ms, 10g / 10 ms","title":"3RA2423-8XF32-1AG2","Height":"101 mm","Upwards":"6 mm","Forwards":"6 mm","at 50 Hz":"0.25","at 60 Hz":"0.28","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, 110 V AC 50/60 Hz, 3-pole, size S0 screw terminals electrical and mechanical interlock 3 NO + 3 NC integrated","During Storage":"-55 ... +80 °C","Of Magnet Coil":"Screw-type terminals","lifecycle_stage":"current","During Operation":"-25 ... +60 °C","Fastening Method":"screw and snap-on mounting onto 35 mm standard mounting 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":"S0","Solid Or Stranded":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²)","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 50 Hz rated value":"110 V","at 500 V rated value":"15.6 kW","at 60 Hz rated value":"110 V","at 690 V rated value":"19 kW","Instantaneous Contact":"3","For Main Current Circuit":"screw-type terminals","1 Of The Supplied Contactor":"3RT2024-1AG20","2 Of The Supplied Contactor":"3RT2024-1AG20","3 Of The Supplied Contactor":"3RT2024-1AG20","Substance Prohibitance (Date)":"10/01/2009","at AWG cables for main contacts":"2x (16 ... 12), 2x (14 ... 8)","of the supplied RS assembly kit":"3RA2923-2BB1","For Auxiliary And Control Circuit":"screw-type 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","At Contactor For Auxiliary Contacts":"Screw-type terminals","operating frequency at AC-3 maximum":"1 000 1/h","With Type Of Coordination 1 Required":"gG NH 3NA, DIAZED 5SB, NEOZED 5SE: 63 A","at AWG cables for auxiliary contacts":"2x (20 ... 16), 2x (18 ... 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), 2x (0.75 ... 2.5 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 %","protocol is supported AS-Interface protocol":"No","with high demand rate according to SN 31920":"75 %","Type Of Voltage Of The Control Supply Voltage":"AC","operating voltage at AC-3 rated value maximum":"690 V","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/918262e4c5449e47e92e81029a731d18.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=478335&mlfb=3RA2423-8XF32-1AG2"},"ai":{"faq":[{"question":"What motor power does this starter handle at 400 V?","answer":"Rated motor power is 11 kW at 400 V, 50/60 Hz."},{"question":"What contactors are inside this assembly?","answer":"It contains three Siemens 3RT2024-1AG20 contactors (size S0), all identical, plus the 3RA2923-2BB1 RS assembly kit."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RA2423-8XF32-1AG2","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/3RA2423-8XF32-1AG2 when reusing this data.
