Rated at 12 A operational current in AC-3 duty at 400 V, it handles a 5.5 kW motor load — the AC-3 rating is the one that matters for squirrel-cage induction motors with starting currents up to 8x rated; the 12 A figure governs the actual motor FLA it can switch, not a resistive-heater curve. The coil is 24 V DC, which means it pulls in cleanly on a DC supply without the hum or dropout issues an AC coil can exhibit in low-voltage conditions; holding power is inherently lower than an AC coil, reducing heat inside the panel. Fastens by screw or snaps onto 35 mm DIN rail per DIN EN 50022 — the S00 footprint (90 mm wide, 67 mm tall, 72 mm deep) fits standard enclosure backplates and leaves room for an overload relay or auxiliary contact block alongside. ## Lifecycle status and sourcing reality The successor 3RA2317-8XB11-1BB4 is the direct drop-in replacement for new designs or BOM updates; it shares the same S00 frame, 24 V DC coil, AC-3 rating, and screw-terminal configuration.","metaTitle":"Siemens 3RA1317-8XB11-1BB4 Reversing Contactor","metaDescription":"Siemens SIRIUS 3RA1317-8XB11-1BB4 reversing contactor assembly, AC-3 5.5 kW/400 V, 12 A, Size S00, 24 V DC coil, screw terminals.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Motor Starters"],"specifications":{"Depth":"72 mm","Width":"90 mm","Height":"67 mm","lifecycle_stage":"current","Fastening Method":"screw and snap-on mounting onto 35 mm standard mounting rail according to DIN EN 50022","Product Function":"Reversing contactor","Size Of Contactor":"S00","at DC rated value":"24 V","Substance Prohibitance (Date)":"07/01/2006","protection class IP on the front":"IP20","Ambient Temperature During Operation":"-25 ... +60 °C","reference code according to IEC 81346-2":"Q","operating power at AC-3 at 400 V rated value":"5.5 kW","Type Of Voltage Of The Control Supply Voltage":"DC","operational current at AC-3 at 400 V rated value":"12 A","Type Of Electrical Connection For Main Current Circuit":"screw-type terminals","number of NC contacts for auxiliary contacts per direction of rotation":"0","number of NO contacts for auxiliary contacts per direction of rotation":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=158568&mlfb=3RA1317-8XB11-1BB4","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RA1317-8XB11-1BB4/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for 3RA1317-8XB11-1BB4?","answer":"The official replacement is the 3RA2317-8XB11-1BB4 from the SIRIUS 3RA2 series, which shares the same S00 frame size, 24 V DC coil, AC-3 5.5 kW/400 V rating, and screw terminals."},{"question":"What is the difference between 3RA1 and 3RA2 reversing contactors?","answer":"The 3RA2 series (e.g., 3RA2317-8XB11-1BB4) is the manufacturer's successor to the 3RA1 series, offering the same S00 frame size, ratings, and terminal configuration as the phased-out 3RA1317-8XB11-1BB4."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RA1317-8XB11-1BB4","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/3RA1317-8XB11-1BB4 when reusing this data.
