It ships with the contactor 3RT2017-1BB42, the link module 3RA1921-1DA00, and the busbar adapter 8US1251-5DS10 — so the reversing pair and overload are pre-wired and mechanically interlocked out of the box. The overload release is thermal bimetallic, so ambient temperature shifts affect the trip curve — mounted vertically per specification, the self-heating from the motor current and the enclosure ambient both factor into the actual protection threshold. Operating range is -20 to +60 °C, with storage from -50 to +80 °C — the wider storage band matters if the starter sits in an unheated warehouse before panel integration. ## Mounting and panel fit — busbar snap-on, vertical only Fastening is by snapping onto 60 mm busbar systems — no DIN-rail adapter needed, but the busbar pitch must match the S00 footprint. Mounting position is vertical only; horizontal installation changes the thermal calibration of the bimetallic overload. Dimensions are 155.1 mm deep, 90 mm wide, 200 mm high. Clearance requirements: 20 mm upwards, 10 mm downwards, 9 mm at the side, and zero forwards or backwards — so it fits tight against the back panel or enclosure wall. ## Current production — sourcing and documentation The 24 V coil is standard for modern PLC-driven panels; the pollution degree 3 rating means it is rated for industrial environments with conductive dust or occasional condensation — no additional conformal coating required for most cabinet installations.","metaTitle":"Siemens 3RA2215-1KD17-2BB4 SIRIUS Reversing Motor Starter","metaDescription":"Siemens 3RA2215-1KD17-2BB4 SIRIUS reversing motor starter, size S00, 5.5 kW at 400 V, Class 10 thermal overload, 24 V coil.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Motor Starters"],"specifications":{"Depth":"155.1 mm","Width":"90 mm","title":"3RA2215-1KD17-2BB4","Height":"200 mm","Upwards":"20 mm","Forwards":"0 mm","Backwards":"0 mm","Downwards":"10 mm","Trip Class":"CLASS 10","At The Side":"9 mm","Rated Value":"24 V","description":"Fuseless motor starter Reversing operation 600VAC Size S00 9-12.5 Amp 24V DC screw connection For snapping onto 60 mm busbar systems Type of coordination 1 1NO+1NC (MSP) 1NC (per contactor)","During Storage":"-50 ... +80 °C","lifecycle_stage":"current","During Operation":"-20 ... +60 °C","During Transport":"-55 ... +80 °C","Fastening Method":"for snapping onto 60 mm busbar systems","Mounting Position":"vertical","Product Brand Name":"SIRIUS","Type Of Assignment":"1","Degree Of Pollution":"3","Product Designation":"non-fused motor starter 3RA2","Size Of Load Feeder":"S00","at 230 V rated value":"2 hp","at 400 V rated value":"5 500 W","at 480 V rated value":"11 A","at 500 V rated value":"7 500 W","at 600 V rated value":"11 A","Design Of The Product":"reversing starter","at 110/120 V rated value":"0.5 hp","at 200/208 V rated value":"3 hp","at 220/230 V rated value":"3 hp","at 460/480 V rated value":"7.5 hp","at 575/600 V rated value":"10 hp","Of The Supplied Contactor":"3RT2017-1BB42","For Main Contacts Stranded":"0.5 ... 4 mm², 2x (0.75 ... 2.5 mm²)","Of The Supplied Link Module":"3RA1921-1DA00","Size Of The Circuit-Breaker":"S00","at AC-3 rated value maximum":"690 V","Design Of The Overload Release":"thermal (bimetallic)","Of The Supplied Busbar Adapter":"8US1251-5DS10","Design Of The Switching Contact":"electromechanical","Operating Frequency Rated Value":"50 ... 60 Hz","at AWG cables for main contacts":"2x (20 ... 16), only for contactor 2x (18 ... 14), 2x 12","of the supplied RS assembly kit":"3RA2913-1DB1","Design Of The Short-Circuit Trip":"magnetic","Of The Supplied Circuit-Breakers":"3RV2011-1KA15","Product Extension Auxiliary Switch":"Yes","holding power of magnet coil at DC":"4 W","Surge Voltage Resistance Rated Value":"6 kV","Number Of Poles For Main Current Circuit":"3","Product Function Short Circuit Protection":"Yes","number of NC contacts for auxiliary contacts":"2","number of NO contacts for auxiliary contacts":"1","shock resistance according to IEC 60068-2-27":"6g / 11 ms","at 400 V according to IEC 60947-4-1 rated value":"153 000 A","operational current at AC-3 at 400 V rated value":"11.5 A","Type Of Electrical Connection For Main Current Circuit":"screw-type terminals","Mechanical Service Life (Switching Cycles) Of Contactor Typical":"30 000 000","Response Value Current Of Instantaneous Short-Circuit Trip Unit":"162.5 A","insulation voltage with degree of pollution 3 at AC rated value":"690 V","Adjustable Current Response Value Current Of The Current-Dependent Overload Release":"9 ... 12.5 A","Connectable Conductor Cross-Section For Main Contacts Finely Stranded With Core End Processing":"0.5 ... 2.5 mm²"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/d0a9785b7be3ab1ed7ad28f5184ffec2.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=188560&mlfb=3RA2215-1KD17-2BB4"},"ai":{"faq":[{"question":"Where can I buy 3RA2215-1KD17-2BB4 and get a price?","answer":"This part is sourced through authorized Siemens distribution and quoted to order."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RA2215-1KD17-2BB4","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/3RA2215-1KD17-2BB4 when reusing this data.
