The 24 V DC coil is supplied via the integrated link module (3RA2921-1BA00); the busbar adapter (3RA2922-1AA00) and the contactor (3RT2026-1BB40) are included as part of the assembly. This is a drop-in reversing solution — no separate interlock wiring or overload selection needed. ## Mounting and panel integration Snap-on fastening to 35 mm standard rail, vertical mounting position only. Dimensions: 90 mm wide, 130 mm deep, 265 mm tall. Clearance requirements: 30 mm upwards, 10 mm forwards, 10 mm downwards, 9 mm at the side, 0 mm backwards — the back of the unit sits flush against the mounting surface. The S0 frame size keeps the footprint compact for a reversing starter — expect it to occupy roughly the space of two S0 contactors side by side. ## Lifecycle and sourcing RoHS compliance date: 03/01/2017. Operating temperature range -20 to +60 °C, storage -50 to +80 °C, transport -55 to +80 °C. Pollution degree 3 (conductive pollution or dry non-conductive pollution that becomes conductive due to condensation).","metaTitle":"Siemens 3RA2225-4AB26-0BB4 SIRIUS Reversing Starter, S0","metaDescription":"Siemens 3RA2225-4AB26-0BB4 SIRIUS non-fused reversing motor starter, size S0, 7.5 kW at 400 V AC-3, Class 10 thermal overload.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Motor Starters"],"specifications":{"Depth":"130 mm","Width":"90 mm","title":"3RA2225-4AB26-0BB4","Height":"265 mm","Upwards":"30 mm","Forwards":"10 mm","Backwards":"0 mm","Downwards":"10 mm","Trip Class":"CLASS 10","At The Side":"9 mm","Rated Value":"24 V","description":"Combination Starter Reversing FLA Range 11-16A 3 Pole 24VDC Coil S0 Open Type 1NO <(>&<)> 1NC Aux","During Storage":"-50 ... +80 °C","lifecycle_stage":"current","During Operation":"-20 ... +60 °C","During Transport":"-55 ... +80 °C","Fastening Method":"snap-on fastening on 35 mm standard rail","Mounting Position":"vertical","Product Brand Name":"SIRIUS","Type Of Assignment":"2","Degree Of Pollution":"3","Product Designation":"non-fused motor starter 3RA2","Size Of Load Feeder":"S0","at 230 V rated value":"2 hp","at 400 V rated value":"7 500 W","at 480 V rated value":"15.2 A","at 500 V rated value":"7 500 W","at 600 V rated value":"12.2 A","Design Of The Product":"reversing starter","at 110/120 V rated value":"1 hp","at 200/208 V rated value":"3 hp","at 220/230 V rated value":"5 hp","at 460/480 V rated value":"10 hp","at 575/600 V rated value":"10 hp","Of The Supplied Contactor":"3RT2026-1BB40","For Main Contacts Stranded":"1 ... 10 mm², 2x (2.5 ... 6 mm²)","Of The Supplied Link Module":"3RA2921-1BA00","Size Of The Circuit-Breaker":"S0","at AC-3 rated value maximum":"690 V","Substance Prohibitance (Date)":"03/01/2017","Design Of The Overload Release":"thermal (bimetallic)","Of The Supplied Busbar Adapter":"3RA2922-1AA00","Design Of The Switching Contact":"electromechanical","Operating Frequency Rated Value":"50 ... 60 Hz","at AWG cables for main contacts":"2x (16 ... 12), 2x (14 ... 8)","of the supplied RH assembly kit":"3RA2923-1BB1","Design Of The Short-Circuit Trip":"magnetic","Of The Supplied Circuit-Breakers":"3RV2021-4AA15","Product Extension Auxiliary Switch":"Yes","holding power of magnet coil at DC":"5.9 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":"3","number of NO contacts for auxiliary contacts":"3","shock resistance according to IEC 60068-2-27":"6g / 11 ms","Of The Supplied Standard Mounting Rail Adapter":"3RA2922-1AA00","at 400 V according to IEC 60947-4-1 rated value":"153 000 A","at 500 V according to IEC 60947-4-1 rated value":"100 000 A","operational current at AC-3 at 400 V rated value":"15.5 A","Type Of Electrical Connection For Main Current Circuit":"screw-type terminals","Mechanical Service Life (Switching Cycles) Of Contactor Typical":"10 000 000","Response Value Current Of Instantaneous Short-Circuit Trip Unit":"208 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":"11 ... 16 A","Connectable Conductor Cross-Section For Main Contacts Finely Stranded With Core End Processing":"1 ... 6 mm²"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/e931dc03dbd47159bdc9753fac61af20.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=535705&mlfb=3RA2225-4AB26-0BB4"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RA2225-4AB26-0BB4","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/3RA2225-4AB26-0BB4 when reusing this data.
