The reversing design means forward/reverse control of a three-phase motor without an external interlock or separate contactor pair, saving panel space and wiring time. Size S0 load feeder — the physical frame that determines DIN-rail footprint and busbar compatibility across the SIRIUS family. Snaps onto a 35 mm standard rail (EN 60715) without tools. Mounting position is vertical only. ## 24 V control — what it means for panel integration Rated control voltage is 24 V (likely DC, standard for industrial PLC cabinets). The starter draws its coil power from the 24 V bus — no separate AC control transformer needed. Main contact wiring accepts stranded conductors 1–10 mm² (single) or 2 × 2.5–6 mm² (two per terminal). This covers most motor feeder sizes up to the starter's rating. ## Motor power ratings across common voltages At 400 V the rating is 1 100 W; at 500 V it is 1 500 W. Current ratings at 480 V and 600 V are 2.8 A and 3.16 A respectively (AC-3 duty). This covers small pumps, fans, conveyors, and machine-tool spindles up to 2 hp. Maximum AC-3 rated voltage is 690 V — the contactor's insulation and arc-chamber design handle line-to-line up to that level, though the motor power ratings top out at 600 V. ## Physical dimensions — panel layout fit Depth 130 mm, width 90 mm, height 265 mm. The DIN-rail clip adds 30 mm upwards clearance and 10 mm forwards clearance; no backwards clearance needed. Side clearance is 9 mm. These numbers decide the gland-plate fill and the minimum enclosure depth for a 35 mm rail profile. ## Environmental and compliance Operating temperature range –20 to +60 °C; storage –50 to +80 °C; transport –55 to +80 °C. Degree of pollution 3 (conductive pollution or dry non-conductive that becomes conductive — typical for industrial control panels without sealed enclosures). RoHS compliance with a substance prohibitance date of 03/01/2017.","metaTitle":"Siemens 3RA2225-1DB23-0BB4 SIRIUS Motor Starter, Reversing","metaDescription":"Siemens 3RA2225-1DB23-0BB4 SIRIUS non-fused reversing motor starter, 24 V control, Size S0, 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":"3RA2225-1DB23-0BB4","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 2.2-3.2A 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":"0.25 hp","at 400 V rated value":"1 100 W","at 480 V rated value":"2.8 A","at 500 V rated value":"1 500 W","at 600 V rated value":"3.16 A","Design Of The Product":"reversing starter","at 110/120 V rated value":"0.1 hp","at 200/208 V rated value":"0.5 hp","at 220/230 V rated value":"0.75 hp","at 460/480 V rated value":"1.5 hp","at 575/600 V rated value":"2 hp","Of The Supplied Contactor":"3RT2023-1BB40","For Main Contacts Stranded":"1 ... 10 mm², 2x (2.5 ... 6 mm²)","Of The Supplied Link Module":"3RA2921-1BA00","Size Of The Circuit-Breaker":"S00","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":"3RV2011-1DA15","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","operational current at AC-3 at 400 V rated value":"2.7 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":"41.6 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":"2.2 ... 3.2 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/d1ffd0344f27334eb740ae828971d1bc.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=248691&mlfb=3RA2225-1DB23-0BB4"},"ai":{"faq":[{"question":"What motor sizes does this reversing starter cover?","answer":"Trip Class 10 thermal overload protects standard induction motors."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RA2225-1DB23-0BB4","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/3RA2225-1DB23-0BB4 when reusing this data.
