Rated 750 W at 400 V (AC-3) and 1.1 kW at 500 V, with a maximum AC-3 switching voltage of 690 V. The reversing contactor interlock is mechanical and electrical — no external wiring needed between the forward and reverse contactors; the link module handles the interlocking logic. ## Snap-on mounting and panel clearance Snap-on fastening to a 35 mm standard DIN rail (EN 60715), vertical mounting position only. Dimensions are 90 mm wide × 120 mm deep × 265 mm high — the S0 frame width fits alongside S00 breakers in a mixed feeder panel. Clearance requirements: 30 mm above, 10 mm in front, 10 mm below, 9 mm at the sides, and 0 mm behind the rail — so the back of the unit sits flush against the mounting plate. Operating temperature range is -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) — suitable for industrial control panels without additional environmental sealing. RoHS compliance date is 03/01/2017 (substance prohibitance per EU RoHS). The unit carries the SIRIUS brand designation and is designed for IEC 60947-4-1 compliance for motor starters and contactors.","metaTitle":"Siemens 3RA2225-1CB23-0AK6 SIRIUS Reversing Motor Starter","metaDescription":"Siemens SIRIUS 3RA2225-1CB23-0AK6 non-fused reversing motor starter, size S0, Class 10 thermal overload, 750 W at 400 V, snap-on 35 mm DIN rail.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Motor Starters"],"specifications":{"Depth":"120 mm","Width":"90 mm","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":"690 V","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":"0.17 hp","at 400 V rated value":"750 W","at 480 V rated value":"2.15 A","at 50 Hz rated value":"88 ... 121 V","at 500 V rated value":"1 100 W","at 60 Hz rated value":"96 ... 132 V","at 600 V rated value":"2.24 A","Design Of The Product":"reversing starter","at 200/208 V rated value":"0.5 hp","at 220/230 V rated value":"0.5 hp","at 460/480 V rated value":"1 hp","at 575/600 V rated value":"1.5 hp","Of The Supplied Contactor":"3RT2023-1AK60","For Main Contacts Stranded":"1 ... 10 mm², 2x (2.5 ... 6 mm²)","Of The Supplied Link Module":"3RA2921-1AA00","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":"3RV2011-1CA15","Product Extension Auxiliary Switch":"Yes","Surge Voltage Resistance Rated Value":"6 kV","Number Of Poles For Main Current Circuit":"3","Product Function Short Circuit Protection":"Yes","apparent holding power of magnet coil at AC":"7.2 VA","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":"1.9 A","Type Of Electrical Connection For Main Current Circuit":"screw-type terminals","Inductive Power Factor With The Holding Power Of The Coil":"0.28","Mechanical Service Life (Switching Cycles) Of Contactor Typical":"10 000 000","Response Value Current Of Instantaneous Short-Circuit Trip Unit":"32.5 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":"1.8 ... 2.5 A","Connectable Conductor Cross-Section For Main Contacts Finely Stranded With Core End Processing":"1 ... 6 mm²"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/ae13b5686c7f75f26c70ba7147057147.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=241149&mlfb=3RA2225-1CB23-0AK6","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RA2225-1CB23-0AK6/alternatives.json"},"ai":{"faq":[{"question":"What is the rated power of 3RA2225-1CB23-0AK6 at 400 V?","answer":"At 500 V the rating increases to 1.1 kW."},{"question":"What clearance is needed around this starter in a panel?","answer":"Minimum clearance: 30 mm above, 10 mm in front, 10 mm below, 9 mm at the sides, and 0 mm behind the DIN rail.
