Snap-on mounting on 35 mm standard rail, vertical position only — the thermal bimetallic overload (CLASS 10 trip class) is calibrated for vertical orientation; laying it flat shifts the trip curve. Footprint is 120 mm deep by 90 mm wide by 265 mm tall — the S0 frame keeps the gland-plate fill factor manageable in a 600 mm wide enclosure. Rated 690 V insulation voltage, AC-3 switching duty up to 690 V — covers 400 V, 480 V, 575 V, and 600 V line supplies without derating the voltage class. ## Power ratings across common line voltages At 400 V the starter is rated 550 W; at 460/480 V it delivers 0.75 hp; at 575/600 V also 0.75 hp — the motor full-load current at 480 V is 1.6 A, at 600 V it is 1.3 A. At 690 V the rating climbs to 1 100 W — useful for 690 V mining or marine distribution where the step-down transformer is upstream of the MCC. The supplied contactor is 3RT2023-1AK60; the link module is 3RA2921-1AA00; the busbar adapter is 3RA2922-1AA00 — all three are included, so no separate ordering for the reversing interlock hardware. ## Thermal environment and pollution class Operating ambient range is -20 to +60 °C — the bimetallic overload compensates across this band, but above 40 °C the trip current setting should be derated per the IEC 60947-4-1 derating curve. Pollution degree 3 means the unit is rated for conductive contamination (condensation, light dust) typical of industrial control panels without a sealed enclosure — no conformal coating required for the internal clearances. Storage range -50 to +80 °C and transport range -55 to +80 °C — the starter can sit in an unheated warehouse or ship in a non-climate-controlled truck without damage. ## Lifecycle and compliance — current production, RoHS dated RoHS compliance date is 03/01/2017 — the substance prohibition per EU Directive 2011/65/EU is met; no REACH SVHC declaration is in this record, but the RoHS date covers the standard industrial exemption set. The supplied sub-assemblies (contactor, link module, busbar adapter) are all current-production SIRIUS catalog items — no orphaned parts inside the assembly.","metaTitle":"Siemens 3RA2225-1AB23-0AK6 SIRIUS Reversing Motor Starter","metaDescription":"Siemens 3RA2225-1AB23-0AK6 SIRIUS non-fused reversing motor starter, size S0, CLASS 10 thermal overload, 690 V AC-3, 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":"0.1 hp","at 400 V rated value":"550 W","at 480 V rated value":"1.6 A","at 50 Hz rated value":"88 ... 121 V","at 500 V rated value":"550 W","at 60 Hz rated value":"96 ... 132 V","at 600 V rated value":"1.3 A","at 690 V rated value":"1 100 W","Design Of The Product":"reversing starter","at 460/480 V rated value":"0.75 hp","at 575/600 V rated value":"0.75 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":"3RV2011-1AA15","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":"1.5 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":"20.8 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":"1.1 ... 1.6 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/c86a8f3a5512671ca2bfca77a610dda8.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=314957&mlfb=3RA2225-1AB23-0AK6","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RA2225-1AB23-0AK6/alternatives.json"},"ai":{"faq":[{"question":"What is the CLASS 10 trip class mean for motor protection?","answer":"This protects standard induction motors during start-up without nuisance tripping on normal acceleration, but it is not suitable for high-inertia loads that need CLASS 20 or CLASS 30."},{"question":"What compliance documentation does Siemens provide for this motor starter?","answer":"The RoHS compliance date is 03/01/2017, covering EU Directive 2011/65/EU.
