It ships as a factory-assembled unit with the contactor (3RT2024-1BB40), link module (3RA2921-1BA00), and busbar adapter (8US1251-5NT10) included — no separate ordering or field wiring of the reversing interlock. ## Busbar snap-on and panel clearances Mounts by snapping onto 60 mm busbar systems — the fastening method is integral, no DIN rail adapter needed for the busbar mount. Dimensions: 165 mm deep, 90 mm wide, 260 mm high. Required clearances around the unit: 30 mm upward, 10 mm forward, 10 mm downward, 9 mm at the side, and 0 mm backward — the back face sits flush against the mounting surface. Mounting position is vertical only; operating temperature range is -20 to +60 °C, with storage from -50 to +80 °C. ## Current production — sourcing posture RoHS compliance date is March 1, 2017 — the starter meets the EU RoHS substance restrictions as of that date.","metaTitle":"Siemens 3RA2225-1FD24-0BB4 SIRIUS Reversing Starter, Size S0","metaDescription":"Siemens 3RA2225-1FD24-0BB4 SIRIUS non-fused reversing motor starter, Size S0, 4.8 A at 480 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":"165 mm","Width":"90 mm","title":"3RA2225-1FD24-0BB4","Height":"260 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":"Fuseless motor starter Reversing operation 600VAC Size S0 3.5-5A 24V DC screw connection For snapping onto 60 mm busbar systems Type of coordination 2 IQ = 150 KA Also full fills type Of coordination 1 1NO+1NC (MSP) 1NO+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":"2","Degree Of Pollution":"3","Product Designation":"non-fused motor starter 3RA2","Size Of Load Feeder":"S0","at 230 V rated value":"0.5 hp","at 400 V rated value":"1 500 W","at 480 V rated value":"4.8 A","at 500 V rated value":"2 200 W","at 600 V rated value":"4.55 A","Design Of The Product":"reversing starter","at 110/120 V rated value":"0.17 hp","at 200/208 V rated value":"1 hp","at 220/230 V rated value":"1 hp","at 460/480 V rated value":"3 hp","at 575/600 V rated value":"3 hp","Of The Supplied Contactor":"3RT2024-1BB40","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":"8US1251-5NT10","Design Of The Switching Contact":"electromechanical","Operating Frequency Rated Value":"50 ... 60 Hz","of the supplied RS assembly kit":"3RA2923-1DB1","Design Of The Short-Circuit Trip":"magnetic","Of The Supplied Circuit-Breakers":"3RV2011-1FA15","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","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":"3.6 A","Type Of Electrical Connection For Main Current Circuit":"screw-type terminals","Mechanical Service Life (Operating Cycles) Of Contactor Typical":"10 000 000","Response Value Current Of Instantaneous Short-Circuit Trip Unit":"65 A","insulation voltage with degree of pollution 3 at AC rated value":"690 V","Type Of Connectable Conductor Cross-Sections For Main Contacts Stranded":"1 ... 10 mm², 2x (2.5 ... 6 mm²)","Adjustable Current Response Value Current Of The Current-Dependent Overload Release":"3.5 ... 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,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/5c038deac8ac81a8bed010c72d121f51.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=346933&mlfb=3RA2225-1FD24-0BB4"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RA2225-1FD24-0BB4","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/3RA2225-1FD24-0BB4 when reusing this data.
