It ships as a pre-assembled unit containing the contactor (3RT2026-1AP00), the link module (3RA2921-1AA00), and the busbar adapter (8US1251-5NT10). The overload release is thermal bimetallic, Class 10 trip class, meaning it protects motors with a normal starting profile — think conveyors, pumps, fans that reach full speed within ten seconds. The main circuit termination is screw-type, so you're wiring with ring or fork terminals, not spring cages. ## Motor power and mounting fit The frame size is S0 — the same as the supplied circuit-breaker — so the whole feeder fits in a consistent footprint on the busbar. Mounting is vertical only, with 50 mm clearance needed above, 32 mm in front, and 10 mm at the sides and below. No clearance required behind the unit. The 155 mm depth, 90 mm width, and 260 mm height let you plan the busbar layout without surprises. ## Lifecycle and sourcing The operating temperature range is -20 to +60 °C, with storage and transport limits of -50 to +80 °C. The 50/60 Hz operating frequency covers standard mains supplies globally.","metaTitle":"Siemens 3RA2220-4AD26-0AP0 SIRIUS Reversing Starter, S0","metaDescription":"Siemens 3RA2220-4AD26-0AP0 SIRIUS reversing starter, size S0, 7.5 kW at 400 V, Class 10 thermal overload, snaps onto 60 mm busbars.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Starters"],"specifications":{"Depth":"155 mm","Width":"90 mm","Height":"260 mm","Upwards":"50 mm","Forwards":"32 mm","Backwards":"0 mm","Downwards":"10 mm","Trip Class":"CLASS 10","At The Side":"10 mm","Rated Value":"690 V","During Storage":"-50 ... +80 °C","lifecycle_stage":"current","During Operation":"-20 ... +60 °C","During Transport":"-50 ... +80 °C","Fastening Method":"for snapping onto 60 mm busbar systems","Mounting Position":"vertical","PROFIsafe protocol":"No","Product Brand Name":"SIRIUS","Type Of Assignment":"2","Product Designation":"Reversing starter","Size Of Load Feeder":"S0","PROFINET IO protocol":"No","at 400 V rated value":"7 500 W","at 480 V rated value":"14 A","at 50 Hz rated value":"230 ... 230 V","Design Of The Product":"for 60 mm busbars","For Main Current Circuit":"screw-type terminals","Temperature Compensation":"-20 ... +60 °C","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":"3RT2026-1AP00","Of The Supplied Link Module":"3RA2921-1AA00","Size Of The Circuit-Breaker":"S0","at AC-3 rated value maximum":"690 V","Substance Prohibitance (Date)":"10/01/2009","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":"8US1250-5AT10","Design Of The Short-Circuit Trip":"magnetic","Of The Supplied Circuit-Breakers":"3RV2021-4AA10","degree of protection NEMA rating":"other","For Auxiliary And Control Circuit":"screw-type terminals","Product Extension Auxiliary Switch":"Yes","Relative Humidity During Operation":"10 ... 95 %","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":"9.8 VA","protocol is supported AS-Interface protocol":"No","with high demand rate according to SN 31920":"73 %","shock resistance according to IEC 60068-2-27":"6g / 11 ms","Type Of Voltage Of The Control Supply Voltage":"AC","at 400 V according to IEC 60947-4-1 rated value":"150 000 A","operational current at AC-3 at 400 V rated value":"15.5 A","Mechanical Service Life (Switching Cycles) Of Contactor Typical":"10 000 000","insulation voltage with degree of pollution 3 at AC rated value":"690 V","Adjustable Current Response Value Current Of The Current-Dependent Overload Release":"10 ... 16 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/0bbccd3685141d1129d0bc810bc50a87.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=106990&mlfb=3RA2220-4AD26-0AP0","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RA2220-4AD26-0AP0/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 3RA2220-4AD26-0AP0 and get a price?","answer":"No stock-holding claim is made here — availability is verified per inquiry."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RA2220-4AD26-0AP0","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/3RA2220-4AD26-0AP0 when reusing this data.
