The Class 10 trip characteristic protects standard squirrel-cage motors during start-up — the overload relay allows a 10-second thermal lockout at locked-rotor current before tripping, matching the acceleration time of most general-purpose pumps and fans. ## Mounting and enclosure fit — DIN rail clearances Mounts on a 35 mm standard DIN rail via the supplied adapter, or screws directly to a backplate. The vertical mounting position is mandatory for the bimetallic overload to track ambient temperature correctly. Envelope is 90 mm wide, 130 mm deep, 269 mm tall. Clearance requirements: 50 mm above, 32 mm in front, 10 mm at the sides, 10 mm below — no space needed behind the rail. These clearances govern the DIN-rail segment pitch in a crowded panel; a 90 mm wide starter needs at least 110 mm of rail width per unit when side clearances are shared. ## Duty ratings and operating envelope Maximum AC-3 switching voltage is 690 V. Operating frequency is 50/60 Hz; the thermal overload is temperature-compensated across -20 to +60 °C ambient. Storage and transport limits are -50 to +80 °C. Substance prohibitance (RoHS compliance) dated 03/01/2017 — the starter meets EU RoHS requirements for that effective date. ## Lifecycle and sourcing — current production, quoted to order Sourced through independent distribution against an RFQ.","metaTitle":"Siemens 3RA2220-1HF24-0AP0 SIRIUS Reversing Starter, S0","metaDescription":"Siemens 3RA2220-1HF24-0AP0 SIRIUS reversing starter, size S0, 3 kW at 400 V AC-3, Class 10 thermal overload, spring-loaded terminals, DIN rail mount.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Starters"],"specifications":{"Depth":"130 mm","Width":"90 mm","title":"3RA2220-1HF24-0AP0","Height":"269 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","description":"Load feeder fuseless, Reversing duty 400 V AC, Size S0 5.50...8.00 A 230 V AC Spring-type terminal for installation on standard mounting rail with standard mounting rail adapter (also fulfills type of coordination 1) Type of coordination 2, Iq = 150 kA 1 NO+1 NC (contactor)","During Storage":"-50 ... +80 °C","lifecycle_stage":"current","During Operation":"-20 ... +60 °C","During Transport":"-50 ... +80 °C","Fastening Method":"On adapter for screw and snap-on mounting on 35 mm standard mounting rail","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":"3 000 W","at 480 V rated value":"8 A","at 50 Hz rated value":"230 ... 230 V","Design Of The Product":"for standard rail or screw mounting","For Main Current Circuit":"spring-loaded terminals","Temperature Compensation":"-20 ... +60 °C","at 220/230 V rated value":"2 hp","at 460/480 V rated value":"5 hp","at 575/600 V rated value":"5 hp","Of The Supplied Contactor":"3RT2024-2AP00","Of The Supplied Link Module":"3RA2921-2AA00","Size Of The Circuit-Breaker":"S0","at AC-3 rated value maximum":"690 V","Substance Prohibitance (Date)":"03/01/2017","Design Of The Overload Release":"thermal (bimetallic)","Design Of The Switching Contact":"electromechanical","Operating Frequency Rated Value":"50 ... 60 Hz","of the supplied RH assembly kit":"3RA2923-1BB2","Design Of The Short-Circuit Trip":"magnetic","Of The Supplied Circuit-Breakers":"3RV2021-1HA20","degree of protection NEMA rating":"other","For Auxiliary And Control Circuit":"spring-loaded 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":"8.5 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":"6.5 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":"5.5 ... 8 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/05c23b368ca3e3e323b613cc6e5f8b0d.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=171902&mlfb=3RA2220-1HF24-0AP0"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RA2220-1HF24-0AP0","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/3RA2220-1HF24-0AP0 when reusing this data.
