This is a hardwired reversing starter — no PROFIsafe or PROFINET IO onboard. It's designed for conventional control circuits where a PLC or relay logic toggles the direction contactors, not for networked safety drives. The supplied sub-assemblies are pre-integrated: a 3RT2024-2AP00 contactor, a 3RA2921-2AA00 link module, and an 8US1251-5NT11 busbar adapter. No separate ordering for these components. ## Motor power ratings across common voltages At 400 V, the rated motor power is 4 kW. At 460/480 V, it's 5 hp. At 575/600 V, it's 7.5 hp. For 200/208 V, it's 2 hp, and at 220/230 V, it's 3 hp. The rated current at 480 V is 7.6 A. This is standard for general-purpose motor starting; Class 10 is faster than Class 20, so it protects motors with shorter locked-rotor withstand times. Rated insulation voltage is 690 V, and the maximum AC-3 operating voltage is also 690 V — the starter's internal clearances handle 690 V line-to-line without derating. ## Panel layout and busbar snap-on The envelope is 260 mm high, 90 mm wide, 165 mm deep. Mounting position is vertical only. Fastening is by snapping onto 60 mm busbar systems — no DIN rail adapter required, but the busbar pitch must match. Clearance spacings: 50 mm upwards, 32 mm forwards, 10 mm downwards, 10 mm at the side, 0 mm backwards. These are the minimum free air gaps for heat dissipation and arc flash containment — don't crowd the top or front. Main circuit wiring uses spring-loaded terminals — no screw torque to verify, just strip and push. This speeds panel wiring but requires a ferrule for stranded wire to prevent strand fanning. ## Thermal limits and storage range Operating ambient temperature range is -20 to +60 °C with temperature compensation active across that span. Storage and transport range is -50 to +80 °C — the starter can sit in an unheated warehouse through winter without damage. Substance prohibitance date 03/01/2017 aligns with RoHS compliance — no restricted substances above threshold for EU market placement.","metaTitle":"Siemens 3RA2220-1JH24-0AP0 SIRIUS Reversing Starter, S0","metaDescription":"Siemens 3RA2220-1JH24-0AP0 SIRIUS reversing starter, Size S0, 4 kW at 400 V, Trip Class 10, spring terminals, 60 mm busbar snap-on.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Starters"],"specifications":{"Depth":"165 mm","Width":"90 mm","title":"3RA2220-1JH24-0AP0","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","description":"Load feeder fuseless, Reversing duty 400 V AC, Size S0 7.00...10.0 A 230 V AC Spring-type terminal for 60 mm busbar systems (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":"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":"4 000 W","at 480 V rated value":"7.6 A","at 50 Hz rated value":"230 ... 230 V","Design Of The Product":"for 60 mm busbars","For Main Current Circuit":"spring-loaded terminals","Temperature Compensation":"-20 ... +60 °C","at 200/208 V rated value":"2 hp","at 220/230 V rated value":"3 hp","at 460/480 V rated value":"5 hp","at 575/600 V rated value":"7.5 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)","Of The Supplied Busbar Adapter":"8US1251-5NT11","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":"3RV2021-1JA20","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":"8.5 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":"7 ... 10 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/223cce7a11c3391a57ac8f7130c10aa8.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=86977&mlfb=3RA2220-1JH24-0AP0"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RA2220-1JH24-0AP0","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/3RA2220-1JH24-0AP0 when reusing this data.
