It snaps directly onto 60 mm busbar systems — no DIN rail adapter needed — saving panel space in reversing duty applications like conveyors, hoists, and door drives. At 400 V AC-3 duty the starter delivers 11 000 W (11 kW), with a rated current of 22 A at 480 V and 21.9 A at 600 V — these are the motor full-load current ceilings the thermal overload can protect. Horsepower ratings span from 1.5 hp at 110/120 V up to 20 hp at 575/600 V, covering common North American motor frames in a single S0 package. Rated insulation voltage is 690 V, and the pollution degree is 3 — suitable for industrial environments with conductive dust or condensation. ## Mounting and clearances — panel integration notes Mounting position is vertical only, with the following minimum clearances to adjacent components: 30 mm upwards, 10 mm forwards, 10 mm downwards, 9 mm at the side, and 0 mm backwards — critical for airflow and arc-fault containment in the panel. Dimensions are 155 mm deep, 90 mm wide, and 260 mm high — the S0 envelope fits standard 200 mm deep enclosures with room for wiring gutters.","metaTitle":"Siemens 3RA2220-4CD27-0AP6 SIRIUS reversing starter, S0","metaDescription":"Siemens 3RA2220-4CD27-0AP6 SIRIUS non-fused reversing motor starter, S0 size, 11 kW at 400 V, Class 10 thermal overload, snaps onto 60 mm busbar.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Motor Starters"],"specifications":{"Depth":"155 mm","Width":"90 mm","title":"3RA2220-4CD27-0AP6","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":"690 V","description":"Fuseless motor starter Reversing operation 600VAC Size S0 17-22A 220/240VAC 50/60HZ screw connection For snapping onto 60 mm busbar systems Type of coordination 2 IQ = 50 KA Also full fills type Of coordination 1 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":"3 hp","at 400 V rated value":"11 000 W","at 480 V rated value":"22 A","at 50 Hz rated value":"176 ... 242 V","at 500 V rated value":"11 000 W","at 60 Hz rated value":"192 ... 264 V","at 600 V rated value":"21.9 A","Design Of The Product":"reversing starter","at 110/120 V rated value":"1.5 hp","at 200/208 V rated value":"5 hp","at 220/230 V rated value":"7.5 hp","at 460/480 V rated value":"15 hp","at 575/600 V rated value":"20 hp","Of The Supplied Contactor":"3RT2027-1AP60","Of The Supplied Link Module":"3RA2921-1AA00","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":"8US1251-5NT10","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":"3RV2021-4CA10","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":"9.4 VA","number of NC contacts for auxiliary contacts":"2","number of NO contacts for auxiliary contacts":"2","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":"22 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 (Operating Cycles) Of Contactor Typical":"10 000 000","Response Value Current Of Instantaneous Short-Circuit Trip Unit":"286 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":"17 ... 22 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":41,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/eb1cf9f463fa90698fb505c527cb5d4c.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=292985&mlfb=3RA2220-4CD27-0AP6"},"ai":{"faq":[{"question":"What is the closest alternative to 3RA2220-4CD27-0AP6 in the SIRIUS family?","answer":"The 3RA2 series is the current non-fused reversing starter line; a functionally similar unit would require a different contactor/overload combination and panel re-layout."},{"question":"How can I order 3RA2220-4CD27-0AP6 or check availability?","answer":"Submit an RFQ for current pricing and lead-time confirmation — no stock-holding claim is made here."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RA2220-4CD27-0AP6","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/3RA2220-4CD27-0AP6 when reusing this data.
