It combines a reversing contactor pair, a thermal bimetallic overload relay (Class 10 trip class), and a magnetic short-circuit trip in a single, pre-wired unit that snaps onto a 35 mm standard DIN rail. ## Rated motor power and control voltage — what drives the fit The motor power rating is voltage-dependent: 180 W at 400 V, 250 W at 500 V, and 370 W at 690 V. The control circuit accepts 88–121 V at 50 Hz or 96–132 V at 60 Hz — a common range for 110 V control transformers in European panels. ## Thermal overload and short-circuit coordination The short-circuit release is magnetic, providing instantaneous trip for fault currents. The supplied contactor (3RT2023-1AK60) and link module (3RA2921-1AA00) are coordinated for Type 2 coordination with the upstream circuit breaker (size S00), meaning the starter survives a short-circuit fault without damage to the contactor or overload relay. ## DIN rail mounting and panel clearances Snap-on fastening on 35 mm standard rail, vertical mounting position only. The footprint is 90 mm wide, 120 mm deep, and 265 mm tall. Required clearances for airflow and wiring: 30 mm upward, 10 mm forward, 10 mm downward, 9 mm at the sides, and 0 mm backward (flush to the rail). ## Conductor sizing and supplied accessories AWG equivalents are 2 × (16–12) or 2 × (14–8). The package includes the reversing contactor (3RT2023-1AK60), link module (3RA2921-1AA00), busbar adapter (3RA2922-1AA00), and an RH assembly kit (3RA2923-1BB1) — all pre-assembled for a single order code.","metaTitle":"Siemens 3RA2220-0HB23-0AK6 SIRIUS Reversing Starter","metaDescription":"Siemens 3RA2220-0HB23-0AK6 SIRIUS non-fused reversing motor starter, 180 W at 400 V, Class 10 thermal overload, snap-on DIN rail.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Motor Starters"],"specifications":{"Depth":"120 mm","Width":"90 mm","Height":"265 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","During Storage":"-50 ... +80 °C","lifecycle_stage":"current","During Operation":"-20 ... +60 °C","During Transport":"-55 ... +80 °C","Fastening Method":"snap-on fastening on 35 mm standard rail","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 400 V rated value":"180 W","at 50 Hz rated value":"88 ... 121 V","at 500 V rated value":"250 W","at 60 Hz rated value":"96 ... 132 V","at 690 V rated value":"370 W","Design Of The Product":"reversing starter","Of The Supplied Contactor":"3RT2023-1AK60","For Main Contacts Stranded":"1 ... 10 mm², 2x (2.5 ... 6 mm²)","Of The Supplied Link Module":"3RA2921-1AA00","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":"3RA2922-1AA00","Design Of The Switching Contact":"electromechanical","Operating Frequency Rated Value":"50 ... 60 Hz","at AWG cables for main contacts":"2x (16 ... 12), 2x (14 ... 8)","of the supplied RH assembly kit":"3RA2923-1BB1","Design Of The Short-Circuit Trip":"magnetic","Of The Supplied Circuit-Breakers":"3RV2011-0HA10","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":"7.2 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","Of The Supplied Standard Mounting Rail Adapter":"3RA2922-1AA00","at 400 V according to IEC 60947-4-1 rated value":"153 000 A","operational current at AC-3 at 400 V rated value":"0.6 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 (Switching Cycles) Of Contactor Typical":"10 000 000","Response Value Current Of Instantaneous Short-Circuit Trip Unit":"10.4 A","insulation voltage with degree of pollution 3 at AC rated value":"690 V","Adjustable Current Response Value Current Of The Current-Dependent Overload Release":"0.55 ... 0.8 A","Connectable Conductor Cross-Section For Main Contacts Finely Stranded With Core End Processing":"1 ... 6 mm²"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/c34c3f36ab38c8a5515d2e0a61611574.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=81114&mlfb=3RA2220-0HB23-0AK6","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RA2220-0HB23-0AK6/alternatives.json"},"ai":{"faq":[{"question":"What is the 3RA2220-0HB23-0AK6 rated for at 400 V?","answer":"It is rated 180 W at 400 V for motor starting in AC-3 duty.
