AWG equivalents are 2× (16 to 12) or 2× (14 to 8). The magnetic short-circuit trip handles fault clearing without relying on upstream fuses for the starter's own protection. Mounting position is vertical only — the bimetallic strip's response curve assumes gravity-assisted convection across the heater element. ## Supplied as a coordinated assembly This order code ships as a pre-coordinated set: the 3RT2023-1BB40 contactor, the 3RA2921-1BA00 link module, the 3RV2011-0GA10 circuit breaker (size S00), the 3RA2922-1AA00 busbar adapter, and the 3RA2923-1BB1 RH assembly kit — all factory-matched for the reversing configuration. The auxiliary switch extension is available (product extension auxiliary switch: Yes), and the 24 V DC coil draws 5.9 W holding power — relevant for control transformer sizing when multiple starters share a common supply. ## Active production — sourcing posture The pre-coordinated assembly means no separate procurement of contactor, overload, and breaker — one order code covers the reversing pair.","metaTitle":"Siemens 3RA2220-0GB23-0BB4 SIRIUS Reversing Motor Starter","metaDescription":"Siemens 3RA2220-0GB23-0BB4 SIRIUS non-fused reversing motor starter, size S0, Class 10 thermal overload, 690 V AC-3 max, snap-on 35 mm DIN rail.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Motor Starters"],"specifications":{"Depth":"130 mm","Width":"90 mm","title":"3RA2220-0GB23-0BB4","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":"24 V","description":"Combination Starter Reversing FLA Ramge 0.45-0.63A 3 Pole 24VDC Coil S2 Open Type 1NO <(>&<)> 1NC Aux","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 500 V rated value":"180 W","at 690 V rated value":"250 W","Design Of The Product":"reversing starter","Of The Supplied Contactor":"3RT2023-1BB40","For Main Contacts Stranded":"1 ... 10 mm², 2x (2.5 ... 6 mm²)","Of The Supplied Link Module":"3RA2921-1BA00","Size Of The Circuit-Breaker":"S00","at AC-3 rated value maximum":"690 V","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":"3RV2011-0GA10","Product Extension Auxiliary Switch":"Yes","holding power of magnet coil at DC":"5.9 W","Surge Voltage Resistance Rated Value":"6 kV","Number Of Poles For Main Current Circuit":"3","Product Function Short Circuit Protection":"Yes","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","Mechanical Service Life (Switching Cycles) Of Contactor Typical":"10 000 000","Response Value Current Of Instantaneous Short-Circuit Trip Unit":"8.19 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":"0.45 ... 0.63 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":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/084a5a277f8c5b02e14de3a0daa3598c.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=59207&mlfb=3RA2220-0GB23-0BB4"},"ai":{"faq":[{"question":"Where can I buy 3RA2220-0GB23-0BB4 and get a price?","answer":"Available to order through independent industrial distribution.
