It ships as a factory-assembled unit containing a 3RT2024-2BB40 contactor, a 3RA2921-2AA00 link module, and an 8US1251-5NT11 busbar adapter — three components that would otherwise need separate ordering and wiring. ## Mounting and clearance envelope The reversing starter measures 260 mm high by 90 mm wide by 165 mm deep, and mounts vertically on the busbar system — the vertical orientation is specified for proper thermal convection through the bimetallic overload. Minimum clearances around the unit: 50 mm above, 32 mm in front, 10 mm below, 10 mm at the sides, and 0 mm behind (the back sits flush against the busbar adapter). These gaps must be maintained for cooling air flow and arc-flash containment. ## Termination and environmental limits Main current circuit connections use spring-loaded terminals — no screw torque verification needed, and the connection stays tight under vibration. The spring clamp accepts solid or ferruled stranded wire without periodic retightening. Operating temperature range is -20 to +60 °C, with storage and transport tolerance from -50 to +80 °C. The 24 V control voltage is listed as 24... 24 V, indicating a fixed 24 V DC/AC coil — confirm the control supply polarity if DC. ## Lifecycle and compliance No stock-holding claim — quoted per order.","metaTitle":"Siemens 3RA2220-1JH24-0BB4 Reversing Starter, S0","metaDescription":"Siemens SIRIUS 3RA2220-1JH24-0BB4 reversing starter, size S0, 4 kW at 400 V AC-3, Class 10 thermal overload, spring terminals, for 60 mm busbars.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Starters"],"specifications":{"Depth":"165 mm","Width":"90 mm","title":"3RA2220-1JH24-0BB4","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":"24 ... 24 V","description":"Load feeder fuseless, Reversing duty 400 V AC, Size S0 7.00...10.0 A 24 V DC 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","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":"3RT2024-2BB40","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 %","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","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":"DC","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/a27f6dfb0b093510ebce126901a8924f.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=285916&mlfb=3RA2220-1JH24-0BB4"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to 3RA2220-1JH24-0BB4 in this Motor Starters family?","answer":"No official successor or direct cross-reference is recorded for this reversing starter.
