The unit ships with a 3RT2024-2BB40 contactor and a 3RA2921-2AA00 link module integrated. The 24 V DC coil is held at the nominal voltage; verify the control supply is stable within the rated range. The S0 footprint is 90 mm wide by 269 mm tall by 130 mm deep. These are the minimum air gaps for heat dissipation and arc containment; panel layout should respect them.","metaTitle":"Siemens 3RA2220-1JF24-0BB4 SIRIUS Reversing Load Feeder","metaDescription":"Siemens SIRIUS 3RA2220-1JF24-0BB4 reversing load feeder, S0 size, 10 A at 400 V AC-3, Class 10, 24 V DC coil, spring terminals.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Starters"],"specifications":{"Depth":"130 mm","Width":"90 mm","title":"3RA2220-1JF24-0BB4","Height":"269 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 installation on standard mounting rail with standard mounting rail adapter (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":"On adapter for screw and snap-on mounting on 35 mm DIN rail","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 230 V rated value":"1.5 hp","at 400 V rated value":"4 000 kW","at 480 V rated value":"10 A","at 600 V rated value":"10 A","Design Of The Product":"for standard rail or screw mounting","For Main Current Circuit":"spring-loaded terminals","Temperature Compensation":"-20 ... +60 °C","at 110/120 V rated value":"0.5 hp","at 200/208 V rated value":"3 hp","at 220/230 V rated value":"3 hp","at 460/480 V rated value":"7.5 hp","at 575/600 V rated value":"10 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","at AC-3 at 400 V rated value":"10 A","at AC-3e rated value maximum":"690 V","Substance Prohibitance (Date)":"03/01/2017","at AC-3e at 400 V rated value":"10 A","Design Of The Overload Release":"thermal (bimetallic)","Design Of The Switching Contact":"electromechanical","Operating Frequency Rated Value":"50 ... 60 Hz","of the supplied RH assembly kit":"3RA2923-1BB2","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 %","Without Load Current Share Typical":"5.9 W","holding power of magnet coil at DC":"5.9 W","Surge Voltage Resistance Rated Value":"6 kV","at AC in hot operating state per pole":"3.4 W","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 %","reference code according to IEC 81346-2:2019":"Q","shock resistance according to IEC 60068-2-27":"6g / 11 ms","Type Of Voltage Of The Control Supply Voltage":"DC","Of The Supplied Standard Mounting Rail Adapter":"3RA2922-1AA00","at 400 V according to IEC 60947-4-1 rated value":"150 000 A","Mechanical Service Life (Operating Cycles) Of Contactor Typical":"10 000 000","Response Value Current Of Instantaneous Short-Circuit Trip Unit":"130 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":"7 ... 10 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/303b63dad0b3cf82ca45b2e2cf4f8475.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=251132&mlfb=3RA2220-1JF24-0BB4"},"ai":{"faq":[{"question":"Does 3RA2220-1JF24-0BB4 include a contactor?","answer":"Yes.
