It ships as a pre-assembled combination: the contactor (3RT2015-2FB41), the link module (3RA2911-2AA00), and the circuit-breaker (3RV2011-0FA25) are supplied together, so you are not piecing three separate components for a standard motor feeder. The width is the critical panel-pitch dimension: at 45 mm it occupies one standard 45 mm slot on a DIN-rail assembly, matching the footprint of other S00 feeders. Clearance requirements: 50 mm upwards, 20 mm forwards, 20 mm at the side, 10 mm downwards, and 0 mm backwards — the zero backward clearance means it can sit flush against a back panel or enclosure wall. Main current circuit uses spring-loaded terminals (cage-clamp style), which speeds wiring compared to screw terminals and resists loosening under vibration — relevant for machine-mounted sub-panels.","metaTitle":"Siemens 3RA2115-0FE15-1FB4 SIRIUS Load Feeder S00, 120 kW","metaDescription":"Siemens 3RA2115-0FE15-1FB4 SIRIUS direct on-line starter, Size S00, 120 kW at 400 V, 24 V DC control, Class 10, spring terminals, DIN rail mount.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Starters"],"specifications":{"Depth":"97 mm","Width":"45 mm","Height":"198 mm","Upwards":"50 mm","Forwards":"20 mm","Backwards":"0 mm","Downwards":"10 mm","Trip Class":"CLASS 10","At The Side":"20 mm","Rated Value":"24 ... 24 V","During Storage":"-50 ... +80 °C","lifecycle_stage":"current","During Operation":"-20 ... +60 °C","During Transport":"-50 ... +80 °C","Fastening Method":"screw and snap-on mounting onto 35 mm DIN rail","Mounting Position":"vertical","PROFIsafe protocol":"No","Product Brand Name":"SIRIUS","Type Of Assignment":"2","Product Designation":"Direct (on-line) starter","Size Of Load Feeder":"S00","PROFINET IO protocol":"No","at 400 V rated value":"120 kW","at 480 V rated value":"0.5 A","at 600 V rated value":"0.5 A","Design Of The Product":"for standard rail or screw mounting","For Main Current Circuit":"spring-loaded terminals","Temperature Compensation":"-20 ... +60 °C","Of The Supplied Contactor":"3RT2015-2FB41","Of The Supplied Link Module":"3RA2911-2AA00","Size Of The Circuit-Breaker":"S00","at AC-3 rated value maximum":"690 V","at AC-3 at 400 V rated value":"0.5 A","at AC-3e rated value maximum":"690 V","at AC-3e at 400 V rated value":"0.5 A","Design Of The Overload Release":"thermal (bimetallic)","Design Of The Switching Contact":"electromechanical","Operating Frequency Rated Value":"50 ... 60 Hz","Design Of The Short-Circuit Trip":"magnetic","Of The Supplied Circuit-Breakers":"3RV2011-0FA25","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":"4 W","holding power of magnet coil at DC":"4 W","Surge Voltage Resistance Rated Value":"6 kV","at AC in hot operating state per pole":"2 W","Number Of Poles For Main Current Circuit":"3","Product Function Short Circuit Protection":"Yes","protocol is supported AS-Interface protocol":"No","number of NC contacts for auxiliary contacts":"1","number of NO contacts for auxiliary contacts":"1","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","at 400 V according to IEC 60947-4-1 rated value":"150 000 A","Mechanical Service Life (Operating Cycles) Of Contactor Typical":"30 000 000","Response Value Current Of Instantaneous Short-Circuit Trip Unit":"6.5 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":"0.35 ... 0.5 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=554152&mlfb=3RA2115-0FE15-1FB4","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RA2115-0FE15-1FB4/alternatives.json"},"ai":{"faq":[{"question":"Is 3RA2115-0FE15-1FB4 compatible with 24V DC control voltage?","answer":"Yes, the rated control voltage is 24 V DC (24... 24 V), making it directly compatible with standard 24 V DC PLC and safety relay outputs."},{"question":"Does 3RA2115-0FE15-1FB4 include a thermal overload relay?","answer":"Yes, the overload release is thermal bimetallic (Trip Class 10) and is integrated into the supplied circuit-breaker 3RV2011-0FA25 — it is not a separate add-on relay."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RA2115-0FE15-1FB4","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/3RA2115-0FE15-1FB4 when reusing this data.
