The mounting position is vertical only. Control coil is 24 V DC, which is the standard industrial panel voltage. The supplied contactor is 3RT2015-2FB41, the link module is 3RA2911-2AA00, and the circuit-breaker is 3RV2011-1AA25 — all matched at the factory for coordination. ## Physical envelope and clearance requirements The starter occupies 45 mm width on the busbar, stands 260 mm tall, and projects 155 mm forward from the busbar face. That depth is the critical dimension for enclosure back-panel clearance — the busbar adapter 8US1251-5DT11 is supplied, so no separate adapter is needed. Clearance requirements: 50 mm above the unit, 20 mm below, 20 mm to the side, and 20 mm in front. Zero clearance behind — the busbar is the rear boundary. ## Environmental limits and terminal design Operating ambient range is -20 to +60 °C with temperature compensation active across that band. Storage and transport tolerance is -50 to +80 °C. Relative humidity during operation can run 10 to 95 % — no condensation limits stated, but that range covers most indoor industrial environments short of washdown zones. Both main current circuit and auxiliary/control circuit use spring-loaded terminals — no screw torque to verify, no vibration loosening. The product extension auxiliary switch is available (Yes), so a second contact block can be added without replacing the starter. The supplied components (contactor, link module, circuit-breaker, busbar adapter) are listed as factory-matched sub-assemblies — ordering the complete starter code ensures coordination between the overload relay and the magnetic short-circuit trip without separate selection.","metaTitle":"Siemens 3RA2115-1AH15-1FB4 SIRIUS DOL Starter, 550 W, 24 V","metaDescription":"Siemens 3RA2115-1AH15-1FB4 SIRIUS direct-on-line starter, 550 W at 400 V AC-3, 24 V DC coil, Class 10 thermal overload, S00 frame for 60 mm busbar.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Starters"],"specifications":{"Depth":"155 mm","Width":"45 mm","title":"3RA2115-1AH15-1FB4","Height":"260 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","description":"Load feeder fuseless, Direct-on-line starting 400 V AC, Size S00 1.10...1.60 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 (contactor) with diode (integrated)","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":"Direct (on-line) starter","Size Of Load Feeder":"S00","PROFINET IO protocol":"No","at 400 V rated value":"550 W","Design Of The Product":"for 60 mm busbars","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","Design Of The Overload Release":"thermal (bimetallic)","Of The Supplied Busbar Adapter":"8US1251-5DT11","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":"3RV2011-1AA25","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 %","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","number of NC contacts for auxiliary contacts":"1","number of NO contacts for auxiliary contacts":"1","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":"1.5 A","Mechanical Service Life (Switching Cycles) Of Contactor Typical":"30 000 000","insulation voltage with degree of pollution 3 at AC rated value":"690 V","Adjustable Current Response Value Current Of The Current-Dependent Overload Release":"1.1 ... 1.6 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/7948e90b50db1874bff7d9266637f458.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=552770&mlfb=3RA2115-1AH15-1FB4"},"ai":{"faq":[{"question":"How can I order 3RA2115-1AH15-1FB4 and check availability?","answer":"Submit an RFQ for volume pricing and lead time."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RA2115-1AH15-1FB4","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/3RA2115-1AH15-1FB4 when reusing this data.
