It ships as a pre-assembled unit: the 3RT2015-2FB41 contactor, a 3RV2011-0CA25 circuit breaker with magnetic short-circuit trip, and a thermal bimetallic overload relay set to CLASS 10 trip curve. ## Clearance and mounting — no surprises Dimensions are 155 mm deep, 45 mm wide, 260 mm tall. Mounting is vertical only. Minimum clearances: 50 mm above, 20 mm below, 20 mm at the sides, 20 mm forward, 0 mm backward — the back can sit flush against the panel. Operating temperature range is -20 to +60 °C with 10–95 % relative humidity; storage and transport tolerate -50 to +80 °C. ## Termination and expansion Both the main current circuit and the auxiliary/control circuit use spring-loaded terminals — no screwdriver torque check needed, just push in the stripped wire. The starter supports an auxiliary switch extension (product extension auxiliary switch: Yes), so you can add feedback contacts without a separate enclosure. The supplied busbar adapter (8US1251-5DT11) and link module (3RA2911-2AA00) are included — the starter is ready to clip onto the 60 mm system out of the box. ## Lifecycle and sourcing No direct second-source cross-reference is listed; the 6ES7517-3FP00-0AB0 is a Siemens PLC CPU, not a motor starter, and does not share the S00 busbar footprint or function.","metaTitle":"Siemens 3RA2115-0CH15-1FB4 SIRIUS Direct Starter, S00, 24 V","metaDescription":"Siemens 3RA2115-0CH15-1FB4 SIRIUS direct online starter, S00 frame, 24 VDC control, CLASS 10 thermal overload, 60 mm busbar mount.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Starters"],"specifications":{"Depth":"155 mm","Width":"45 mm","title":"3RA2115-0CH15-1FB4","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 0.18...0.25 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":"60 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":"3RV2011-0CA25","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":"0.2 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":"0.18 ... 0.25 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/a2df0772dd51ef098fa1cff53a49b0e3.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=553663&mlfb=3RA2115-0CH15-1FB4"},"ai":{"faq":[{"question":"What is the trip class and overload protection type?","answer":"It uses a thermal bimetallic overload release set to CLASS 10, with a magnetic short-circuit trip in the supplied circuit breaker."},{"question":"Will 3RA2115-0CH15-1FB4 drop into a panel specified around 6ES7517-3FP00-0AB0?","answer":"No — the 6ES7517-3FP00-0AB0 is a Siemens S7-1500 CPU, not a motor starter.
