This protects the motor during a stalled-rotor or locked-rotor event without nuisance tripping on normal starting inrush. It ships as a pre-assembled kit: the supplied contactor is 3RT2015-2FB41, the circuit-breaker is 3RV2011-1BA25, the link module is 3RA2911-2AA00, and the busbar adapter is 8US1251-5DT11. Everything needed for a coordinated motor feeder in one order code. ## Snaps onto 60 mm busbar — spring-loaded terminals throughout This starter is designed for snapping onto 60 mm busbar systems — the standard panel-building approach for SIRIUS S00 feeders. Mounting position is vertical only, with 50 mm clearance upward, 20 mm forward, 20 mm at the side, and 10 mm downward for airflow and wiring access. Both the main current circuit and the auxiliary/control circuit use spring-loaded terminals — no screw tightening, no torque check. This speeds panel wiring and holds reliably under vibration. The envelope is 45 mm wide × 260 mm high × 155 mm deep — a compact S00 footprint that fits standard 400 mm deep enclosures with room for the busbar behind.","metaTitle":"Siemens 3RA2115-1BH15-1FB4 SIRIUS Direct Starter","metaDescription":"Siemens 3RA2115-1BH15-1FB4 SIRIUS direct-on-line starter, 750W at 400V AC-3, Class 10 thermal overload, S00 frame, spring-loaded terminals, snaps onto 60mm","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Starters"],"specifications":{"Depth":"155 mm","Width":"45 mm","title":"3RA2115-1BH15-1FB4","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 1.40...2.00 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":"750 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":"3RV2011-1BA25","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":"1.9 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":"1.4 ... 2 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/35acd81485c7c30bcf171c9c93451e51.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=552191&mlfb=3RA2115-1BH15-1FB4"},"ai":{"faq":[{"question":"What is the 3RA2115-1BH15-1FB4 rated for at 400 V?","answer":"The trip class is Class 10, and the operating frequency is 50/60 Hz."},{"question":"What components are included in the 3RA2115-1BH15-1FB4 kit?","answer":"The kit includes the contactor 3RT2015-2FB41, the circuit-breaker 3RV2011-1BA25, the link module 3RA2911-2AA00, and the busbar adapter 8US1251-5DT11.
