The 750 W rating at 400 V AC-3 defines the maximum three-phase motor load this starter can switch under standard starting conditions — a 0.75 kW motor at 400 V line-to-line. Spring-loaded terminals on both the main and auxiliary/control circuits eliminate the need for screwdriver torque checks — push the stripped wire in and the cage clamps it. The supplied contactor is a 3RT2015-2FB41, the link module is 3RA2911-2AA00, the circuit breaker is a 3RV2011-1CA25, and the busbar adapter is 8US1251-5DT11 — all matched for the S00 frame. Mounting position is vertical only, with required clearances: 50 mm upwards, 20 mm forwards, 10 mm downwards, 20 mm at the side, and 0 mm backwards (–). The 45 mm width and 260 mm height fit standard S00 panel layouts; the 155 mm depth accounts for the busbar adapter and wiring space.","metaTitle":"Siemens 3RA2115-1CH15-1FB4 Direct Starter, S00","metaDescription":"Siemens SIRIUS 3RA2115-1CH15-1FB4 direct-on-line starter, size S00, 750 W at 400 V AC-3, Class 10, spring terminals, for 60 mm busbars.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Starters"],"specifications":{"Depth":"155 mm","Width":"45 mm","title":"3RA2115-1CH15-1FB4","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 1.80...2.50 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":"3RV2011-1CA25","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":"1.8 ... 2.5 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/5895df0dfa4e713c9b698ed8214a540a.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=553128&mlfb=3RA2115-1CH15-1FB4"},"ai":{"faq":[{"question":"What is the 3RA2115-1CH15-1FB4 rated for?","answer":"It is a direct-on-line starter rated 750 W at 400 V AC-3, with a Class 10 trip characteristic.
