It's built in frame size S00 and snaps onto 60 mm busbar systems, which is the standard mounting for compact motor feeder assemblies in control panels. Rated for 180 W at 400 V and 500 V in AC-3 duty, and 250 W at 690 V, this starter handles small motor loads — pumps, fans, conveyors — in three-phase circuits up to 690 V. The magnetic short-circuit trip and integrated short-circuit protection (the supplied 3RV2011-0GA15 circuit-breaker) mean you don't need a separate fuse or MCCB upstream for the motor branch — it's self-protected within its ratings. ## What's in the box and how it fits This order code ships as a pre-assembled combination: the 3RT2015-1BB41 contactor, the 3RA1921-1DA00 link module, the 3RV2011-0GA15 circuit-breaker, and the 8US1251-5DS10 busbar adapter — everything needed for a single motor feeder, ready to snap onto the busbar. Dimensions are 200 mm high, 45 mm wide, and 155.1 mm deep — the width is a single 45 mm module, so it occupies one slot on the DIN rail or busbar. Mounting position is vertical, with required clearances: 20 mm upward, 10 mm downward, 9 mm to the side, and no space needed forward or backward — important to note when laying out the panel to avoid heat buildup from adjacent devices. The coil is 24 V DC with a holding power of 4 W — low enough to be driven by a standard 24 V DC power supply or PLC output, but check the inrush if multiple starters pull simultaneously. An auxiliary switch can be added (product extension auxiliary switch = Yes) for feedback to the PLC or status indication on the panel door.","metaTitle":"Siemens 3RA2115-0GD15-1BB4 SIRIUS Non-Fused Motor Starter","metaDescription":"Siemens SIRIUS 3RA2115-0GD15-1BB4 non-fused motor starter, direct starter, 180 W at 400 V, Class 10 trip, 24 V DC coil, snap-on 60 mm busbar.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Motor Starters"],"specifications":{"Depth":"155.1 mm","Width":"45 mm","title":"3RA2115-0GD15-1BB4","Height":"200 mm","Upwards":"20 mm","Forwards":"0 mm","Backwards":"0 mm","Downwards":"10 mm","Trip Class":"CLASS 10","At The Side":"9 mm","Rated Value":"24 V","description":"Fuseless motor starter Direct start 600VAC Size S00 0.45-0.63A 24V DC screw connection For snapping onto 60 mm busbar systems Type of coordination 2 IQ = 150 KA Also full fills type Of coordination 1 1NO+1NC (MSP) 1NO (contactor)","During Storage":"-50 ... +80 °C","lifecycle_stage":"current","During Operation":"-20 ... +60 °C","During Transport":"-55 ... +80 °C","Fastening Method":"for snapping onto 60 mm busbar systems","Mounting Position":"vertical","Product Brand Name":"SIRIUS","Type Of Assignment":"2","Degree Of Pollution":"3","Product Designation":"non-fused motor starter 3RA2","Size Of Load Feeder":"S00","at 400 V rated value":"180 W","at 500 V rated value":"180 W","at 690 V rated value":"250 W","Design Of The Product":"direct starter","Of The Supplied Contactor":"3RT2015-1BB41","Of The Supplied Link Module":"3RA1921-1DA00","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":"8US1251-5DS10","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":"3RV2011-0GA15","Product Extension Auxiliary Switch":"Yes","holding power of magnet coil at DC":"4 W","Surge Voltage Resistance Rated Value":"6 kV","Number Of Poles For Main Current Circuit":"3","Product Function Short Circuit Protection":"Yes","number of NC contacts for auxiliary contacts":"1","number of NO contacts for auxiliary contacts":"2","shock resistance according to IEC 60068-2-27":"6g / 11 ms","at 400 V according to IEC 60947-4-1 rated value":"153 000 A","at 500 V according to IEC 60947-4-1 rated value":"100 000 A","at 690 V according to IEC 60947-4-1 rated value":"100 000 A","operational current at AC-3 at 400 V rated value":"0.6 A","Type Of Electrical Connection For Main Current Circuit":"screw-type terminals","Mechanical Service Life (Operating Cycles) Of Contactor Typical":"30 000 000","Response Value Current Of Instantaneous Short-Circuit Trip Unit":"8.19 A","insulation voltage with degree of pollution 3 at AC rated value":"690 V","Type Of Connectable Conductor Cross-Sections For Main Contacts Stranded":"0.5 ... 4 mm², 2x (0.75 ... 2.5 mm²)","Adjustable Current Response Value Current Of The Current-Dependent Overload Release":"0.45 ... 0.63 A","Connectable Conductor Cross-Section For Main Contacts Finely Stranded With Core End Processing":"0.5 ... 2.5 mm²"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/74477da5d51df900073ccac8bf7ca8e1.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=519523&mlfb=3RA2115-0GD15-1BB4"},"ai":{"faq":[{"question":"What compliance documentation is available for 3RA2115-0GD15-1BB4?","answer":"Standard Siemens SIRIUS documentation includes RoHS, REACH, UL, and IEC compliance — available from the manufacturer on request."},{"question":"Will 3RA2115-0GD15-1BB4 drop into a panel specified around 3RV1011-0GA10 without rewiring?","answer":"Not directly — the 3RA2115-0GD15-1BB4 is a complete motor starter assembly (contactor + overload + breaker + busbar adapter), while the 3RV1011-0GA10 is a standalone circuit-breaker.
