The 550 W rating at 400 V and 1.6 A at 480 V tell you the motor load it can handle continuously in AC-3 duty; the 0.75 hp figures at 460/480 V and 575/600 V confirm it fits fractional-horsepower motors common in conveyor, pump, and fan applications across North American and 400 V line voltages. The thermal bimetallic design tracks motor heating; the magnetic short-circuit trip handles fault clearing. Both main and auxiliary/control terminals are screw-type — no special tooling needed, just a standard slotted or Pozidriv driver. ## DIN rail mounting and panel clearance The dimensions — 97 mm depth, 45 mm width, 167 mm height — fit the S00 footprint that shares the same rail pitch as other SIRIUS S00 components. Clearance requirements: 50 mm upwards, 20 mm forwards, 20 mm at the side, 10 mm downwards, and 0 mm backwards. That 0 mm backwards clearance means the back of the unit can sit flush against the panel backplate — useful when you're packing components on a tight gland plate. ## Supplied components — what's in the box The starter ships with three pre-selected components: the contactor 3RT2016-1BB42, the circuit-breaker 3RV2011-1AA15, and the link module 3RA1921-1DA00 that ties them together. This is a coordinated assembly — you don't pick the overload or breaker separately. If you're swapping a failed unit, order the whole 3RA2115-1AA16-2BB4; the individual sub-components are available as spares but the coordination curve is factory-set.","metaTitle":"Siemens 3RA2115-1AA16-2BB4 SIRIUS Direct Starter, S00","metaDescription":"Siemens 3RA2115-1AA16-2BB4 SIRIUS direct (on-line) starter, size S00, 550 W at 400 V, Class 10 thermal overload, screw terminals, DIN rail mount.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Starters"],"specifications":{"Depth":"97 mm","Width":"45 mm","title":"3RA2115-1AA16-2BB4","Height":"167 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 screw terminal for installation on standard mounting rail (also fulfills type of coordination 1) Type of coordination 2, Iq = 150 kA 1 NC (contactor) 1 NO+1 NC (circuit breaker, transverse)","During Storage":"-50 ... +80 °C","lifecycle_stage":"current","During Operation":"-20 ... +60 °C","During Transport":"-50 ... +80 °C","Fastening Method":"screw and snap-on mounting onto 35 mm standard mounting rail","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","at 480 V rated value":"1.6 A","Design Of The Product":"for standard rail or screw mounting","For Main Current Circuit":"screw-type terminals","Temperature Compensation":"-20 ... +60 °C","at 460/480 V rated value":"0.75 hp","at 575/600 V rated value":"0.75 hp","Of The Supplied Contactor":"3RT2016-1BB42","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)","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":"3RV2011-1AA15","degree of protection NEMA rating":"other","For Auxiliary And Control Circuit":"screw-type terminals","Product Extension Auxiliary Switch":"Yes","Relative Humidity During Operation":"10 ... 95 %","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","protocol is supported AS-Interface protocol":"No","with high demand rate according to SN 31920":"73 %","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/803ce779cbc0e91565bca512c1d2e69d.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=508179&mlfb=3RA2115-1AA16-2BB4"},"ai":{"faq":[{"question":"What motor power does 3RA2115-1AA16-2BB4 handle at 400 V?","answer":"At 400 V AC-3 duty, the starter is rated for 550 W.
