The integrated assembly ships with a 3RT2015-2FB41 contactor, a 3RV2011-0DA25 circuit-breaker, and a 3RA2911-2AA00 link module — the three pieces are pre-coordinated for Type 2 coordination, so you get a single order code that covers the motor branch circuit protection, switching, and overload. The thermal bimetallic overload release is set to Class 10 trip curve, meaning it clears a stalled-rotor condition fast enough to protect the motor winding before the temperature rise exceeds the insulation class. ## 45 mm wide — DIN-rail footprint and clearances The mounting method is screw and snap-on — the DIN rail latch engages first, then the screw secures it against vibration. Vertical mounting position is specified; the upwards clearance of 50 mm and forwards clearance of 20 mm are the minimums needed for wiring access and heat dissipation from the bimetallic overload. The main current circuit uses spring-loaded terminals — strip the wire, push it in, no screwdriver needed for the power connections. The control circuit termination is not specified in this data, but the 24 V DC coil wiring typically lands on the link module's screw terminals. Depth is 97 mm from the DIN rail backplane to the front of the housing, so a 100 mm deep enclosure leaves just enough clearance for the wiring ducts.","metaTitle":"Siemens 3RA2115-0DE15-1FB4 SIRIUS Motor Starter","metaDescription":"Siemens SIRIUS 3RA2115-0DE15-1FB4 direct online motor starter, 90 kW at 400 V AC-3, Class 10, 24 V DC coil, spring terminals, DIN rail.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Motor Starters"],"specifications":{"Depth":"97 mm","Width":"45 mm","title":"3RA2115-0DE15-1FB4","Height":"198 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 0.22...0.32 A 24 V DC Spring-type terminal for installation on standard mounting rail (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":"screw and snap-on mounting onto 35 mm DIN 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":"90 kW","at 480 V rated value":"0.32 A","at 600 V rated value":"0.32 A","Design Of The Product":"for standard rail or screw mounting","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","at AC-3 at 400 V rated value":"0.32 A","at AC-3e rated value maximum":"690 V","at AC-3e at 400 V rated value":"0.32 A","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":"3RV2011-0DA25","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 %","Without Load Current Share Typical":"4 W","holding power of magnet coil at DC":"4 W","Surge Voltage Resistance Rated Value":"6 kV","at AC in hot operating state per pole":"2 W","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","reference code according to IEC 81346-2:2019":"Q","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","Mechanical Service Life (Operating Cycles) Of Contactor Typical":"30 000 000","Response Value Current Of Instantaneous Short-Circuit Trip Unit":"4.2 A","insulation voltage with degree of pollution 3 at AC rated value":"690 V","Adjustable Current Response Value Current Of The Current-Dependent Overload Release":"0.22 ... 0.32 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/df8b916af534aaab6fa2c0a099400741.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=553632&mlfb=3RA2115-0DE15-1FB4"},"ai":{"faq":[{"question":"What is the 3RA2115-0DE15-1FB4's motor power rating at 400 V?","answer":"The trip class is Class 10, so it protects the motor against stalled rotor conditions within the thermal limit of the winding insulation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RA2115-0DE15-1FB4","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RA2115-0DE15-1FB4 when reusing this data.
