The 24 V DC coil keeps control transformer sizing predictable on a 24 VDC control bus. ## Mounting and panel fit — S00 frame on DIN rail Width is 45 mm, depth 97 mm, height 167 mm — the S00 footprint fits standard 35 mm DIN rail with screw and snap-on fastening. Vertical mounting position only; clearance above the unit is 50 mm, forward 20 mm, and 20 mm at the side for airflow and wiring access. Backwards clearance is zero — the unit sits flush against the mounting surface. Main circuit terminals are screw-type, sized for the S00 frame current. The supplied contactor is 3RT2015-1FB41 and the link module is 3RA1921-1DA00 — these are factory-integrated, so the starter arrives as a single assembly ready to wire. ## Ambient conditions and storage Operating temperature range is -20 to +60 °C with temperature compensation active across that band. Storage and transport limits are -50 to +80 °C — wide enough for unheated warehouses or container shipping. The 2.5 A AC-3 rating holds at 400 V up to 690 V maximum, so the starter can be used on 480 V or 600 V systems without voltage derating.","metaTitle":"Siemens 3RA2110-1CA15-1FB4 SIRIUS Motor Starter, 2.5 A AC-3","metaDescription":"Siemens 3RA2110-1CA15-1FB4 SIRIUS direct-on-line motor starter, size S00, 2.5 A at 400 V AC-3, Class 10 trip, 24 V coil, 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":"3RA2110-1CA15-1FB4","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 1.80...2.50 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 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 230 V rated value":"0.25 hp","at 400 V rated value":"750 kW","at 480 V rated value":"2.5 A","at 600 V rated value":"2.5 A","Design Of The Product":"for standard rail or screw mounting","For Main Current Circuit":"screw-type terminals","Temperature Compensation":"-20 ... +60 °C","at 110/120 V rated value":"0.1 hp","at 200/208 V rated value":"0.5 hp","at 220/230 V rated value":"0.75 hp","at 460/480 V rated value":"1.5 hp","at 575/600 V rated value":"2 hp","Of The Supplied Contactor":"3RT2015-1FB41","Of The Supplied Link Module":"3RA1921-1DA00","Size Of The Circuit-Breaker":"S00","at AC-3 rated value maximum":"690 V","at AC-3 at 400 V rated value":"2.5 A","at AC-3e rated value maximum":"690 V","at AC-3e at 400 V rated value":"2.5 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":"3RV2011-1CA10","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 %","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":"2.6 W","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 %","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":"33 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":"1.8 ... 2.5 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/f1a9465a978400fcf7e0d174e6f6c87f.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=296491&mlfb=3RA2110-1CA15-1FB4"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RA2110-1CA15-1FB4","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/3RA2110-1CA15-1FB4 when reusing this data.
