Rated motor power hits 7500 W at 400 V and 10 hp at both 460/480 V and 575/600 V — the 14 A at 480 V and 11 A at 600 V figures tell you the current ceiling in North American 60 Hz applications. ## Size S00 footprint on 60 mm busbar Size S00 load feeder — the smallest SIRIUS frame — keeps the panel width to 45 mm and depth to 155.1 mm, with a total height of 200 mm. Mounts by snapping directly onto 60 mm busbar systems — no DIN rail adapter needed, which saves a row of rail and speeds up assembly in busbar-fed distribution panels. Mounting position is vertical only; clearance above the unit is 20 mm and below is 10 mm, with 9 mm to the side — tight enough for dense busbar layouts but plan the 20 mm upward for heat rise from the bimetallic element. ## Integrated contactor and link module included Ships with the 3RT2018-1AP61 contactor and 3RA1921-1DA00 link module already assembled — one order code, one stock-keeping unit, no separate contactor and overload to match. The supplied contactor handles the AC-3 switching duty up to 690 V; the link module connects the overload output to the contactor coil circuit so the starter drops out on overload without auxiliary wiring. For the MRO storeroom, this is a fast mover — one line item replaces three separate part numbers (contactor, overload relay, link), simplifying the min/max stock level. Volume pricing and lead time confirmed at RFQ. The 3RA2110-4AD18-1AP6 is a standard catalog item under the SIRIUS brand — no special lead-time risk for project builds or MRO spares.","metaTitle":"Siemens 3RA2110-4AD18-1AP6 Motor Starter, SIRIUS","metaDescription":"Siemens 3RA2110-4AD18-1AP6 SIRIUS non-fused motor starter, 14 A at 480 V, Class 10 thermal overload, 690 V rated, snaps onto 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":"3RA2110-4AD18-1AP6","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":"690 V","description":"Fuseless motor starter Direct start 600VAC Size S00 11-16Amp 220/240VAC 50/60HZ screw connection For snapping onto 60 mm busbar systems Type of coordination 1 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":"1","Degree Of Pollution":"3","Product Designation":"non-fused motor starter 3RA2","Size Of Load Feeder":"S00","at 230 V rated value":"2 hp","at 400 V rated value":"7 500 W","at 480 V rated value":"14 A","at 50 Hz rated value":"187 ... 242 V","at 500 V rated value":"7 500 W","at 60 Hz rated value":"192 ... 264 V","at 600 V rated value":"11 A","Design Of The Product":"direct starter","at 110/120 V rated value":"1 hp","at 200/208 V rated value":"3 hp","at 220/230 V rated value":"5 hp","at 460/480 V rated value":"10 hp","at 575/600 V rated value":"10 hp","Of The Supplied Contactor":"3RT2018-1AP61","For Main Contacts Stranded":"0.5 ... 4 mm², 2x (0.75 ... 2.5 mm²)","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","at AWG cables for main contacts":"2x (20 ... 16), only for contactor 2x (18 ... 14), 2x 12","Design Of The Short-Circuit Trip":"magnetic","Of The Supplied Circuit-Breakers":"3RV2011-4AA10","Product Extension Auxiliary Switch":"Yes","Surge Voltage Resistance Rated Value":"6 kV","Number Of Poles For Main Current Circuit":"3","Product Function Short Circuit Protection":"Yes","apparent holding power of magnet coil at AC":"6.5 VA","number of NC contacts for auxiliary contacts":"0","number of NO contacts for auxiliary contacts":"1","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","operational current at AC-3 at 400 V rated value":"15.5 A","Type Of Electrical Connection For Main Current Circuit":"screw-type terminals","Inductive Power Factor With The Holding Power Of The Coil":"0.25","Mechanical Service Life (Switching Cycles) Of Contactor Typical":"30 000 000","Response Value Current Of Instantaneous Short-Circuit Trip Unit":"208 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":"11 ... 16 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/e6de111daaca0d2d0de0b6478c4d8442.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=258299&mlfb=3RA2110-4AD18-1AP6"},"ai":{"faq":[{"question":"What are the key ratings for 3RA2110-4AD18-1AP6?","answer":"Rated insulation voltage 690 V, AC-3 rated voltage maximum 690 V.
