It ships as a pre-assembled unit with a 3RT2018-1AP01 contactor and a 3RA1921-1DA00 link module, so the coordination between the contactor and overload is factory-set. The screw-type main circuit terminals accept the motor and line wiring directly. ## Motor power coverage across common line voltages The starter covers a range of motor ratings: 1 hp at 110/120 V, 3 hp at 200/208 V, 5 hp at 220/230 V, 10 hp at 460/480 V, and 2 hp at 230 V. At 600 V the full-load current limit is 11 A; at 480 V it is 14 A. This voltage flexibility makes it suitable for export panels or multi-voltage plant floors where the same BOM line must serve 208 V and 480 V feeds. ## DIN rail mounting and clearance envelope Mounts vertically on 35 mm DIN rail via the snap-on foot, with screw fastening as an alternative. Clearance requirements: 50 mm above, 20 mm below, 20 mm to the side, and 20 mm forward; no clearance needed behind the rail. These numbers matter when laying out a dense panel — the 45 mm width leaves room for adjacent breakers or contactors in the same row.","metaTitle":"Siemens 3RA2110-4AA18-1AP0 SIRIUS Direct Starter, S00","metaDescription":"Siemens 3RA2110-4AA18-1AP0 SIRIUS direct online starter, size S00, 0.25 kW at 400 V 50/60 Hz, Class 10 trip, screw and snap-on 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":"3RA2110-4AA18-1AP0","Height":"167 mm","Upwards":"50 mm","Forwards":"20 mm","at 50 Hz":"0.25","at 60 Hz":"0.25","Backwards":"0 mm","Downwards":"10 mm","Trip Class":"CLASS 10","At The Side":"20 mm","Rated Value":"690 V","description":"Load feeder fuseless, Direct-on-line starting 400 V AC, Size S00 10...16 A 230 V AC screw terminal for installation on standard mounting rail Type of coordination 1, Iq = 150 kA 1 NO (contactor)","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":"1","Product Designation":"Direct (on-line) starter","Size Of Load Feeder":"S00","PROFINET IO protocol":"No","at 230 V rated value":"2 hp","at 400 V rated value":"7 500 kW","at 480 V rated value":"14 A","at 50 Hz rated value":"230 ... 230 V","at 60 Hz rated value":"230 ... 230 V","at 600 V rated value":"11 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":"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","Of The Supplied Contactor":"3RT2018-1AP01","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":"16 A","at AC-3e rated value maximum":"690 V","Substance Prohibitance (Date)":"10/01/2009","at AC-3e at 400 V rated value":"16 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":"3RV2011-4AA10","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":"5.7 W","Surge Voltage Resistance Rated Value":"6 kV","at AC in hot operating state per pole":"4.1 W","Number Of Poles For Main Current Circuit":"3","Product Function Short Circuit Protection":"Yes","apparent holding power of magnet coil at AC":"5.7 VA","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":"AC","at 400 V according to IEC 60947-4-1 rated value":"150 000 A","Inductive Power Factor With The Holding Power Of The Coil":"0.25","Mechanical Service Life (Operating 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":"10 ... 16 A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/45e02a91330fb880b25970aeeb147e40.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=90170&mlfb=3RA2110-4AA18-1AP0"},"ai":{"faq":[{"question":"What is the depth of 3RA2110-4AA18-1AP0?","answer":"The depth is 97 mm, with a width of 45 mm and height of 167 mm.
