The 4-pole configuration means it can switch a three-phase motor plus a neutral or a second load leg, or be used for resistive loads where you need four switched lines. The 24 VDC coil is what pulls the contacts in; the holding voltage range is 0.8 to 1.1 times rated at 50 Hz and 0.85 to 1.1 at 60 Hz, so it stays sealed across a typical control supply sag. The auxiliary contact ratings — 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V — cover the PLC output or relay that drives it, and the contactor itself carries no built-in auxiliary contacts (shows zero NC on main contacts), so plan for an external auxiliary block if you need feedback. The footprint is 45 mm wide, 57.5 mm tall, and 72 mm deep — that 45 mm width is the key dimension for rail spacing and enclosure fill. The screw-type terminals on the main current circuit accept solid and stranded conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and max 2x (0.75 to 4 mm²). For AWG, that's 2x (20 to 16), 2x (18 to 14), and 1x 12. The IP20 rating on the front and terminals means finger-safe for the panel builder, but not protected against dust ingress — this is a standard control-panel part, not for open-air or washdown zones. ## Coordination and protection requirements Electrical life depends on the switching current and duty cycle; for motor switching at 5.5 kW, expect significantly fewer operations, but the mechanical floor tells you the actuator won't be the first thing to fatigue.","metaTitle":"Siemens 3RT1317-1AN20 SIRIUS Power Contactor, 5.5 kW at 400","metaDescription":"Siemens SIRIUS 3RT1317-1AN20 4-pole power contactor, size S00, 5.5 kW at 400 V AC-2/AC-3, 24 VDC coil, screw terminals, IP20, current production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Contactors"],"specifications":{"Depth":"72 mm","Solid":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²), max. 2x (0.75 ... 4 mm²)","Width":"45 mm","Height":"57.5 mm","at 50 Hz":"0.8 ... 1.1","at 60 Hz":"0.85 ... 1.1","At The Side":"6 mm","On The Front":"IP20","1 Rated Value":"50 Hz","2 Rated Value":"60 Hz","Mounting Type":"screw and snap-on mounting onto 35 mm standard mounting rail according to DIN EN 50022","Of The Terminal":"IP20","lifecycle_stage":"current","During Operation":"-25 ... +60 °C","Size Of Contactor":"S00","Product Brand Name":"SIRIUS","Degree Of Pollution":"3","Product Designation":"power contactor","at 24 V rated value":"10 A","at 60 V rated value":"2 A","Of Contactor Typical":"30 000 000","at 110 V rated value":"1 A","at 220 V rated value":"0.3 A","at 400 V rated value":"5.5 kW","at 50 Hz rated value":"220 V","at 60 Hz rated value":"220 V","Instantaneous Contact":"0","Side-By-Side Mounting":"Yes","For Main Current Circuit":"screw-type terminals","Single Or Multi-Stranded":"2x (0,5 ... 1,5 mm²), 2x (0,75 ... 2,5 mm²), max. 2x (0,75 ... 4 mm²)","at AC-2 at 400 V rated value":"5.5 kW","With Type Of Assignment 2 Required":"fuse gL/gG: 20 A","operating current at AC-12 maximum":"10 A","at AWG conductors for main contacts":"2x (20 ... 16), 2x (18 ... 14), 1x 12","With Type Of Coordination 1 Required":"fuse gL/gG: 35 A","reference code acc. to DIN EN 81346-2":"Q","number of NC contacts for main contacts":"0","number of NO contacts for main contacts":"4","Finely Stranded With Core End Processing":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²)","Number Of Poles For Main Current Circuit":"4","Contact Reliability Of Auxiliary Contacts":"1 faulty switching per 100 million (17 V, 1 mA)","For Auxiliary And Control Current Circuit":"screw-type terminals","at ambient temperature 40 °C rated value":"22 A","apparent holding power of magnet coil at AC":"4.4 V·A","apparent pick-up power of magnet coil at AC":"27 V·A","Type Of Voltage Of The Control Supply Voltage":"AC","operating current at AC-15 at 230 V rated value":"6 A","operating current at AC-15 at 400 V rated value":"3 A","Inductive Power Factor With Closing Power Of The Coil":"0.8","Installation Altitude At Height Above Sea Level Maximum":"2 000 m","Inductive Power Factor With The Holding Power Of The Coil":"0.27","Of The Contactor With Added Auxiliary Switch Block Typical":"10 000 000","For Short-Circuit Protection Of The Auxiliary Switch Required":"fuse gL/gG: 10 A","Of The Contactor With Added Electronics-Compatible Auxiliary Switch Block Typical":"5 000 000","type of connectable conductor cross-sections at AWG conductors for auxiliary contacts":"2x (20 ... 16), 2x (18 ... 14), 1x 12"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=203399&mlfb=3RT1317-1AN20","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RT1317-1AN20/alternatives.json"},"ai":{"faq":[{"question":"What are the key motor ratings for this contactor?","answer":"The contactor is rated for 5.5 kW at 400 V under both AC-2 and AC-3 duty.
