For reversing or plugging duty (AC-4), the rated operating current is 12.5 A at 400 V, a lower figure because the contacts must interrupt full-load current at each reversal. Type 1 coordination allows a 63 A fuse, which will destroy the contactor but clear the fault. ## Integration — DIN rail, wiring, and clearances The screw terminals accept solid or stranded conductors: main contacts take 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or up to 2x (0.75 to 4 mm²); the auxiliary/coil terminals are not separately listed but the main circuit terminal range covers the typical control wiring sizes. AWG equivalents are 2x (16 to 12), 2x (14 to 10), and 1x 8.","metaTitle":"Siemens 3RT1024-1AU60 SIRIUS Power Contactor, 3 NO, S0 Frame","metaDescription":"Siemens SIRIUS 3RT1024-1AU60 power contactor, S0 frame, 3 NO main contacts, 12.5 A at AC-4 400 V, screw terminals, 45 mm wide, current lifecycle stage, sourced to order against RFQ","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Contactors"],"specifications":{"Depth":"91 mm","Solid":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²), max. 2x (0.75 ... 4 mm²)","Width":"45 mm","Height":"85 mm","Maximum":"2 000 m","at 60 Hz":"0.8 ... 1.1","At The Side":"6 mm","On The Front":"IP20","1 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":"IP00","lifecycle_stage":"current","During Operation":"-25 ... +60 °C","Size of contactor":"S0","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":"10 000 000","at 110 V rated value":"1 A","at 220 V rated value":"0.3 A","at 230 V rated value":"6 A","at 400 V rated value":"3 A","at 500 V rated value":"7.5 kW","at 60 Hz rated value":"277 V","at 690 V rated value":"7.5 kW","Instantaneous Contact":"0","Side-by-side mounting":"Yes","For Main Current Circuit":"screw-type terminals","Single Or Multi-Stranded":"2x (1 ... 2,5 mm²), 2x (2,5 ... 6 mm²), max. 2x 10 mm²","at AC-2 at 400 V rated value":"5.5 kW","at AC-4 at 400 V rated value":"12.5 A","Operating current at AC-12 maximum":"10 A","With Type Of Assignment 2 Required":"fuse gL/gG: 25 A","at AWG conductors for main contacts":"2x (16 ... 12), 2x (14 ... 10), 1x 8","With Type Of Coordination 1 Required":"fuse gL/gG: 63 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":"3","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":"3","at AWG conductors for auxiliary contacts":"2x (20 ... 16), 2x (18 ... 14), 1x 12","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":"40 A","Apparent holding power of magnet coil at AC":"7.5 V·A","Apparent pick-up power of magnet coil at AC":"69 V·A","Type of voltage of the control supply voltage":"AC","Inductive power factor with closing power of the coil":"0.76","Inductive power factor with the holding power of the coil":"0.28","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"}},"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=410444&mlfb=3RT1024-1AU60","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RT1024-1AU60/alternatives.json"},"ai":{"faq":[{"question":"What is 3RT1024-1AU60's depth?","answer":"The depth is 91 mm, with a width of 45 mm and height of 85 mm."},{"question":"What conductor sizes does 3RT1024-1AU60 accept?","answer":"The screw terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and up to 2x (0.75 to 4 mm²) solid or stranded conductors.
