For resistive loads the AC-12 continuous current is 10 A, so it's not oversized for heater banks; the motor curve is where this part lives. The 45 mm width means it occupies one standard module slot in a panel — useful when you're packing multiple contactors in a row. Side-by-side mounting is allowed, so no forced spacing gaps. For AWG, that's 2x 16-12 solid or 1x 8 stranded on the main contacts. Type 1 coordination (contactor may need replacement after fault) allows a 100 A gL/gG fuse. That's a useful headroom range if you're coordinating with a motor starter or soft starter that has its own fuse spec. The coil draws 10 A at 24 V rated value, stepping down through the voltage range to 0.3 A at 220 V — standard for SIRIUS contactor coils. ## Environmental limits The front face carries IP20 protection — finger-safe when mounted in an enclosure, but the terminals themselves are IP00, so live parts are exposed if the contactor is not inside a panel.","metaTitle":"Siemens 3RT1026-1AT60 SIRIUS Power Contactor, S0, 11 kW AC-2","metaDescription":"Siemens 3RT1026-1AT60 SIRIUS power contactor, S0 frame, 3 NO main contacts, 11 kW at 400 V AC-2, 15.5 A AC-4, screw terminals, DIN rail mount, IP20 front, current production.","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":"11 kW","at 60 Hz rated value":"600 V","at 690 V rated value":"11 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":"11 kW","at AC-4 at 400 V rated value":"15.5 A","Operating current at AC-12 maximum":"10 A","With Type Of Assignment 2 Required":"fuse gL/gG: 35 A","at AWG conductors for main contacts":"2x (16 ... 12), 2x (14 ... 10), 1x 8","With Type Of Coordination 1 Required":"fuse gL/gG: 100 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=38562&mlfb=3RT1026-1AT60","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RT1026-1AT60/alternatives.json"},"ai":{"faq":[{"question":"What are the key motor ratings for this contactor?","answer":"AC-2 duty (wound-rotor motor) is 11 kW at 400 V.
