The S0 frame means it fits the standard 45 mm width slot on a DIN rail, sharing the footprint with other SIRIUS components in the same panel layout. The 11 kW rating at 500 V and 690 V tells you this contactor handles standard three-phase induction motors up to that power at those voltages — typical for European 400/690 V networks. For AC-2 duty (slip-ring motors or wound-rotor applications), it also delivers 11 kW at 400 V. The coil pulls 10 A at 24 V on pickup, which is the inrush — steady-state holding current is lower. The 0.8 to 1.1 operating range at 50 Hz and 0.85 to 1.1 at 60 Hz means the coil holds in down to about 19.2 V at 50 Hz, which is useful if your control transformer sags under load. The 45 mm width and 85 mm height with 91 mm depth fit standard S0 enclosure cutouts. Front face is IP20, terminals are IP00 — so the panel door provides the touch protection. Main terminals accept screw-type connections: solid conductors 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), max 2x (0.75 to 4 mm²). For stranded or ferruled wire, use 2x (1 to 2.5 mm²), 2x (2.5 to 6 mm²), max 2x 10 mm². AWG equivalents are 2x (16 to 12), 2x (14 to 10), 1x 8.","metaTitle":"Siemens 3RT1026-1AC20-ZW96 SIRIUS Power Contactor, 11 kW at","metaDescription":"Siemens SIRIUS 3RT1026-1AC20-ZW96 power contactor, S0 frame, 11 kW at 500 V, 24 V 50/60 Hz coil, screw terminals, current lifecycle status, DIN rail mount.","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 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":"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 50 Hz rated value":"24 V","at 500 V rated value":"11 kW","at 60 Hz rated value":"24 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":"8.4 V·A","Apparent pick-up power of magnet coil at AC":"64 V·A","Type of voltage of the control supply voltage":"AC","Inductive power factor with closing power of the coil":"0.72","Inductive power factor with the holding power of the coil":"0.24","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=265247&mlfb=3RT1026-1AC20-ZW96","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RT1026-1AC20-ZW96/alternatives.json"},"ai":{"faq":[{"question":"What are the key motor ratings for this contactor?","answer":"It is rated 11 kW at both 500 V and 690 V for AC-3 duty.
