It's a screw-terminal unit with an IP20 front face, meaning the terminals themselves are touch-safe once wired, but the contactor is meant for a clean, enclosed panel, not a washdown zone. Side-by-side mounting is allowed with no derating gap, so you can pack several in a row without losing thermal headroom. Rated for 11 kW at 400 V AC-2, this contactor handles motor loads that pull starting current but don't need the full AC-3 or AC-4 interrupting capability. In a cement plant, that fits preheater fan drives or clinker conveyor motors that start under partial load. The AC-4 rating of 15.5 A at 400 V tells you the contactor can also manage plugging or inching duty — reversing or jogging a motor under load — though at a lower power than its AC-2 rating. Pollution degree 3 rating confirms design for conductive dust environments. That's a clean, standard spec that any panel builder can implement without special fusing. ## Wiring and auxiliary contacts Main circuit terminals accept 2x (1 to 2.5 mm²) stranded, 2x (2.5 to 6 mm²), or up to 2x 10 mm² — solid or ferruled. The auxiliary contact block (included in the -ZW96 variant) handles 24 V DC at 10 A, 60 V DC at 2 A, and 230 V AC at 6 A, which covers most PLC output signals and pilot devices on a standard control circuit. If you're replacing a 3RT1023-1AL20 (smaller S0 frame, lower rating), check your motor load: the 3RT1026 carries 11 kW AC-2 versus the 1023's lower rating, so it's an upgrade in capacity but shares the same 45 mm footprint and terminal layout.","metaTitle":"Siemens 3RT1026-1AL20-ZW96 SIRIUS Power Contactor, Size S0,","metaDescription":"Siemens SIRIUS 3RT1026-1AL20-ZW96 power contactor, Size S0, 11 kW at 400V AC-2, 45mm wide, IP20 front, screw terminals, current lifecycle status, available 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 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":"230 V","at 500 V rated value":"11 kW","at 60 Hz rated value":"230 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=327864&mlfb=3RT1026-1AL20-ZW96","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RT1026-1AL20-ZW96/alternatives.json"},"ai":{"faq":[{"question":"What compliance documentation does this brand provide for 3RT1026-1AL20-ZW96 (RoHS, REACH, UL, IEC)?","answer":"As a Siemens SIRIUS product, this contactor carries CE marking for the European market and is designed to IEC/EN 60947-4-1 standards.
