The coil tolerance spans 0.8 to 1.1 times rated voltage at 50 Hz and 0.85 to 1.1 at 60 Hz, so it holds in through brownout conditions that would drop out a tighter-coil contactor. The 45 mm width (three module spaces) and 88 mm height fit the S0 footprint common across the SIRIUS contactor family, so panel layout and busbar planning are straightforward if you're replacing or expanding an existing SIRIUS installation. For resistive loads (AC-1), the maximum operating current is 10 A. The auxiliary contact block is a 2-pole instantaneous contact (NO/NC configurable by wiring). The integrated varistor surge suppressor on the coil means you don't need an external RC snubber for standard 24 VAC control circuits — it handles the inductive kick internally, saving a component and a wiring step. Termination is screw-type for the main circuit, accepting 2x (1 to 2.5 mm²) or 2x (2.5 to 6 mm²) solid/stranded, with a maximum of 2x 10 mm². The control circuit terminals accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²), up to 4 mm² max. That covers standard panel wire sizes without adapters. IP20 on the front, IP00 at the terminals: the body is touch-safe, but the wiring terminations need enclosure protection.","metaTitle":"Siemens SIRIUS 3RT1026-1CC24 Power Contactor, S0, 24 VAC 50/","metaDescription":"Siemens SIRIUS 3RT1026-1CC24 power contactor, size S0, 24 VAC coil 50/60 Hz, 11 kW at 400 V AC-3, screw terminals, snap-on DIN rail, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Contactors"],"specifications":{"Depth":"140 mm","Solid":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²), max. 2x (0.75 ... 4 mm²)","Width":"45 mm","Height":"88 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":"2","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","Design of the surge suppressor":"with varistor","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=488099&mlfb=3RT1026-1CC24","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RT1026-1CC24/alternatives.json"},"ai":{"faq":[{"question":"What wire sizes does the 3RT1026-1CC24 accept on the main and control terminals?","answer":"Main circuit screw terminals accept 2x (1 to 2.5 mm²) or 2x (2.5 to 6 mm²) solid/stranded, max 2x 10 mm².
