The S00 envelope (45 mm wide, 57.5 mm tall, 114 mm deep) is sized for high-density panels: it snaps onto a 35 mm DIN rail per EN 50022 or screws directly to a mounting plate. The AC-3 motor rating is 5.5 kW at 690 V and 4.5 kW at 500 V — that's the load-switching capability for a standard squirrel-cage motor. For resistive loads (AC-1), the contactor handles up to 10 A continuous. The DC coil pulls 10 A at 24 V nominal; it holds in down to about 18 V and drops out below that. Altitude derating applies above 2 000 m. ## Terminal & Wiring Details Main-circuit terminals are screw-type, accepting solid or stranded copper: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²). AWG equivalents are 2x (20 to 16), 2x (18 to 14), or single 12 AWG. For short-circuit protection with type 2 coordination (no welding), use a gL/gG fuse rated 20 A; type 1 coordination allows a 35 A fuse. Side-by-side mounting is permitted with 6 mm spacing to adjacent devices — no extra gap needed for heat dissipation at rated load.","metaTitle":"Siemens 3RT1016-1AU05-ZW95 SIRIUS Contactor, S00, 45mm, 5.5k","metaDescription":"Siemens SIRIUS 3RT1016-1AU05-ZW95 power contactor, size S00, 45mm wide, screw terminals, 5.5 kW at 690 V AC-3, IP20 front, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Contactors"],"specifications":{"Depth":"114 mm","Solid":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²), max. 2x (0.75 ... 4 mm²)","Width":"45 mm","Height":"57.5 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":"IP20","lifecycle_stage":"current","During Operation":"-25 ... +60 °C","Size of contactor":"S00","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":"30 000 000","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":"240 V","at 500 V rated value":"4.5 kW","at 60 Hz rated value":"240 V","at 690 V rated value":"5.5 kW","Instantaneous Contact":"3","Side-by-side mounting":"Yes","For Main Current Circuit":"screw-type terminals","Single Or Multi-Stranded":"2x (0,5 ... 1,5 mm²), 2x (0,75 ... 2,5 mm²), max. 2x (0,75 ... 4 mm²)","at AC-2 at 400 V rated value":"4 kW","at AC-4 at 400 V rated value":"8.5 A","Operating current at AC-12 maximum":"10 A","With Type Of Assignment 2 Required":"fuse gL/gG: 20 A","at AWG conductors for main contacts":"2x (20 ... 16), 2x (18 ... 14), 1x 12","With Type Of Coordination 1 Required":"fuse gL/gG: 35 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":"22 A","Apparent holding power of magnet coil at AC":"4.4 V·A","Apparent pick-up power of magnet coil at AC":"27 V·A","Type of voltage of the control supply voltage":"AC","Inductive power factor with closing power of the coil":"0.8","Inductive power factor with the holding power of the coil":"0.27","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=237690&mlfb=3RT1016-1AU05-ZW95","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RT1016-1AU05-ZW95/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional alternative to the 3RT1016-1AU05-ZW95?","answer":"The 3RT1016-2AP02 is a peer in the same S00 frame but with a 24 V AC coil instead of DC.
