This contactor is rated for motor duty at 4.5 kW at 500 V and 5.5 kW at 690 V, with an AC-2 rating of 4 kW at 400 V and an AC-4 rating of 8.5 A at 400 V — the AC-4 figure governs the switching of inching or reversing loads where the contactor makes and breaks the motor current under full load. Pollution degree 3 is declared, meaning the part is suitable for industrial atmospheres with conductive or dry non-conductive pollution. As a SIRIUS component, full compliance documentation — including RoHS, REACH, and the EU Declaration of Conformity — is available from Siemens. The contactor carries the CE mark and is designed to meet IEC 60947-4-1 for contactors and motor-starters. ## Coordination and Auxiliary Contacts These values are critical for selectivity studies in a distribution board. The contactor carries one normally open instantaneous auxiliary contact rated at 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V — sufficient for feedback to a PLC or to seal in a holding circuit. ## Physical Integration Dimensions are 45 mm wide, 60 mm tall, and 114 mm deep — the depth is the dimension behind the panel face when DIN-rail mounted. The spring-loaded terminals on the main circuit accept 2x (0.25 to 2.5 mm²) or 2x (24 to 14 AWG) conductors. No screw torque specification is needed — the spring cage provides consistent clamping force independent of the installer.","metaTitle":"Siemens 3RT1016-2AF04 SIRIUS Power Contactor, Size S00, 4.5","metaDescription":"Siemens 3RT1016-2AF04 SIRIUS power contactor, Size S00, 4.5 kW at 500 V / 5.5 kW at 690 V, AC-2/AC-4 rated, spring-loaded terminals, IP20, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Contactors"],"specifications":{"Depth":"114 mm","Solid":"2x (0.25 ... 2.5 mm²)","Width":"45 mm","Height":"60 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":"110 V","at 500 V rated value":"4.5 kW","at 60 Hz rated value":"110 V","at 690 V rated value":"5.5 kW","Instantaneous Contact":"2","Side-by-side mounting":"Yes","For Main Current Circuit":"spring-loaded terminals","Single Or Multi-Stranded":"2x (0,25 ... 2,5 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 (24 ... 14)","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 (0.25 ... 1.5 mm²)","Number of poles for main current circuit":"3","at AWG conductors for auxiliary contacts":"2x (24 ... 14)","Contact reliability of auxiliary contacts":"1 faulty switching per 100 million (17 V, 1 mA)","For Auxiliary And Control Current Circuit":"spring-loaded 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","Finely Stranded Without Core End Processing":"2x (0.25 ... 2.5 mm²)","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=439645&mlfb=3RT1016-2AF04","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RT1016-2AF04/alternatives.json"},"ai":{"faq":[{"question":"What are the key motor ratings for this contactor?","answer":"It is rated at 4.5 kW at 500 V and 5.5 kW at 690 V.
