The 24 VDC coil pulls in reliably across the 0.8 to 1.1 x Us range at 50/60 Hz. Spring-loaded terminals on the main circuit accept 2x (0.25 to 2.5 mm²) solid or stranded — no screw torque to verify, which speeds panel wiring. For reversing or plugging duty (AC-4), the contactor is rated 8.5 A at 400 V, which is the figure to use when the load cycles direction under full load. The S00 frame (45 mm wide, 60 mm tall, 73 mm deep) snaps onto 35 mm DIN rail per EN 50022. Side-by-side mounting is permitted with 6 mm spacing at the side, which keeps the panel fill factor tight. Type 1 coordination allows a 35 A fuse.","metaTitle":"Siemens 3RT1016-2AP02 SIRIUS Contactor, S00, 4 kW at 400 V","metaDescription":"Siemens SIRIUS 3RT1016-2AP02 power contactor, size S00, 4 kW at 400 V AC-3, spring-loaded terminals, 24 VDC coil, current production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Contactors"],"specifications":{"Depth":"73 mm","Solid":"2x (0.25 ... 2.5 mm²)","Width":"45 mm","Height":"60 mm","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 400 V rated value":"4 kW","at 50 Hz rated value":"230 V","at 500 V rated value":"4.5 kW","at 60 Hz rated value":"230 V","at 690 V rated value":"5.5 kW","Instantaneous Contact":"0","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","With Type Of Assignment 2 Required":"fuse gL/gG: 20 A","operating current at AC-12 maximum":"10 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","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","Finely Stranded Without Core End Processing":"2x (0.25 ... 2.5 mm²)","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","operating current at AC-15 at 230 V rated value":"6 A","operating current at AC-15 at 400 V rated value":"3 A","Inductive Power Factor With Closing Power Of The Coil":"0.8","Installation Altitude At Height Above Sea Level Maximum":"2 000 m","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","type of connectable conductor cross-sections at AWG conductors for auxiliary contacts":"2x (24 ... 14)"}},"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=261869&mlfb=3RT1016-2AP02","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RT1016-2AP02/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional alternative to the 3RT1016-2AP02?","answer":"The 3RT1017-1AP01 is a higher-rated S00 contactor (7 kW at 400 V AC-3) with the same 24 VDC coil and spring-loaded terminals. It is a direct mechanical and electrical swap in the same DIN footprint — no rewiring needed — but carries a higher motor rating if your load requires it."},{"question":"What compliance documentation is available for this contactor?","answer":"The SIRIUS series carries CE marking for the European market and is designed to meet IEC/EN 60947-4-1. RoHS and REACH declarations are standard from Siemens for current-production parts. UL and CSA listings are typical for the SIRIUS line, though the specific file number is not in this record."},{"question":"Will the 3RT1016-2AP02 drop into a panel specified for the 3RT1017-1AP01?","answer":"Yes. Both are size S00 with the same 45 mm width, 35 mm DIN-rail mounting, and spring-loaded terminals. The 3RT1016-2AP02 is a lower current rating (4 kW vs 7 kW at 400 V AC-3), so it fits the same physical space and wiring scheme."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT1016-2AP02","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RT1016-2AP02 when reusing this data.
