The AC-4 inching/plugging rating is 8.5 A at 400 V, so if your application does frequent reversing or jogging, that's the current limit per operation. The maximum operating current in AC-12 (resistive load) is 10 A, which is the ceiling for general-purpose switching of heaters or lighting banks. The main circuit uses spring-loaded terminals accepting 2x (0.25... 2.5 mm²) solid or stranded, or 2x (24... 14) AWG — no screw torque to verify, which saves time on the wireman's side. ## Coil and Control Circuit Details The auxiliary contact block has one instantaneous contact (NO or NC depending on variant). This matters when you're specifying the branch circuit protection for a motor starter combination. Side-by-side mounting is permitted with 6 mm spacing at the side, so you can pack contactors tightly on the rail.","metaTitle":"Siemens 3RT1016-2BG41 SIRIUS Contactor, S00, 4 kW AC-2 at 40","metaDescription":"Siemens 3RT1016-2BG41 SIRIUS power contactor, size S00, 4 kW AC-2 at 400 V, 10 A AC-12 max, spring-loaded terminals, current production status.","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","Maximum":"2 000 m","At The Side":"6 mm","Rated Value":"125 V","On The Front":"IP20","Initial Value":"0.85","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","Full-scale value":"1.1","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 500 V rated value":"4.5 kW","at 690 V rated value":"5.5 kW","Instantaneous Contact":"1","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","Closing power of magnet coil at DC":"3.3 W","Holding power of magnet coil at DC":"3.3 W","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","Finely Stranded Without Core End Processing":"2x (0.25 ... 2.5 mm²)","Type of voltage of the control supply voltage":"DC","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=337427&mlfb=3RT1016-2BG41","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RT1016-2BG41/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional alternative to the 3RT1016-2BG41?","answer":"The 3RT1015-1BB42 is a smaller-frame S00 contactor but with screw terminals instead of spring-loaded.
