The coil operates across 0.8...1.1 × rated voltage at 50 Hz and 0.85...1.1 at 60 Hz, with a rated control supply of 100 V at 50 Hz or 100...110 V at 60 Hz. ## Mounting and Integration – DIN Rail, Clearance, and Fill Factor Side-by-side mounting is permitted, with 6 mm clearance needed at the side for heat dissipation. IP20 on the front, IP00 at the terminals — the contactor is meant for enclosed panels, not open washdown zones. Screw terminals accept 2x (0.25...2.5 mm²) solid or stranded, up to 2x 10 mm² maximum. For AWG, that's 2x (16...12) solid or 2x (14...10) stranded, with a single 8 AWG max. Strip and torque per the nameplate — no special tooling needed beyond a standard screwdriver. ## Lifecycle and Sourcing – Active Production, Standard Channel Short-circuit coordination is specified: type 2 requires a 25 A gL/gG fuse; type 1 allows up to 63 A gL/gG. This matters when the contactor sits upstream of a motor starter — the fuse size determines whether the contactor survives a fault or needs replacement.","metaTitle":"Siemens 3RT1025-3AG60 SIRIUS Power Contactor, S0 Frame, 7.5","metaDescription":"Siemens 3RT1025-3AG60 SIRIUS power contactor, S0 size, 7.5 kW AC-2 at 400 V, 45 mm wide, screw terminals, active production, available to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Contactors"],"specifications":{"Depth":"90 mm","Solid":"2x (0.25 ... 2.5 mm²)","Width":"45 mm","Height":"85 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":"100 V","at 500 V rated value":"10 kW","at 60 Hz rated value":"100 ... 110 V","at 690 V rated value":"11 kW","Instantaneous Contact":"0","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":"7.5 kW","at AC-4 at 400 V rated value":"15.5 A","Operating current at AC-12 maximum":"10 A","With Type Of Assignment 2 Required":"fuse gL/gG: 25 A","at AWG conductors for main contacts":"2x (16 ... 12), 2x (14 ... 10), 1x 8","With Type Of Coordination 1 Required":"fuse gL/gG: 63 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":"40 A","Apparent holding power of magnet coil at AC":"7.5 V·A","Apparent pick-up power of magnet coil at AC":"69 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":"0.76","Inductive power factor with the holding power of the coil":"0.28","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=326683&mlfb=3RT1025-3AG60","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RT1025-3AG60/alternatives.json"},"ai":{"faq":[{"question":"What is the AC-2 motor rating for 3RT1025-3AG60?","answer":"The AC-2 rating at 400 V is 7.5 kW.
