For reversing or plugging duty (AC-4), it's rated 15.5 A at 400 V, which is the current it can interrupt during inching or counter-torque stops. The contactor carries a mechanical life of 10 million operations, so it's sized for high-cycle applications like conveyor lines or pump stations where the panel builder needs the S0 footprint (45 mm wide, 85 mm tall, 140 mm deep) to fit a dense DIN-rail layout. ## Mounting and integration — DIN-rail and terminal details The main circuit uses screw-type terminals accepting 2x (1... 2.5 mm²) solid/stranded, 2x (2.5... 6 mm²), or max 2x 10 mm²; auxiliary and control circuit terminals accept 2x (0.5... 1.5 mm²), 2x (0.75... 2.5 mm²), or max 2x (0.75... 4 mm²). AWG equivalents: main contacts 2x (16... 12), 2x (14... 10), 1x 8; auxiliary contacts 2x (20... 16), 2x (18... 14), 1x 12. IP20 on the front, IP00 at the terminals — so the terminal area needs enclosure protection if washdown or dust ingress is a concern. ## Coordination and protection — fuse sizing for Type 1 and Type 2 These are the values the panel designer needs for the SCCR calculation upstream — the 25 A Type 2 limit is the tighter constraint and governs the branch circuit protection if you want to avoid replacing the contactor after a fault. ## Auxiliary contact ratings and ambient limits Auxiliary contacts rated 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V — these are the making/breaking capacities for the control circuit, not the main power path.","metaTitle":"Siemens 3RT1025-1AP64 SIRIUS Power Contactor, S0 Frame, 690V","metaDescription":"Siemens 3RT1025-1AP64 SIRIUS power contactor, S0 size, 11 kW at 690 V AC-3, 15.5 A AC-4, screw terminals, IP20 front, current production, sourced to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Contactors"],"specifications":{"Depth":"140 mm","Solid":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²), max. 2x (0.75 ... 4 mm²)","Width":"45 mm","Height":"85 mm","at 50 Hz":"0.8 ... 1.1","at 60 Hz":"0.8 ... 1.1","On The Front":"IP20","1 Rated Value":"50 Hz","2 Rated Value":"60 Hz","Of The Terminal":"IP00","lifecycle_stage":"current","Fastening Method":"screw and snap-on mounting onto 35 mm standard mounting rail according to DIN EN 50022","Size Of Contactor":"S0","Solid Or Stranded":"2x (1 ... 2,5 mm²), 2x (2,5 ... 6 mm²), max. 2x 10 mm²","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":"220 V","at 500 V rated value":"10 kW","at 60 Hz rated value":"240 V","at 690 V rated value":"11 kW","Side-By-Side Mounting":"Yes","For Main Current Circuit":"screw-type terminals","at AC-2 at 400 V rated value":"7.5 kW","at AC-4 at 400 V rated value":"15.5 A","at AWG cables for main contacts":"2x (16 ... 12), 2x (14 ... 10), 1x 8","For Auxiliary And Control Circuit":"screw-type terminals","With Type Of Assignment 2 Required":"fuse gL/gG: 25 A","reference code acc. to IEC 81346-2":"Q","Ambient Temperature During Operation":"-25 ... +60 °C","With Type Of Coordination 1 Required":"fuse gL/gG: 63 A","at AWG cables for auxiliary contacts":"2x (20 ... 16), 2x (18 ... 14), 1x 12","operational current at AC-12 maximum":"10 A","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","Contact Reliability Of Auxiliary Contacts":"1 faulty switching per 100 million (17 V, 1 mA)","apparent holding power of magnet coil at AC":"7.5 V·A","apparent pick-up power of magnet coil at AC":"69 V·A","Type Of Voltage Of The Control Supply Voltage":"AC","Required Spacing For Grounded Parts At The Side":"6 mm","Inductive Power Factor With Closing Power Of The Coil":"0.76","Installation Altitude At Height Above Sea Level Maximum":"2 000 m","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","number of NC contacts for auxiliary contacts instantaneous contact":"2","number of NO contacts for auxiliary contacts instantaneous contact":"2","Of The Contactor With Added Electronically Optimized 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=132806&mlfb=3RT1025-1AP64","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RT1025-1AP64/alternatives.json"},"ai":{"faq":[{"question":"Who supplies 3RT1025-1AP64 and how is it quoted for volume purchases?","answer":"Sourced to order against an RFQ through independent distribution channels.

The 3RT1025-1AP64 has a higher AC-3 rating (11 kW at 690 V vs the smaller frame's rating), so it's a functional upgrade in current capacity — but verify the control voltage and auxiliary contact configuration match your circuit before swapping, as the terminal assignments are the same screw-type layout."},{"question":"What compliance documentation does Siemens provide for 3RT1025-1AP64?","answer":"As a SIRIUS catalog product, it carries IEC 60947-4-1 compliance for contactors and motor starters.
