It ships with screw-type terminals for both main and control circuits — no auxiliary contact block on board, but the product extension slot accepts one. The kit is complete for a basic three-pole switching job: the contactor itself, the terminal hardware, and the DIN-rail clip. No holes in the box for a standard panel build. The 45 mm width and 72 mm depth fit the S00 footprint — three units side-by-side without spacing gaps. ## Coil and control circuit — what the DC rating means The magnet coil draws 0.8 W during closing and holds at 0.27 W DC — a low-hold design that keeps the control transformer or PLC output lightly loaded once the contactor is sealed. The 48 V AC 50/60 Hz coil means this variant is wound for standard control voltages in many European and Asian panels; if your BOM calls for 24 V DC or 230 V AC, this is not the right coil code. Switching frequency is rated at 750 cycles per hour under AC-3 duty and 250 cycles per hour under AC-4 — the AC-4 figure governs frequent plugging or inching applications. ## Terminal specs and coordination Screw terminals accept solid or stranded wire: 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) per clamp, with the same range for finely stranded wire with ferrule. For short-circuit coordination, type 1 requires a 35 A gL/gG NH fuse; type 2 requires a 20 A gL/gG NH fuse. The IP20 rating on both front and terminal faces means finger-safe when installed in a closed panel — no touch-hazard exposure during normal operation.","metaTitle":"Siemens 3RT7017-1AH02 Contactor, Size S00, 3-Pole, IP20","metaDescription":"Siemens 3RT7017-1AH02 Size S00 contactor, 3 NO main contacts, 45 mm wide, IP20 terminals, screw and snap-on DIN rail mounting.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Contactors"],"specifications":{"Depth":"72 mm","Width":"45 mm","Height":"57.5 mm","at 50 Hz":"0.27","at 60 Hz":"0.27","On The Front":"IP20","During Storage":"-25 ... +70 °C","Of The Terminal":"IP20","at AC-3 maximum":"750 1/h","at AC-4 maximum":"250 1/h","lifecycle_stage":"current","During Operation":"-10 ... +55 °C","Fastening Method":"screw and snap-on mounting onto 35 mm DIN rail according to DIN EN 50022","at AC-3e maximum":"750 1/h","Mounting Position":"+/-180° rotation possible on vertical mounting surface; can be tilted forward and backward by +/- 22.5° on vertical mounting surface","Size Of Contactor":"S00","Solid Or Stranded":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²)","Degree Of Pollution":"3","at 230 V rated value":"6 A","at 400 V rated value":"3 A","at 50 Hz rated value":"48 V","at 60 Hz rated value":"48 V","at 690 V rated value":"1 A","Side-By-Side Mounting":"Yes","For Main Current Circuit":"screw-type terminals","at AC-3 rated value maximum":"690 V","at AC-3e rated value maximum":"690 V","Insulation Voltage Rated Value":"690 V","For Auxiliary And Control Circuit":"screw-type terminals","Product Extension Auxiliary Switch":"Yes","With Type Of Assignment 2 Required":"gL/gG NH 3NA: 20 A","closing power of magnet coil at DC":"0.8 W","holding power of magnet coil at DC":"0.27 W","Surge Voltage Resistance Rated Value":"6 kV","With Type Of Coordination 1 Required":"gL/gG NH 3NA: 35 A","shock resistance with sine pulse at AC":"9.8g / 5 ms, 5.9g / 10 ms","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":"acceptability for PLC control (17 V, 5 mA)","Type Of Voltage Of The Control Supply Voltage":"AC","operational current at DC-13 at 220 V rated value":"0.3 A","Installation Altitude At Height Above Sea Level Maximum":"2 000 m","Required Spacing With Side-By-Side Mounting At The Side":"0 mm","For Short-Circuit Protection Of The Auxiliary Switch Required":"fuse gL/gG: 10 A","number of NC contacts for auxiliary contacts instantaneous contact":"1","number of NO contacts for auxiliary contacts instantaneous contact":"0","Connectable Conductor Cross-Section For Main Contacts Finely Stranded With Core End Processing":"2.5 mm²","Connectable Conductor Cross-Section For Auxiliary Contacts Finely Stranded With Core End Processing":"0.5 ... 2.5 mm²"}},"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=1533890&mlfb=3RT7017-1AH02","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RT7017-1AH02/alternatives.json"},"ai":{"faq":[{"question":"Does the 3RT7017-1AH02 have a normally closed auxiliary contact?","answer":"No. The main contacts are three normally-open poles.
