That covers most three-phase motor circuits up to about 2.2 kW at 400 V — a common size for small conveyors, pumps, or fans. The contactor is rated for 800 switching cycles per hour under AC-3 duty, dropping to 250 cycles/h under AC-4 (plugging / inching). If your application calls for frequent jogging, that AC-4 limit is the one to watch. Both the front and terminal areas carry an IP20 rating, meaning finger-safe terminals — fine for enclosed panels, but not for washdown environments. The coil draws 0.82 W on closing and holds at 0.24 W DC, so the control transformer can be sized modestly. Auxiliary contacts are rated for PLC-level signals — the spec calls out acceptability for 17 V, 5 mA, so you can wire them directly to a digital input without worrying about contact wetting. Shock resistance is 12.5g at 5 ms and 7.8g at 10 ms, which covers most industrial panel applications short of heavy stamping presses. ## Fuse coordination and compliance The insulation voltage rating is 690 V, matching the AC-3 max.","metaTitle":"Siemens 3RT7027-1AG05 SIRIUS Contactor, 3-pole, AC-3 690 V,","metaDescription":"Siemens 3RT7027-1AG05 SIRIUS contactor, size S0, 3 NO main contacts, AC-3 rated 690 V, screw terminals, IP20, active production, available to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Contactors"],"specifications":{"Depth":"91 mm","Width":"55 mm","Height":"85.5 mm","at 50 Hz":"0.24","at 60 Hz":"0.24","On The Front":"IP20","During Storage":"-25 ... +70 °C","Of The Terminal":"IP20","at AC-3 maximum":"800 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":"800 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":"S0","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":"36 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: 50 A","closing power of magnet coil at DC":"0.82 W","holding power of magnet coil at DC":"0.24 W","Surge Voltage Resistance Rated Value":"6 kV","With Type Of Coordination 1 Required":"gL/gG NH 3NA: 125 A","shock resistance with sine pulse at AC":"12.5g / 5 ms, 7.8g / 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":"1","Connectable Conductor Cross-Section For Main Contacts Finely Stranded With Core End Processing":"6 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":"https://cdn.aoctrl.com/005a6637a83cfe051d51805a80a873fb.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=1533991&mlfb=3RT7027-1AG05","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RT7027-1AG05/alternatives.json"},"ai":{"faq":[{"question":"What is the depth of 3RT7027-1AG05?","answer":"The listed depth is 91 mm, width 55 mm, height 85.5 mm."},{"question":"What compliance documentation does this brand provide for 3RT7027-1AG05?","answer":"The contactor carries IP20 finger-safe protection and is rated for pollution degree 3 and 6 kV surge voltage.
