The auxiliary contact block supports a 230 V rated current of 6 A, 400 V at 3 A, and 690 V at 1 A — these are the switching limits for control or signaling circuits, not the main motor path. ## Mechanical integration and mounting Side-by-side mounting is permitted, so multiple contactors can pack tightly on the rail without mandatory spacing. Dimensions are 115 mm deep, 55 mm wide, 112 mm high — the S2 frame size keeps the footprint compact for a 3-pole contactor in this current class. ## Coil and control supply Coil draw is 0.36 A at 50 Hz and 0.38 A at 60 Hz. Closing power is 0.76 W DC; holding power drops to 0.35 W DC, which means the coil driver sees a brief inrush then a lower steady-state load. ## Switching frequency and environmental limits Maximum switching rate is 800 operations per hour under AC-3 duty and 250 per hour under AC-4 duty — AC-4 (plugging/inching) generates more arc wear, so the lower limit is the one to respect for frequent reversing or jogging applications. ## Short-circuit coordination and wiring These are the fuse sizes to specify when designing the branch circuit. Terminal wiring accepts 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded, and finely stranded with ferrules — covers standard panel wire sizes.","metaTitle":"Siemens 3RT7036-1AG20 Contactor, Size S2, 3-Pole, 690V AC-3,","metaDescription":"Siemens 3RT7036-1AG20 Size S2 contactor, 3-pole, 690V AC-3 max, 110V 50/60Hz coil, screw terminals, IP20 front, DIN rail mount, current production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Contactors"],"specifications":{"Depth":"115 mm","Width":"55 mm","Height":"112 mm","at 50 Hz":"0.36","at 60 Hz":"0.38","On The Front":"IP20","During Storage":"-25 ... +70 °C","Of The Terminal":"IP00","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 standard mounting rail according to DIN EN 50022","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":"S2","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":"110 V","at 60 Hz rated value":"110 V","at 690 V rated value":"1 A","Side-By-Side Mounting":"Yes","For Main Current Circuit":"screw-type terminals","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: 80 A","closing power of magnet coil at DC":"0.76 W","holding power of magnet coil at DC":"0.35 W","Surge Voltage Resistance Rated Value":"6 kV","With Type Of Coordination 1 Required":"gL/gG NH 3NA: 160 A","shock resistance with sine pulse at AC":"15g / 5 ms, 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","operating voltage at AC-3 rated value maximum":"690 V","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":"0","number of NO contacts for auxiliary contacts instantaneous contact":"0","Connectable Conductor Cross-Section For Main Contacts Finely Stranded With Core End Processing":"25 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=1534073&mlfb=3RT7036-1AG20","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RT7036-1AG20/alternatives.json"},"ai":{"faq":[{"question":"What are the key dimensions of the 3RT7036-1AG20?","answer":"Depth is 115 mm, width is 55 mm, and height is 112 mm.
