The contactor measures 210 mm high by 145 mm wide by 202 mm deep and is fixed via screw mounting. This is the 110–127 V AC 50/60 Hz coil variant, drawing 6 A at 24 V rated value and 6 A at 230 V rated value. Pollution degree 3 rating means it handles conductive pollution environments typical in industrial control panels. ## Switching Performance and Duty Ratings Electrical switching frequency varies by duty: AC-1 maximum 750 operations per hour, AC-3 and AC-3e maximum 500 operations per hour, AC-4 maximum 130 operations per hour. General AC and DC switching is rated at 2 000 operations per hour. The AC-3e rated maximum voltage is 1 000 V, matching the insulation voltage. This covers the 690 V rating where the contactor delivers 112 kW, and the 400 V 60 °C rating of 197 kW. Auxiliary contact ratings: 6 A at 24 V, 1 A at 110 V, 0.3 A at 220 V, 6 A at 230 V, 3 A at 400 V. Minimum permissible conductor cross-section is 185 mm² at both 40 °C and 60 °C, sized for the full rated current.","metaTitle":"Siemens 3RT5066-6AF36 SIRIUS S10 Power Contactor, 197 kW at","metaDescription":"Siemens 3RT5066-6AF36 SIRIUS S10 power contactor, 197 kW at 400 V 60 °C, 1000 V insulation voltage, screw terminals, varistor surge suppression, active production, RoHS compliant.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Contactors"],"specifications":{"Depth":"202 mm","Width":"145 mm","at AC":"2 000 1/h","at DC":"2 000 1/h","Height":"210 mm","at 50 Hz":"0.9","at 60 Hz":"0.9","Rated Value":"110 ... 127 V","During Storage":"-55 ... +80 °C","at AC-1 maximum":"750 1/h","at AC-3 maximum":"500 1/h","at AC-4 maximum":"130 1/h","lifecycle_stage":"current","During Operation":"-25 ... +60 °C","Fastening Method":"screw fixing","at AC-3e maximum":"500 1/h","Mounting Position":"with vertical mounting surface +/-90° rotatable, with vertical mounting surface +/- 22.5° tiltable to the front and back","Size Of Contactor":"S10","Product Brand Name":"SIRIUS","Degree Of Pollution":"3","Product Designation":"Power contactor","at 24 V rated value":"6 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":"110 ... 127 V","at 60 Hz rated value":"110 ... 127 V","at 690 V rated value":"112 kW","Side-By-Side Mounting":"Yes","For Main Current Circuit":"screw-type terminals","at AC-3e rated value maximum":"1 000 V","Substance Prohibitance (Date)":"03/01/2017","at 40 °C minimum permissible":"185 mm²","at 60 °C minimum permissible":"185 mm²","Design Of The Surge Suppressor":"with varistor","Insulation Voltage Rated Value":"1 000 V","at 230 V at 60 °C rated value":"113 kW","at 400 V at 60 °C rated value":"197 kW","at 690 V at 60 °C rated value":"340 kW","at AWG cables for main contacts":"2/0 ... 500 kcmil","For Auxiliary And Control Circuit":"screw-type terminals","Product Extension Auxiliary Switch":"Yes","With Type Of Assignment 2 Required":"fuse gL/gG: 400 A","closing power of magnet coil at DC":"650 W","holding power of magnet coil at DC":"7.4 W","Surge Voltage Resistance Rated Value":"8 kV","With Type Of Coordination 1 Required":"fuse gL/gG: 500 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","at ambient temperature 40 °C rated value":"330 A","at ambient temperature 60 °C rated value":"300 A","Type Of Voltage Of The Control Supply Voltage":"AC/DC","Installation Altitude At Height Above Sea Level Maximum":"2 000 m","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"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.aoctrl.com/cb327ca2e60aa733297d7117a3b70541.pdf","sourceUrl":"https://support.industry.siemens.com/webbackend/api/ProductSupport/TechnicalData?language=en&region=cn&productId=580298&mlfb=3RT5066-6AF36","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RT5066-6AF36/alternatives.json"},"ai":{"faq":[{"question":"Does 3RT5066-6AF36 include surge suppression?","answer":"Yes, the surge suppressor design is a varistor, integrated into the contactor."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT5066-6AF36","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RT5066-6AF36 when reusing this data.
