The S10 frame is the largest standard size in the SIRIUS 3RT series, designed for high-current motor loads and heavy-duty switching applications. The main circuit accepts stranded conductors from 70 to 240 mm², which covers the cable range for motors in the 75-200 kW class on 400 V three-phase systems. ## Mounting and integration constraints Mounting is by screw fixing, not DIN rail — the S10 frame is too heavy for a snap-on foot. The contactor occupies 210 mm height, 145 mm width, and 202 mm depth, so plan for a backplate or sub-panel with clearance. The mounting position allows rotation ±90° on a vertical surface and tilting ±22.5° forward or back, which gives flexibility in tight enclosures. These are minimum air gaps for arc flash and heat dissipation — respect them in the panel layout. ## Switching frequency and duty class — what the ratings mean The contactor's switching frequency depends on the duty class. At AC-1 (resistive loads) it manages 800 operations per hour; at AC-3 (standard motor starting) it's 500 per hour; at AC-4 (plugging/inching) it drops to 130 per hour. The AC-3e rating matches the AC-3 figure at 500 per hour. These limits govern thermal rise in the arc chamber — exceeding them accelerates contact wear. If your cycle requires faster jogging or reversing, the AC-4 limit of 130 ops/hour (one every 27.7 seconds) is the binding constraint. ## Operating conditions and auxiliaries The coil holds at 220-240 V AC nominal; the pickup dropout ratio is 0.8 of rated voltage for initial pull-in and 1.1 for the full-scale holding voltage. An auxiliary switch is built in, which saves an add-on block for basic status feedback. Auxiliary contact ratings at 24 V are 10 A, dropping to 2 A at 48 V and 60 V, and 1 A at 110 V — standard de-rating for DC inductive loads.","metaTitle":"Siemens SIRIUS 3RT1065-6AP36-3PA0 Power Contactor, S10, 220-","metaDescription":"Siemens SIRIUS 3RT1065-6AP36-3PA0 power contactor, size S10, 220-240V AC coil, screw terminals, active production, sourced to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Contactors"],"specifications":{"Depth":"202 mm","Solid":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²), max. 2x (0.75 ... 4 mm²)","Width":"145 mm","at AC":"40 ... 80 ms","at DC":"40 ... 80 ms","title":"3RT1065-6AP36-3PA0","Height":"210 mm","Upwards":"10 mm","Forwards":"20 mm","Stranded":"70 ... 240 mm²","at 50 Hz":"0.9","at 60 Hz":"0.9","Downwards":"10 mm","Arcing Time":"10 ... 15 ms","At The Side":"10 mm","Rated Value":"220 ... 240 V","description":"power contactor, AC-3e/AC-3 265 A, 132 kW / 400 V AC (50-60 Hz) / DC Uc: 220-240 V 3-pole, auxiliary contacts 2 NO + 2 NC permanently mounted drive: conventional main circuit: busbar control and auxiliary circuit: screw terminal","Initial Value":"0.8","During Storage":"-55 ... +80 °C","Of Magnet Coil":"Screw-type terminals","Number Of Holes":"1","at AC-1 maximum":"800 1/h","at AC-2 maximum":"250 1/h","at AC-3 maximum":"500 1/h","at AC-4 maximum":"130 1/h","lifecycle_stage":"current","Auxiliary Switch":"Yes","During Operation":"-25 ... +60 °C","Fastening Method":"screw fixing","Full-Scale Value":"1.1","at AC-3e maximum":"500 1/h","Diameter Of Holes":"11 mm","Mounting Position":"with vertical mounting surface +/-90° rotatable, with vertical mounting surface +/- 22.5° tiltable to the front and back","Size Of Contactor":"S10","Solid Or Stranded":"2x (0,5 ... 1,5 mm²), 2x (0,75 ... 2,5 mm²), max. 2x (0,75 ... 4 mm²)","Product Brand Name":"SIRIUS","Product Designation":"Power contactor","at 24 V rated value":"10 A","at 48 V rated value":"2 A","at 60 V rated value":"2 A","Of Contactor Typical":"10 000 000","at 110 V rated value":"1 A","at 125 V rated value":"0.9 A","at 220 V rated value":"0.3 A","at 230 V rated value":"6 A","at 400 V rated value":"3 A","at 440 V rated value":"1.4 A","at 480 V rated value":"240 A","at 50 Hz rated value":"220 ... 240 V","at 500 V rated value":"2 A","at 60 Hz rated value":"220 ... 240 V","at 600 V rated value":"242 A","at 690 V rated value":"1 A","Side-By-Side Mounting":"Yes","at 1000 V rated value":"132 kW","For Auxiliary Contacts":"18 ... 14","Width Of Connection Bar":"25 mm","For Main Current Circuit":"Connection bar","at 200/208 V rated value":"75 hp","at 220/230 V rated value":"100 hp","at 460/480 V rated value":"200 hp","at 575/600 V rated value":"250 hp","Relative Humidity Minimum":"10 %","Of Main Circuit Rated Value":"8 kV","Safety-Related Switching On":"Yes","Thickness Of Connection Bar":"6 mm","at AC-3 rated value maximum":"1 000 V","at AC in hot operating state":"54 W","at AC-2 at 400 V rated value":"132 kW","at AC-3e rated value maximum":"1 000 V","at AC-4 at 400 V rated value":"230 A","safety-related switching OFF":"Yes","Substance Prohibitance (Date)":"05/01/2012","Design Of The Surge Suppressor":"with varistor","Of Auxiliary Circuit Rated Value":"6 kV","at AC-5a up to 690 V rated value":"290 A","at AC-5b up to 400 V rated value":"219 A","For Auxiliary And Control Circuit":"screw-type terminals","Function Module For Communication":"No","With Type Of Assignment 2 Required":"gG: 400 A (690 V, 100 kA), aM: 315 A (690 V, 50 kA), BS88: 400 A (415 V, 50 kA)","Without Load Current Share Typical":"7.4 W","closing power of magnet coil at DC":"650 W","holding power of magnet coil at DC":"7.4 W","At Contactor For Auxiliary Contacts":"Screw-type terminals","With Type Of Coordination 1 Required":"gG: 500 A (690 V, 100 kA)","operational current at AC-12 maximum":"10 A","at AC in hot operating state per pole":"18 W","for AWG cables for auxiliary contacts":"2x (20 ... 16), 2x (18 ... 14), 1x 12","number of NO contacts for main contacts":"3","reference code according to IEC 81346-2":"Q","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)","mirror contact according to IEC 60947-4-1":"Yes","Type Of Voltage Of The Control Supply Voltage":"AC/DC","Limited To 1 S Switching At Zero Current Maximum":"4 880 A;
