Main power terminals accept 25 to 120 mm² stranded copper, so the lugging matches cable sizes typical of 100 A+ motor feeders. The coil terminals are also screw-type, which means a standard Pozidriv or flathead on the panel floor — no special tooling needed. ## Duty-cycle and switching capability At AC-3 (squirrel-cage motor starting), the contactor is good for 750 cycles per hour; at AC-4 (plugging or inching), that drops to 130 cycles per hour. The arcing time sits between 10 and 15 ms, and the opening delay for both AC and DC coils is 40 to 60 ms — consistent timing for coordinated starter assemblies. The auxiliary contact block is integrated, rated 10 A at 24 V, 2 A at 48 V or 60 V, and 1 A at 110 V. ## Clearance and panel integration The contactor is 170 mm deep. Mounting is via a single 9 mm hole with screw fixing.","metaTitle":"Siemens 3RT1056-6AS36 SIRIUS Power Contactor, S6, 120 mm","metaDescription":"Siemens SIRIUS 3RT1056-6AS36 power contactor, size S6, 172 x 120 x 170 mm, screw fixing, 25-120 mm² stranded main terminals, auxiliary switch included, current lifecycle stage.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Contactors"],"specifications":{"Depth":"170 mm","Solid":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²), max. 2x (0.75 ... 4 mm²)","Width":"120 mm","at AC":"40 ... 60 ms","at DC":"40 ... 60 ms","title":"3RT1056-6AS36","Height":"172 mm","Upwards":"10 mm","Forwards":"20 mm","Stranded":"25 ... 120 mm²","at 50 Hz":"0.8","at 60 Hz":"0.8","Downwards":"10 mm","Arcing Time":"10 ... 15 ms","At The Side":"10 mm","Rated Value":"500 ... 550 V","description":"power contactor, AC-3e/AC-3 185 A, 90 kW / 400 V AC (50-60 Hz) / DC Uc: 500-550 V 3-pole, auxiliary contacts 2 NO + 2 NC 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":"300 1/h","at AC-3 maximum":"750 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":"750 1/h","Diameter Of Holes":"9 mm","Mounting Position":"with vertical mounting surface +/-90° rotatable, with vertical mounting surface +/- 22.5° tiltable to the front and back","Size Of Contactor":"S6","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":"30 hp","at 400 V rated value":"3 A","at 440 V rated value":"1.4 A","at 480 V rated value":"180 A","at 50 Hz rated value":"500 ... 550 V","at 500 V rated value":"2 A","at 60 Hz rated value":"500 ... 550 V","at 600 V rated value":"192 A","at 690 V rated value":"1 A","Side-By-Side Mounting":"Yes","at 1000 V rated value":"90 kW","For Auxiliary Contacts":"18 ... 14","Width Of Connection Bar":"17 mm","For Main Current Circuit":"Connection bar","at 200/208 V rated value":"60 hp","at 220/230 V rated value":"75 hp","at 460/480 V rated value":"150 hp","at 575/600 V rated value":"200 hp","Relative Humidity Minimum":"10 %","Of Main Circuit Rated Value":"8 kV","Thickness Of Connection Bar":"3 mm","at AC-3 rated value maximum":"1 000 V","at AC in hot operating state":"39 W","at AC-3e rated value maximum":"1 000 V","at AC-4 at 400 V rated value":"160 A","safety-related switching OFF":"Yes","Substance Prohibitance (Date)":"05/01/2012","Design Of The Surge Suppressor":"with varistor","at AWG cables for main contacts":"4 ... 250 kcmil","Of Auxiliary Circuit Rated Value":"6 kV","at AC-5a up to 690 V rated value":"189 A","at AC-5b up to 400 V rated value":"153 A","For Auxiliary And Control Circuit":"screw-type terminals","Function Module For Communication":"No","With Type Of Assignment 2 Required":"gG: 315 A (690 V, 100 kA), aM: 200 A (690 V, 50 kA), BS88: 315 A (415 V, 50 kA)","Without Load Current Share Typical":"5.2 W","closing power of magnet coil at DC":"360 W","holding power of magnet coil at DC":"5.2 W","At Contactor For Auxiliary Contacts":"Screw-type terminals","With Type Of Coordination 1 Required":"gG: 355 A (690 V, 100 kA)","at AWG cables for auxiliary contacts":"2x (20 ... 16), 2x (18 ... 14), 1x 12","operational current at AC-12 maximum":"10 A","at AC in hot operating state per pole":"13 W","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":"2 900 A;
