The size S12 frame (214 mm height, 180 mm width, 225 mm depth) is a substantial unit — plan for panel depth and door clearance. Screw fixing through 11 mm holes is the fastening method, so the panel backplate needs drilled holes, not a DIN rail. The coil pulls 200...277 V AC, with opening delays of 80...100 ms on both AC and DC dropout. That timing matters for sequencing — if you need faster drop-out for a safety circuit, this contactor's inherent delay is on the longer side. The arcing time of 10...15 ms is typical for this class. Switching frequency limits are given per duty class: 700 operations/hour at AC-1 (resistive), 500 at AC-3 (motor starting), and 130 at AC-4 (plugging/inching). For a motor starting application at 500 ops/hour, that's roughly one start every 7 seconds — adequate for most conveyor and pump cycles, but not for high-speed indexing. The auxiliary switch is present and rated for 10 A at 24 V, 2 A at 48 V and 60 V, and 1 A at 110 V. Main power terminals accept stranded wire from 70 to 240 mm², suitable for the motor feeder sizes this contactor class typically handles. Auxiliary terminals accept 2x (0.5...1.5 mm²) or 2x (0.75...2.5 mm²) solid or stranded, which covers standard control wiring.","metaTitle":"Siemens 3RT1075-6PP35 SIRIUS Power Contactor, Size S12, 200-","metaDescription":"Siemens SIRIUS 3RT1075-6PP35 power contactor, size S12, screw-type coil terminals 200-277V AC, 10M mechanical cycles, current lifecycle stage, sourced to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Contactors"],"specifications":{"Depth":"225 mm","Solid":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²), max. 2x (0.75 ... 4 mm²)","Width":"180 mm","at AC":"80 ... 100 ms","at DC":"80 ... 100 ms","Height":"214 mm","Upwards":"10 mm","Forwards":"20 mm","Stranded":"70 ... 240 mm²","at 50 Hz":"0.4","at 60 Hz":"0.4","Downwards":"10 mm","Arcing Time":"10 ... 15 ms","At The Side":"10 mm","Rated Value":"200 ... 277 V","Initial Value":"0.8","During Storage":"-55 ... +80 °C","Of Magnet Coil":"Screw-type terminals","Number Of Holes":"1","at AC-1 maximum":"700 1/h","at AC-2 maximum":"200 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":"S12","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":"361 A","at 50 Hz rated value":"200 ... 277 V","at 500 V rated value":"2 A","at 60 Hz rated value":"200 ... 277 V","at 600 V rated value":"382 A","at 690 V rated value":"1 A","Side-By-Side Mounting":"Yes","at 1000 V rated value":"250 kW","For Auxiliary Contacts":"18 ... 14","Width Of Connection Bar":"25 mm","For Main Current Circuit":"Connection bar","at 200/208 V rated value":"125 hp","at 220/230 V rated value":"150 hp","at 460/480 V rated value":"300 hp","at 575/600 V rated value":"400 hp","Relative Humidity Minimum":"10 %","Of Main Circuit Rated Value":"8 kV","Thickness Of Connection Bar":"6 mm","at AC-3 rated value maximum":"1 000 V","at AC in hot operating state":"105 W","at AC-3e rated value maximum":"1 000 V","at AC-4 at 400 V rated value":"350 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":"378 A","at AC-5b up to 400 V rated value":"332 A","For Auxiliary And Control Circuit":"screw-type terminals","Function Module For Communication":"No","With Type Of Assignment 2 Required":"gG: 500 A (690 V, 100 kA), aM: 400 A (690 V, 50 kA), BS88: 450 A (415 V, 50 kA)","Without Load Current Share Typical":"3.6 W","closing power of magnet coil at DC":"800 W","holding power of magnet coil at DC":"3.6 W","At Contactor For Auxiliary Contacts":"Screw-type terminals","With Type Of Coordination 1 Required":"gG: 630 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":"35 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","voltage at PLC-control input rated value":"24 V","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":"6 600 A;
