The 690 V rating of 11.4 kW confirms it can handle higher-voltage distribution systems, though at reduced power. Auxiliary contact ratings cover 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V — enough for pilot duty on small relays or PLC inputs, but not for main power. The switching frequency limits of 800 cycles/hour in AC-3 and 300 cycles/hour in AC-4 set the thermal ceiling for repetitive switching; exceed these and the contactor rises above its rated temperature. The IP20 rating on the front protects against finger contact; the IP00 terminal area means the connection points are exposed and require enclosure protection in the panel. ## Mounting and Termination Side-by-side mounting is permitted, which lets you pack multiple contactors without dead space, but derating for thermal accumulation should be verified per the manufacturer's guidelines. The auxiliary terminals accept 2x 0.5 to 1.5 mm² solid or 2x 0.75 to 2.5 mm² stranded. This covers common panel wire sizes from 18 AWG to 4 AWG, but verify lug compatibility for larger stranded conductors. Shock resistance is 15 g for 5 ms and 8 g for 10 ms under AC operation, with DC operating time of 20 to 25 ms and arcing time of 10 to 15 ms. These figures matter for applications near heavy machinery or conveyors where vibration could cause contact bounce. Compliance documentation includes RoHS substance prohibition dated May 1, 2012, covering the initial EU RoHS directive. REACH, UL, and IEC certifications are standard for the SIRIUS family, though specific cert numbers should be verified against the nameplate or manufacturer's declaration.","metaTitle":"Siemens SIRIUS 3RT1036-1CP04-0KV0 Power Contactor, S2, 22 kW","metaDescription":"Siemens SIRIUS 3RT1036-1CP04-0KV0 power contactor, S2 frame, 22 kW AC-2 at 400 V, 41 A AC-4 at 400 V, 55 mm wide, screw terminals, DIN rail mount, current lifecycle stage.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Contactors"],"specifications":{"Depth":"164 mm","Solid":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²), max. 2x (0.75 ... 4 mm²)","Width":"55 mm","at AC":"15g / 5 ms, 8g / 10 ms","at DC":"20 ... 25 ms","Height":"112 mm","Stranded":"2x (0.75 ... 25 mm²)","at 50 Hz":"0.8 ... 1.1","Arcing Time":"10 ... 15 ms","On The Front":"IP20","1 Rated Value":"50 Hz","During Storage":"-55 ... +80 °C","Of The Terminal":"IP00","at AC-1 maximum":"1 000 1/h","at AC-2 maximum":"400 1/h","at AC-3 maximum":"800 1/h","at AC-4 maximum":"300 1/h","lifecycle_stage":"current","During Operation":"-25 ... +60 °C","Fastening Method":"screw and snap-on mounting onto 35 mm standard mounting rail according to DIN EN 50022","Size Of Contactor":"S2","Solid Or Stranded":"2x (0.75 ... 16 mm²)","Product Brand Name":"SIRIUS","Degree Of Pollution":"3","Product Designation":"power contactor","at 24 V rated value":"10 A","at 60 V rated value":"2 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":"230 V","at 500 V rated value":"30 kW","at 690 V rated value":"11.4 kW","Side-By-Side Mounting":"Yes","For Main Current Circuit":"screw-type terminals","at AC-2 at 400 V rated value":"22 kW","at AC-4 at 400 V rated value":"41 A","Substance Prohibitance (Date)":"05/01/2012","at 40 °C minimum permissible":"16 mm²","at 60 °C minimum permissible":"16 mm²","Design Of The Surge Suppressor":"with varistor","Insulation Voltage Rated Value":"690 V","at 230 V at 60 °C rated value":"22 kW","at 690 V at 60 °C rated value":"66 kW","at AWG cables for main contacts":"2x (18 ... 2)","For Auxiliary And Control Circuit":"screw-type terminals","With Type Of Assignment 2 Required":"fuse gL/gG: 80 A","Surge Voltage Resistance Rated Value":"6 kV","With Type Of Coordination 1 Required":"fuse gL/gG: 160 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","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)","Thermal Short-Time Current Limited To 10 S":"400 A","Finely Stranded Without Core End Processing":"2x (0.75 ... 16 mm²)","apparent holding power of magnet coil at AC":"12.5 VA","apparent pick-up power of magnet coil at AC":"145 VA","Type Of Voltage Of The Control Supply Voltage":"AC","Required Spacing For Grounded Parts At The Side":"6 mm","contact rating of auxiliary contacts according to UL":"A600 / Q600","Inductive Power Factor With Closing Power Of The Coil":"0.79","Installation Altitude At Height Above Sea Level Maximum":"2 000 m","Inductive Power Factor With The Holding Power Of The Coil":"0.36","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","Of The Contactor With Added Electronically Optimized Auxiliary Switch Block Typical":"5 000 000"}},"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=117880&mlfb=3RT1036-1CP04-0KV0","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RT1036-1CP04-0KV0/alternatives.json"},"ai":{"faq":[{"question":"What are the key dimensions for panel layout?","answer":"The contactor has a width of 55 mm, height of 112 mm, and depth of 164 mm.
