At 500 V it handles 30 kW, and at 690 V it handles 11.4 kW — so it covers standard 400 V and 500 V three-phase motor circuits across a range of induction and wound-rotor machines. Depth is 130 mm — check gland-plate clearance if the panel is shallow. ## Terminal wiring and conductor sizing Accepts solid wire from 2x 0.5 mm² up to 2x 4 mm², and stranded wire from 2x 0.75 mm² up to 2x 25 mm². ## Switching performance and life Maximum switching rates: 1,000 ops/hr in AC-1 (resistive), 800 in AC-3 (standard motor starting), 400 in AC-2, and 300 in AC-4 (plugging/reversing). DC arcing time is 20 to 25 ms. ## DC switching capability For DC loads: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V, and 6 A at 230 V. The 230 V figure likely refers to AC-1 resistive duty. These DC ratings are modest — the contactor is primarily designed for AC motor switching, not high-current DC breaking.","metaTitle":"Siemens 3RT1036-1BQ40 SIRIUS Power Contactor, S2, 22 kW at 4","metaDescription":"Siemens SIRIUS 3RT1036-1BQ40 power contactor, size S2, 22 kW at 400 V AC-2, 41 A AC-4, 30 kW at 500 V, screw terminals, IP20 front, current production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Contactors"],"specifications":{"Depth":"130 mm","Solid":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²), max. 2x (0.75 ... 4 mm²)","Width":"55 mm","at DC":"20 ... 25 ms","Height":"112 mm","Stranded":"2x (0.75 ... 25 mm²)","Arcing Time":"10 ... 15 ms","Rated Value":"240 V","On The Front":"IP20","Initial Value":"0.8","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","Full-Scale Value":"1.1","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 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","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","closing power of magnet coil at DC":"13.3 W","holding power of magnet coil at DC":"13.3 W","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)","Type Of Voltage Of The Control Supply Voltage":"DC","Required Spacing For Grounded Parts At The Side":"6 mm","contact rating of auxiliary contacts according to UL":"A600 / Q600","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":"0","number of NO contacts for auxiliary contacts instantaneous contact":"0","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=377778&mlfb=3RT1036-1BQ40","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RT1036-1BQ40/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional alternative to 3RT1036-1BQ40?","answer":"The 3RT1044-1FB46 is a larger frame size (S3 vs S2) with higher ratings.
