The screw-type main terminals accept solid wire up to 2x 4 mm² or stranded up to 2x 25 mm², which covers common power wiring for this class. The AC-3 motor-switching rating of 30 kW at 500 V tells you this contactor can start and stop a standard squirrel-cage induction motor up to that power — the most common duty cycle for conveyor, pump, and fan loads. The AC-4 rating of 41 A at 400 V covers plugging and inching applications where the motor is reversed or jogged under load, which generates higher arcing stress. Maximum switching rates are 800 cycles per hour for AC-3 and 300 for AC-4, so it's not intended for high-speed cycling like a welding gun. The 48 VDC coil pulls in with a typical operating time of 20 to 25 ms and an arcing time of 10 to 15 ms. The coil is rated for continuous duty at 0.8 to 1.1 times the rated voltage, so it holds reliably down to about 38 V and up to 53 V. The S2 frame measures 95 mm wide, 112 mm high, and 130 mm deep — a compact footprint for a 30 kW contactor. It snaps onto standard 35 mm DIN rail per EN 50022, and the screw terminals accept solid wire from 0.5 to 4 mm² or stranded from 0.75 to 25 mm².","metaTitle":"Siemens SIRIUS 3RT1036-1DW48-0PA6 Power Contactor, 48 VDC Co","metaDescription":"Siemens SIRIUS 3RT1036-1DW48-0PA6 power contactor, 48 VDC coil, S2 frame, 30 kW at 500 V, screw terminals, IP20 front, active production, RoHS compliant.","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":"95 mm","at DC":"20 ... 25 ms","Height":"112 mm","Stranded":"2x (0.75 ... 25 mm²)","Arcing Time":"10 ... 15 ms","Rated Value":"48 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","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","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":"2","number of NO contacts for auxiliary contacts instantaneous contact":"1","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=83600&mlfb=3RT1036-1DW48-0PA6","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RT1036-1DW48-0PA6/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional second-source to this contactor?","answer":"The closest functional second-source within the same SIRIUS family is the 3RT1036-1AB00, which shares the same S2 frame size and screw-type terminals.

They are not drop-in interchangeable if your control circuit is 24 V, but they share the same mechanical footprint and main current ratings."},{"question":"What wire sizes does the screw terminal accept?","answer":"The screw-type main terminals accept solid wire: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), max 2x (0.75 to 4 mm²).
