For AC-4 (inching, plugging, jogging) it carries 8.5 A at 400 V. Type 1 coordination requires a 35 A gL/gG fuse; Type 2 coordination needs a 20 A gL/gG fuse. Main contacts accept 2x (0.5 to 1.5 mm²) solid, 2x (0.75 to 2.5 mm²) stranded, or up to 2x 4 mm² max. Auxiliary terminals match. AWG equivalents: 2x (20 to 16) solid, 2x (18 to 14) stranded, or 1x 12. Side-by-side mounting is supported without derating — zero gap between units on the rail. ## Sourcing note This is a standard fast mover in the SIRIUS line — keep it on the shelf if you maintain panels with 24 V DC control.","metaTitle":"Siemens 3RT1017-1VB42 SIRIUS Power Contactor, 24 V DC, Size","metaDescription":"Siemens 3RT1017-1VB42 SIRIUS power contactor, 24 V DC coil, Size S00, 5.5 kW at 400 V AC-2, screw terminals, IP20, current lifecycle, available to order.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Contactors"],"specifications":{"Depth":"72 mm","Solid":"2x (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²), max. 2x (0.75 ... 4 mm²)","Width":"45 mm","Height":"57.5 mm","Rated Value":"24 V","On The Front":"IP20","Initial Value":"0.85","Of The Terminal":"IP20","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":"1.85","Size Of Contactor":"S00","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","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":"30 000 000","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":"5.5 kW","at 690 V rated value":"5.5 kW","Side-By-Side Mounting":"Yes","For Main Current Circuit":"screw-type terminals","at AC-2 at 400 V rated value":"5.5 kW","at AC-4 at 400 V rated value":"8.5 A","Substance Prohibitance (Date)":"01.07.2006 00:00:00","Design Of The Surge Suppressor":"with diode","at AWG cables for main contacts":"2x (20 ... 16), 2x (18 ... 14), 1x 12","For Auxiliary And Control Circuit":"screw-type terminals","With Type Of Assignment 2 Required":"fuse gL/gG: 20 A","closing power of magnet coil at DC":"1.4 W","holding power of magnet coil at DC":"1.4 W","reference code acc. to IEC 81346-2":"Q","With Type Of Coordination 1 Required":"fuse gL/gG: 35 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","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)","Type Of Voltage Of The Control Supply Voltage":"DC","Required Spacing For Grounded Parts At The Side":"6 mm","Installation Altitude At Height Above Sea Level Maximum":"2 000 m","For Short-Circuit Protection Of The Auxiliary Switch Required":"fuse gL/gG: 10 A","number of NC contacts for auxiliary contacts instantaneous contact":"1","number of NO contacts for auxiliary contacts instantaneous contact":"0"}},"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=120110&mlfb=3RT1017-1VB42","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RT1017-1VB42/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional second-source for 3RT1017-1VB42?","answer":"The 3RT1016-1BB42 is a smaller-frame sibling (Size S0 vs S00) with a different coil voltage — it won't drop in without rewiring.
