Rated operational current is 10 A at 24 V, but the real motor-switching number is the AC-3 rating: 3.5 kW at 500 V and 4 kW at 690 V. That's the figure that tells you whether this contactor handles your 5.5 HP motor at 480 V — it does, with headroom. For resistive loads (AC-1), the maximum operating current is 10 A. The coil pulls 1.4 W to close and holds at 1.4 W DC — that's a low continuous drain for a PLC output or a 24 VDC power supply. The integrated diode means you don't need an external flyback diode across the coil, but verify polarity: reverse voltage kills the diode and the coil driver. Spring-loaded terminals accept 2x (0.25 to 2.5 mm²) solid or stranded, or 2x (24 to 14 AWG). Strip length is standard for spring clamps — about 8 to 10 mm. No screwdriver needed for the power connections, which saves time on repetitive wiring. For Type 2 coordination (contactor remains fully functional after a fault), use a 20 A gL/gG fuse. That's the spec for sizing your branch circuit protection. The 3RT1015-2VB42 is a specific variant: S00 frame, 24 VDC coil with diode, spring terminals. If your panel was built around a screw-terminal version (like the 3RT1015-1BB42), the spring-terminal variant drops into the same footprint and same DIN rail slot — just different wiring method. If your existing panel uses a 3RT1016-2AP02 (larger frame or different coil voltage), the physical size and terminal layout differ; verify the mounting hole pattern and coil voltage before swapping.","metaTitle":"Siemens 3RT1015-2VB42 SIRIUS Power Contactor, S00, 24 VDC Co","metaDescription":"Siemens SIRIUS 3RT1015-2VB42 power contactor, size S00, 24 VDC coil with diode suppression, spring-loaded terminals, 10 A at 24 V, 4 kW at 690 V, current production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":null,"categoryPath":["Contactors"],"specifications":{"Depth":"73 mm","Solid":"2x (0.25 ... 2.5 mm²)","Width":"45 mm","Height":"60 mm","Maximum":"2 000 m","At The Side":"6 mm","Rated Value":"24 V","On The Front":"IP20","Initial Value":"0.85","Mounting type":"screw and snap-on mounting onto 35 mm standard mounting rail according to DIN EN 50022","Of The Terminal":"IP20","lifecycle_stage":"current","During Operation":"-25 ... +60 °C","Full-scale value":"1.85","Size of contactor":"S00","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":"3.5 kW","at 690 V rated value":"4 kW","Instantaneous Contact":"0","Side-by-side mounting":"Yes","For Main Current Circuit":"spring-loaded terminals","Single Or Multi-Stranded":"2x (0,25 ... 2,5 mm²)","at AC-2 at 400 V rated value":"3 kW","at AC-4 at 400 V rated value":"6.5 A","Design of the surge suppressor":"with diode","Closing power of magnet coil at DC":"1.4 W","Holding power of magnet coil at DC":"1.4 W","Operating current at AC-12 maximum":"10 A","With Type Of Assignment 2 Required":"fuse gL/gG: 20 A","at AWG conductors for main contacts":"2x (24 ... 14)","With Type Of Coordination 1 Required":"fuse gL/gG: 35 A","Reference code acc. to DIN EN 81346-2":"Q","Number of NC contacts for main contacts":"0","Number of NO contacts for main contacts":"3","Finely Stranded With Core End Processing":"2x (0.25 ... 1.5 mm²)","Number of poles for main current circuit":"3","at AWG conductors for auxiliary contacts":"2x (24 ... 14)","Contact reliability of auxiliary contacts":"1 faulty switching per 100 million (17 V, 1 mA)","For Auxiliary And Control Current Circuit":"spring-loaded terminals","at ambient temperature 40 °C rated value":"18 A","Finely Stranded Without Core End Processing":"2x (0.25 ... 2.5 mm²)","Type of voltage of the control supply voltage":"DC","For Short-Circuit Protection Of The Auxiliary Switch Required":"fuse gL/gG: 10 A"}},"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=92385&mlfb=3RT1015-2VB42","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RT1015-2VB42/alternatives.json"},"ai":{"faq":[{"question":"What are the key ratings I need to verify for fit?","answer":"The AC-3 motor switching power is 4 kW at 690 V and 3.5 kW at 500 V.
