Switching capacity covers a range of motor duties: at AC-3 (standard motor start/run) it handles 3.5 kW at 500 V and 4 kW at 690 V. For resistive loads (AC-1) the maximum operating current is 10 A at 24 V and 6 A at 230 V. The contactor is also rated for AC-4 (plugging/reversing) at 6.5 A at 400 V. Main power terminals are screw-type, accepting 2 x (0.5 to 1.5 mm²), 2 x (0.75 to 2.5 mm²), or up to 2 x (0.75 to 4 mm²) solid or stranded conductors. AWG equivalents are 2 x (20 to 16), 2 x (18 to 14), and 1 x 12. Short-circuit protection: with Type 1 coordination, use a gL/gG fuse rated up to 35 A. This matters when you're coordinating with upstream breakers in a motor control center. No special conformal coating required for typical panel use. The 24 VDC coil with diode suppression is a common variant, and the S00 frame is widely used in light industrial control.","metaTitle":"Siemens SIRIUS 3RT1015-1VB42 power contactor, 24 VDC coil, S","metaDescription":"Siemens SIRIUS 3RT1015-1VB42 power contactor, S00 frame, 24 VDC coil with diode suppression, screw terminals, IP20, active production.","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","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":"screw-type terminals","Single Or Multi-Stranded":"2x (0,5 ... 1,5 mm²), 2x (0,75 ... 2,5 mm²), max. 2x (0,75 ... 4 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 (20 ... 16), 2x (18 ... 14), 1x 12","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 (0.5 ... 1.5 mm²), 2x (0.75 ... 2.5 mm²)","Number of poles for main current circuit":"3","at AWG conductors for auxiliary contacts":"2x (20 ... 16), 2x (18 ... 14), 1x 12","Contact reliability of auxiliary contacts":"1 faulty switching per 100 million (17 V, 1 mA)","For Auxiliary And Control Current Circuit":"screw-type terminals","at ambient temperature 40 °C rated value":"18 A","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=333922&mlfb=3RT1015-1VB42","alternativesUrl":"https://aoctrl.com/api/mcp/products/3RT1015-1VB42/alternatives.json"},"ai":{"faq":[{"question":"What is the depth of this contactor?","answer":"The depth is 72 mm, measured from the mounting surface to the front of the device."},{"question":"What wire sizes does the screw terminal accept?","answer":"The main circuit screw terminals accept 2 x (0.5 to 1.5 mm²), 2 x (0.75 to 2.5 mm²), or up to 2 x (0.75 to 4 mm²) solid or stranded.
