Coil is 48 VDC, screw-type terminals on both coil and main contacts. Integrated auxiliary switch (1 NO + 1 NC) is wired to the same terminal block, saving a separate aux block on the DIN rail. Dimensions: 45 mm wide, 58 mm tall, 73 mm deep — fits standard S00 cutout in a 40 mm deep enclosure with clearance for wiring. For doubled conductors: 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), or 2x 4 mm². Strip length follows standard screw-terminal practice — no special tooling required. Main contacts are 3-pole (3 NO), rated for 20 A at 400 V AC-3e. Rated for 1,000 operations per hour at AC-1 (resistive), 750 ops/h at AC-2 and AC-3 (motor), and 250 ops/h at AC-4 (plugging/inching). Switching times: DC coil pickup 7...13 ms, arcing time 10...15 ms.","metaTitle":"Siemens 3RT2016-1BW42 SIRIUS Power Contactor, S00, 48 VDC Co","metaDescription":"Siemens 3RT2016-1BW42 SIRIUS power contactor, size S00, 48 VDC coil, screw terminals, 3-pole main contacts, auxiliary switch, 35 mm DIN rail mount, current production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Contactors"],"specifications":{"Depth":"73 mm","Solid":"0.5 ... 4 mm²","Width":"45 mm","at DC":"7 ... 13 ms","Height":"58 mm","Upwards":"10 mm","Forwards":"10 mm","Stranded":"0.5 ... 4 mm²","Downwards":"10 mm","Arcing Time":"10 ... 15 ms","At The Side":"6 mm","Rated Value":"48 V","Initial Value":"0.8","During Storage":"-55 ... +80 °C","Of Magnet Coil":"Screw-type terminals","at AC-1 maximum":"1 000 1/h","at AC-2 maximum":"750 1/h","at AC-3 maximum":"750 1/h","at AC-4 maximum":"250 1/h","lifecycle_stage":"current","Auxiliary Switch":"Yes","During Operation":"-25 ... +60 °C","Fastening Method":"screw and snap-on mounting onto 35 mm DIN rail according to DIN EN 60715","Full-Scale Value":"1.1","at AC-3e maximum":"750 1/h","For Main Contacts":"20 ... 12","Mounting Position":"+/-180° rotation possible on vertical mounting surface;
