It sits between the supply and the drive's rectifier, 3-phase AC, rated 500V at 50Hz. The 630A maximum current and 567A rated current tell you the continuous load it can carry without saturating the core. For a 500V supply, that's about 10V drop across the choke at full current. Total power loss is 440W — 310W in the coil plus 130W in the iron core — at 40°C ambient. That heat has to leave the cabinet; the IP00 open-frame rating means it's not sealed, so forced ventilation or a generously sized enclosure is expected. ## Sizing and fit — cabinet reality Physical footprint: 0.35m wide, 0.321m tall, 0.237m deep. That's a substantial block — roughly 350mm × 321mm × 237mm. It's not a DIN-rail component; it bolts into a panel or chassis, and the flat-type terminals accept busbar or lug connections, not spring-cage wire. Class H insulation (IEC 60085) means the winding can handle 180°C hot-spot temperature. That's the headroom that lets it run at 567A continuous in a 40°C ambient without cooking the magnet wire. For a line-side choke on a high-duty VFD, that thermal class is what keeps the MTBF acceptable.","metaTitle":"Siemens 4EU3651-2UA00-0A Mains Choke for VFD, 630A, 500V, 3-","metaDescription":"Siemens 4EU3651-2UA00-0A mains choke for VFD. 630A max, 567A rated, 500V AC, 3-phase, 50Hz.
