FU), 3-phase AC, 400/480V, 100A max, 0.14mH, IP00, flat-type terminals.","salesMarkdown":"The Siemens 4EP4000-2US00 is a three-phase mains choke — Netzdrossel für Frequenzumrichter — sized for the input side of a variable-frequency drive. It sits between the supply and the drive's rectifier, smoothing line harmonics and limiting inrush current. Rated for 400/480 V AC at 50/60 Hz, it carries a maximum AC current of 100 A and a rated operational current of 90 A. Inductance is 0.00014 H (0.14 mH) with a 2% relative inductive voltage drop at rated conditions. The 73 W coil loss plus 30 W iron core loss (103 W total at rated conditions) needs to be cleared from the enclosure; IP00 means it is an open-frame component, so the panel's own airflow must handle the heat. The main circuit connects via flat-type terminals — expect busbar or crimp-lug terminations, not screw-clamp wire ports. Dimensions are 0.219 m wide by 0.179 m tall by 0.143 m deep. It is an open-chassis unit (IP00), so it mounts inside a cabinet, not on a panel surface. Thermal class B per IEC 60085 means the insulation system is rated for a 130 °C maximum hot-spot temperature, which aligns with the 40 °C ambient rating. ## Production status and sourcing That means it is still a standard catalog line item from Siemens — no last-time-buy window, no forced migration to a successor.","metaTitle":"Siemens 4EP4000-2US00 Mains Choke, 3-Phase 100A AC, IP00","metaDescription":"Siemens 4EP4000-2US00 mains choke for frequency converters. 3-phase, 400/480V AC, 100A max, 0.14mH, IP00.
