FU, 3-phase mains choke, 500 V AC, 140 A max / 126 A rated, 0.13 mH, IP00, UL/CSA recognized, order code 4EU2452-1UA00-0AA0.","salesMarkdown":"FU\" tells you exactly that. It sits between the supply and the drive's rectifier, smoothing current harmonics and limiting inrush. This is an open-frame (IP00) component — no enclosure, no finger-safe terminals. It mounts inside a panel, not on a wall. The flat-type terminals for the main circuit are sized for lug or bus-bar connections, so plan for a bolted interface rather than a spring-cage or screw-clamp. Thermal class H insulation (180 °C) per IEC 60085 means the coil can run hot without degrading the magnet wire — that matters when the choke is pulling full current inside a warm cabinet. ## Power loss and thermal budget Total power loss splits into 125 W from the coil (copper losses) and 27 W from the iron core (hysteresis and eddy-current losses), for a combined 152 W at rated load. At 40 °C ambient, the choke is at its rated thermal capacity — push the cabinet temperature higher and you'll need to derate current or add forced airflow. ## Dimensions for panel layout Footprint is 0.225 m wide by 0.21 m tall, with a depth of 0.147 m. That's a substantial block — roughly 9 by 8 by 6 inches — so it needs dedicated real estate on the backplate or a mounting shelf. Not a DIN-rail snap-on; it bolts down.","metaTitle":"Siemens 4EU2452-1UA00-0AA0 Mains Choke for VFD, 140 A, 0.13","metaDescription":"Siemens 4EU2452-1UA00-0AA0 mains choke for VFD. 3-phase, 500 V AC, 140 A max, 0.13 mH, IP00.
