Its job is to limit harmonic distortion, reduce peak currents, and provide some protection against line transients upstream of the drive's DC bus. The 360 A rated current (with a 400 A maximum) at 690 V AC and 50 Hz tells you this is sized for a high-power drive — think large pumps, compressors, or conveyor systems in the 200–300 kW range on a 690 V supply. The IP00 protection class means this is an open-frame component — no enclosure. It mounts inside a panel or cabinet, not in a wet or dusty environment. The flat-type terminals accept busbar or large cable lugs; plan for a bolted connection, not a spring-cage or screw-clamp. The 220 W coil loss plus 102 W iron core loss (322 W total at rated load) must be ventilated out of the enclosure — that's real heat, roughly equivalent to a small space heater, so forced air or a generously sized cabinet is expected. ## Integration — what fits where Physical footprint: 0.3 m wide, 0.269 m tall, 0.221 m deep. That is a substantial block — roughly 12 by 11 by 9 inches. It is not a DIN-rail component; it bolts directly to a backplate or chassis. The flat-type terminals are the main current connection; verify your busbar or cable lug pattern matches the terminal spacing before committing the panel layout. The 322 W total heat dissipation means the surrounding components — especially upstream fusing and downstream drive — should not be thermally shadowed. Leave at least 100 mm clearance around the choke for airflow, more if other heat sources are nearby.","metaTitle":"Siemens 4EU3052-4UA00-0AA0 Line Reactor, 360A, 690V, 3-Phase","metaDescription":"Siemens 4EU3052-4UA00-0AA0 mains choke for VFD. 360A rated, 690V AC, 0.063 mH, 2% voltage drop.
