Siemens 4EU2722-7AA00-0AA0 Commutating Choke, 180A, 500V AC

It smooths current commutation and limits di/dt on the AC line feeding a variable-frequency drive or DC drive. Rated for 180 A continuous (200 A maximum) at 500 V AC, 50/60 Hz, with 0.18 mH inductance and a 4% relative inductive voltage drop at rated conditions. The IP00 open-frame construction means it mounts inside a cabinet — no enclosure of its own. Terminals are flat-type connectors, so busbar or lug connections are expected. Thermal class H (180 °C insulation system) gives it headroom in warm cabinets; the 40 °C ambient rating is the design point, but class H allows derating at higher temperatures without immediate failure. Copper loss is 160 W, iron loss 105 W — total 265 W dissipated as heat. That matters for cabinet cooling: a 265 W continuous heat source needs airflow or a fan in a sealed enclosure. The 0.248 m height, 0.27 m width, and 0.187 m depth footprint fits a standard 19-inch rack or panel floor, but verify busbar clearance above the flat terminals.
