This is the line reactor that sits between the drive's DC link and the inverter stage — it limits current rise during commutation, reduces harmonics, and protects the converter's semiconductor switches. Mounting is open-frame (IP00), so it goes inside a cabinet — not on the panel door or in a washdown zone. Dimensions: 0.270m wide × 0.248m high × 0.187m deep. Connections are flat-type terminals sized for the 315A current path; expect busbar or large-gauge cable lugs. Thermal class H (180°C) insulation per IEC 60085 means it can run hot in a sealed enclosure, but the 174W copper loss plus 75W iron loss (249W total at rated load) needs to be vented — don't bury it in a tight compartment without airflow.","metaTitle":"Siemens 4EU2722-8BA00-0AA0 Commutating Choke, 315A AC, 66µH","metaDescription":"3-phase 400V AC commutating choke for converter drives.
