The Siemens 4EU2722-0FE00-0BA0 is a 3-phase commutating choke (line reactor) for converter applications, rated 163 A continuous with a 180 A maximum, at 480 V AC, 50/60 Hz. Its 0.16 mH inductance and 4 % relative inductive voltage drop smooth the current waveform and limit di/dt on the converter's input, reducing harmonic distortion and protecting the DC bus capacitors from switching transients. Rated for a 50 °C ambient with thermal class H insulation, this choke is built for sustained operation in a warm cabinet without derating.
IP00 means the choke has no enclosure — it mounts inside a panel or drive cubicle, with the main circuit connections via flat-type terminals (bus-bar or cable lug). Footprint is 0.27 m wide by 0.248 m tall by 0.208 m deep; plan for clearance around the flat terminals and for airflow over the core.
