Its 0.18 mH inductance limits current rise during converter switching events, protecting the rectifier diodes and smoothing the DC bus ripple. The 160 A maximum continuous rating and 144 A nominal rating tell you the sustained load it can carry at 40 °C ambient — size your motor drive or converter load against the 144 A figure, not the peak. The 4% relative inductive voltage drop (uk) at rated current and frequency is the impedance you need for coordination studies — it determines how much voltage sag the choke introduces under load and how it contributes to fault current limiting. ## Thermal and Mounting Reality — IP00 Means Open Frame IP00 protection class means this choke has no enclosure — it's an open-frame component for mounting inside a panel or cabinet. The 131 W coil loss plus 64 W iron core loss (195 W total at rated conditions) must be ventilated out of the enclosure; don't bury it in a sealed box without forced airflow. Thermal class H insulation (180 °C hot-spot rating per IEC 60085) gives headroom for high-ambient environments, but the 40 °C ambient rating is the design point for the 144 A figure — derate above that.","metaTitle":"Siemens 4EU2522-2AA00-0AA0 Commutating Choke, 160A, 400V, 0.","metaDescription":"Siemens 4EU2522-2AA00-0AA0 commutating choke for converter applications. 3-phase, 400V AC, 160A max, 144A rated, 0.18mH, IP00, thermal class H.
