The 0.18mH inductance and 4% relative inductive voltage drop smooth out line harmonics and limit inrush current, protecting the drive's rectifier stage from voltage spikes and reducing total harmonic distortion on the line side. ## Sizing and thermal reality The 180A rated current is the continuous duty figure at 40°C ambient with Class H insulation (180°C rated temperature rise per IEC 60085). The total power loss breaks down to 220W in the coil and 87W in the iron core — 307W total that has to leave the enclosure. At IP00 there's no housing; this choke sheds heat directly into the cabinet air. In a sealed panel, that heat load needs to be factored into the cooling budget. The 200A maximum rating is the short-term overload ceiling, not a continuous operating point. This is a panel-mount component — no DIN rail clip. Dimensions are 0.3m wide by 0.269m tall by 0.221m deep. The main circuit connection uses flat-type terminals, so you'll need ring or fork lugs sized for the cable that carries 180A continuous. The IP00 rating means it's open-frame; install it where no accidental contact can occur during operation, or provide supplementary guarding.","metaTitle":"Siemens 4EU3052-0UB00-0AA0 Mains Choke, 200A 500V AC 3-Phase","metaDescription":"Siemens 4EU3052-0UB00-0AA0 mains choke for variable frequency drives. 3-phase, 500V AC, 180A rated / 200A max, 0.18mH, IP00, UL/CSA recognized.
