Rated for a maximum continuous current of 315 A and a rated operating current of 283.5 A at 690 V AC, 50 Hz, it's sized for a heavy industrial drive feeding a large motor load — think conveyor drives, pump stations, or compressor trains on a 690 V line. That 2 % drop is typical for a drive-input reactor — enough to clean up harmonics without robbing the drive of usable voltage. The inductance is 0.00008 H (80 µH), and total power loss from both the coil (220 W) and iron core (102 W) adds up to about 322 W of heat that must be dissipated into the surrounding air. ## Mounting and environment — what IP00 means in practice This is an IP00 open-frame component — no enclosure, no finger-safe cover. It must be installed inside a locked electrical cabinet or a restricted-access area where only qualified personnel can reach it. The thermal class is H (180 °C winding temperature per IEC 60085), which means the choke can run hot; the 40 °C ambient temperature rating is the baseline, and above that you derate per the manufacturer's curve. Dimensions are 0.300 m wide × 0.269 m high × 0.221 m deep — about the size of a small shoebox, but heavy enough that the mounting bracket needs solid support. Main current connections are flat-type terminals, so expect busbar or heavy cable lugs, not spring cages.","metaTitle":"Siemens 4EU3052-3UA00-0AA0 Mains Choke, 315A, 690V AC, IP00","metaDescription":"Siemens 4EU3052-3UA00-0AA0 mains choke for VFDs. 3-phase, 315A max, 690V AC, 50Hz, 2% voltage drop.
