The Siemens 4EU3652-2UB00-1BA0 is a three-phase mains choke (line reactor) designed for use with frequency converters. It handles a maximum current of 1 000 A and a rated continuous current of 900 A at 500 V AC, with a rated inductance of 0.000018 H (18 µH). Rated for 50/60 Hz operation, the choke is built to thermal class H (180 °C insulation system per IEC 60085), with a total power loss of 460 W (310 W in the coil plus 150 W in the iron core) at the 40 °C ambient rating. The IP00 enclosure means it's an open-frame component intended for installation inside a panel or cabinet — not for standalone outdoor or washdown use.
The 4EU3652-2UB00-1BA0 carries a mature lifecycle stage — it remains available through independent distribution channels, not a current-production factory order. No official successor order code is listed, so for a BOM line this remains the direct fit.
The choke measures 0.35 m wide by 0.321 m tall by 0.237 m deep. Main circuit connections are via flat-type terminals — expect busbar or large cable lugs. The IP00 frame requires mounting inside a ventilated enclosure with clearance for heat dissipation; the 460 W total loss at full load means forced airflow or generous cabinet sizing is advisable.
