The SIDAC 4EU3052-0EF00-1BA0 is a 3-phase AC output reactor rated for a maximum continuous current of 250A and a rated switching frequency of 8000Hz. This is the choke that sits between a variable-frequency drive output and the motor cable — it limits the rate of voltage rise (dV/dt) and reduces bearing currents on long cable runs. The 0.02 mH inductance and 8.36% impedance (UK) are sized for drives in the 225A continuous current class (I LN).
IP00 protection class means this reactor has no enclosure — it is intended for mounting inside a cabinet, not in a wet or dusty environment. Thermal class H insulation (rated for 180°C hot-spot) gives headroom in high-ambient panels, though the datasheet bases ratings at a 40°C ambient. Main circuit connections use flat-type terminals, so plan for busbar or compression lugs rather than ring terminals. Dimensions are 0.3m wide by 0.26m tall by 0.21m deep — account for that footprint plus clearance for airflow around the core.
