The Siemens 4EU3652-0AW00-1BA0 is a 3-phase line reactor rated for 504 A continuous with a maximum current of 560 A at 50 Hz, 400 V AC. Inductance is 0.00011 H.
The 504 A rated current and 560 A maximum tell you this reactor is sized for a 400 V AC, 3-phase line feeding a drive or converter pulling up to 504 A continuous — with headroom to 560 A for short-duration overloads. The 0.00011 H inductance provides enough impedance to limit di/dt and reduce harmonic distortion on the line side. The flat-type terminals accept busbar or large cable lugs, not screw-clamp wire ends. Thermal class H per IEC 60085 means the insulation system withstands 180 °C hot-spot temperature, so it can run in a warm cabinet without derating as long as ambient stays at 40 °C. Dimensions: 0.35 m wide, 0.321 m tall, 0.227 m deep. That footprint matters for panel layout — it will not fit a shallow 200 mm enclosure depth. Plan for a cabinet at least 250 mm deep to allow air gap and cable bend radius below the flat terminals.
