Rated at 450 A with an inductance of 0.06 mH, it sits between the mains supply and the drive to smooth the current waveform and limit harmonic distortion. The 5% maximum voltage drop at rated load tells you the impedance is sized for effective filtering without robbing the drive of too much voltage headroom.
The 450 A rated current is the continuous RMS current the choke can carry under nominal conditions. The saturation current of 574 A is the point where the core starts to saturate and inductance drops off — the choke can handle 1.65 times nominal current for 60 seconds, which covers motor starting inrush and short overload events. Thermal losses of 335 W must be dissipated into the enclosure; at IP00, the choke is open-frame and relies on the panel's internal airflow, so factor that heat into your cabinet cooling budget.
The choke measures 320 mm wide by 385 mm high by 250 mm deep. It is rated for operation from 0 to 45 °C without derating; above that, derate 2% per °C up to 55 °C. Altitude derating starts at 1000 m — 1% per 100 m above that. Pollution degree 2 per EN 50178 means it is suited for a typical industrial control panel with non-conductive contamination. Vibration resistance is 1 gn from 13 to 200 Hz, and shock resistance is 15 gn for 11 ms — both per IEC 60068-2-6 and 60068-2-27 respectively, so it holds up in standard industrial environments.
The VW3A4569 is obsolete per the manufacturer.
