Its job is to limit current rise during commutation, reduce harmonic distortion, and provide a degree of line impedance that protects the converter's input diodes and DC bus capacitors. Rated at 504 A continuous (560 A maximum) at 500 V AC, 50 Hz, with an inductance of 65 µH, it's sized for a substantial drive — think 250–350 kW class, depending on the drive topology and duty cycle.
The 504 A rated current is continuous at 40 °C ambient. The 560 A maximum is the short-time thermal peak.
Width 0.35 m, height 0.321 m, depth 0.227 m. It is an open-frame IP00 component for enclosure mounting with flat-type bus-bar terminals.
