The 0.000043 H inductance and 4% relative inductive voltage drop are sized to limit di/dt and smooth commutation notches on the converter's input — critical for protecting the DC link capacitors and reducing harmonic distortion on the line side.
At 910 A max and 819 A rated, this choke is sized for a 690 V AC drive system pulling around 900 A — think a large conveyor drive, a mine hoist, or a multi-motor pump station. The 1,138 A peak handles inrush during converter start-up without saturating the core. IP00 means it's an open-frame component: mount it inside a ventilated cabinet, not in a washdown area. The flat-type terminals accept busbar or large cable lugs — plan for a bolted connection, not a spring cage. Dimensions are 0.46 m wide, 0.435 m high, 0.265 m deep; that's a substantial footprint, so verify your gland plate and DIN rail clearance before committing the panel layout.
Thermal and loss budget
Total power loss is 728 W — 448 W in the coil and 280 W in the iron core. At 40 °C ambient, that's a lot of heat to evacuate. Thermal class H per IEC 60085 means the insulation system can handle 180 °C hot-spot temperature, so the choke won't cook itself, but your cabinet ventilation needs to move that 728 W out. Derate the ambient if your enclosure runs hotter than 40 °C — the class H rating gives headroom, but the copper losses scale with current squared.
