It limits current rise and harmonics on the line side of a variable-frequency drive or DC drive, protecting both the converter and the upstream supply. The 0.2 mH inductance and 4% relative inductive voltage drop are sized for typical drive input filtering.
The 126 A rated current (I LN) is the continuous thermal current at 40 °C ambient — this is the number to match against your drive's input current, not the 140 A maximum. The 140 A maximum (I thmax) is the short-time overload ceiling, not a continuous rating. Thermal class H insulation (180 °C) gives headroom for high-ambient cabinets or tight enclosures. The IP00 rating means no enclosure protection; the choke must be mounted inside a panel with proper clearance to live parts.
Integration notes
Dimensions are 0.225 m wide × 0.21 m high × 0.16 m deep — check your panel backplate for footprint clearance. The main circuit connection uses flat-type terminals (bus-bar style), not ring lugs or screw clamps; plan your bus-bar or cable-lug interface accordingly.
