It carries a rated current of 90 A with a 100 A maximum at 400 V AC, 50 Hz, with an inductance of 0.28 mH and a relative inductive voltage drop of 4%. The 120 W coil loss and 39 W iron core loss are dissipated at a 40 °C ambient, and the thermal class H insulation (IEC 60085) gives it a 180 °C continuous winding temperature capability — important for sustained converter duty in a closed panel. Connections are via flat-type terminals (busbar or cable lug), common for high-current choke wiring in drive systems.
The 90 A rated current (100 A max) at 400 V AC, 50 Hz matches the line-side current of a converter in the 55–75 kW range, depending on the drive topology and overload profile. The 0.28 mH inductance and 4 % voltage drop are sized to limit the rate of rise of fault current and reduce harmonic distortion on the supply — a typical value for a commutating reactor in a 6-pulse rectifier front-end. The 50 Hz operating frequency is fixed; if your site runs 60 Hz, the choke will still function but the core losses and saturation margin shift — verify with the drive manufacturer's line reactor sizing guide.
