It carries a maximum current of 22.5 A and a rated current of 20.25 A at 400/480 V AC, 50/60 Hz, with an inductance of 0.63 mH and a relative inductive voltage drop of 2%. This 2% impedance is the standard value for drive input reactors — enough to smooth line notches and limit harmonic current without dropping excessive voltage under load.
The 22.5 A maximum and 20.25 A rated current tell you this choke is sized for a drive with a continuous input current around 20 A — typically a 7.5 kW to 11 kW drive on 400 V three-phase. The 2% voltage drop means the drive sees nearly full line voltage; a 4% choke would drop more voltage and reduce motor torque at the terminals, so this is the lighter filtering option. The 0.63 mH inductance at 50/60 Hz gives enough impedance to attenuate the 5th and 7th harmonics that cause DC-bus ripple and nuisance tripping on weak lines. IP00 means open-chassis — mounts inside a panel where ambient stays within 40 °C. Screw-type terminals accept standard power wiring. Thermal class B insulation handles continuous-duty coil temperatures.
