This line choke is an option for variable speed drives of Altivar range.Its rated current is equal to 4A.It provides improved protection against overvoltages on the line supply and contributes to reduce harmonic distortion of the current produced by the drive.Its protection index is IP00.It has an inductance value of 10mH.It weighs 1.5kg and its dimensions are, 100mm wide, 135mm high, 60mm deep.Its use is particularly recommended in case of close connection of several drives in parallel, line supply with significant disturbance from other equipment (interference, overvoltages), line supply with voltage imbalance between phases.
