This line choke is an option for variable speed drives of the Altivar range. Its nominal current is equal to 60A. It provides improved protection against overvoltages on the mains supply and helps reduce the harmonic distortion of the current generated by the inverter. Its degree of protection is IP00. It has an inductance value of 0.5 mH. It weighs 11 kg and has the following dimensions: 180 mm wide, 210 mm high, 165 mm deep. Its use is particularly recommended in cases of close parallel connection of several inverters, in cases of mains supply with significant disturbances from other equipment (interference, overvoltages). As well as in cases of mains supply with voltage imbalance between the phases.
