This line choke is an option for variable speed drives of the Altivar range. Its nominal current is equal to 10A. 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 4mH. It weighs 3 kg and has the following dimensions: 130 mm wide, 155 mm high, 90 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.
