This motor choke is an option for Altivar 61 / Altivar 71 series variable speed drives. Its nominal current is equal to 12A. It is used as an output filter (between the drive output and the motor) and allows your drive to operate with motor cables longer than the maximum permitted lengths. Its protection degree is IP00. It weighs 5.5 kg. It is used to limit overvoltages at the motor terminals, filter interference and reduce the motor's earth fault current.
