Overview
The TCI KDRD22H is a three-phase KDR drive reactor engineered for output installation on variable frequency drives (VFDs). This TCI KDRD22H drive reactor protects AC motors and rectifier circuits by filtering voltage spikes and reducing harmonic distortion. The unit is rated for 208/240V systems and can handle continuous loads up to 47 amps at 15 horsepower. Its low-impedance design (0.05 impedance / 3% reactor classification) makes it suitable for general-purpose drive protection applications requiring moderate harmonic mitigation.
