KDRI24L

TCI KDR series line reactors give you the best protection for both your drive and your applications!

There are two versions available, the Low 'Z' (low impedance - 1.5% or 3%) and High 'Z' (high impedance - 5%), you can find more information below.

Please note: input impedance can significantly improve drive performance, please select impedance based on the guidelines shown below.

Our KDR line reactors offer impedance against the flow of harmonics and other high frequencies that can cause tripping and equipment failure. Variable frequency drives, and other sensitive devices, are protected by the KDR series from electrical distortion on the line (including harmonics).

KDR line reactors can extend the life of the motor on the output of the VFD, protect equipment on the line, dramatically increase drive uptime by reducing tripping, improve power factor and reduce motor heating and noise.

Why would I use a KDR Low 'Z' unit?

Any application where either a 1.5% or 3% reactor would be applied.

Reduction of nuisance tripping caused by:

• Transient voltages caused by capacitor switching
• Line notching
• DC bus overvoltage tripping
• Inverter overcurrent and overvoltage

Why would I use a KDR High 'Z' unit?

Any application where a 5% reactor would be applied.

The High 'Z' offers all of the benefits shown on the Low 'Z' above plus:

• Helping prevent drive component damage
• Providing maximum harmonic mitigation without adding capacitiance

TCI line reactors are made right in Wisconsin! They are backed by a lifetime warranty which is the life of the drive.

Marshall Wolf Automation is your authorized TCI distributor!

July 2023: Please note the terminal hole size has been increased from 0.28 inches to 0.38 inches on all KDRI2H reactors (open and closed). The available lug kit, SLK10, will stay the same. This includes KDRI2H, KDRIH2C4, KDRI2HE01, KDRI2HE3R.
