Product Overview
Allen-Bradley reactors help keep equipment running longer by absorbing many of the power line disturbances which can shut down your drive. Allen-Bradley isolation transformers can provide both voltage change and isolation for your variable speed drive. The designs are harmonic compensated and IGBT protected to assure optimum performance in the prence of harmonics.

Applying Allen-Bradley Line Reactors At the Input of the Drive
cipherAt the input of a drive, line reactors help protect against surges or spikes on the incoming power lines and help reduce harmonic distortion.At the Output of the Drive
In long motor lead applications, Allen-Bradley load reactors located between the drive and motor help reduce dv/dt and motor terminal peak voltages. The u of a load reactor also helps protect the drive from surge currents caud by rapid changes in the load.
With Multiple Drives
Multiple drives on a common power line should each have their own line reactor. Individual line reactors provide filtering between each drive to help reduce any crosstalk while providing optimum surge protection for each drive.
With Multiple Motors
When more than one motor is controlled by a single drive, a single line reactor can typically be ud between the drive and all the motors. Size the line reactor bad on the total motor/load horpower.
uma
With Single-Pha Input
A three-pha reactor can be ud for single-pha applications by routing each of the two input power conductors to the outside two coils, and leaving the center coil disconnected. The sum of the inductance of the two coils is the total inductance applied to the circuit. Contact Rockwell Automation

Selecting the Correct Impedance Rating
Why is the Right Impedance Rating Important?
Selecting the correct impedance rating is critical for your job. An impedance value too low may not limit peak current. T oo high of an impedance may reduce input voltage. Allen-Bradley line reactors offer two impedance ratings.
3% Impedance Rated Reactors to Reduce Nuisance Trips
Allen-Bradley line reactors rated at 3% are typically sufficient to absorb line spikes and motor current surges and will help prevent nuisance tripping of drive and circuit breakers in most applications.
5% Impedance Rated Reactors to Reduce Harmonic Contentcutdown
Allen-Bradley reactors rated at 5% are best for reducing harmonic current and frequencies. The line reactors help comply with IEEE-519 (not normally ud as load reactors).
Voltage Spike Protection
Voltage spikes on AC power lines can cau elevation of the DC bus voltage which may cau the drive to trip on an overvoltage condition.
3% impedance reactors are very effective at protecting drives against voltage spikes and nuisance tr
ipping. Allen-Bradley line reactors absorb the line spikes protecting the drive from nuisance tripping and damage.
Motor Protection
Allen-Bradley load reactors can help protect motors from high peak voltages.
For IGBT drive applications with long drive-to-motor lead lengths, Allen-Bradley load reactors can help protect against fast dv/dt ri times.
