Line Reactors for VFD
(Variable Frequency Drives)
- Line reactors used on the input side of a drive protect the AC drive from transient overvoltage conditions typically
caused by utility capacitor switching. Input line reactors also reduce
the harmonics associated with AC drives, and are recommended for all
installations.
- Line reactors used on the output side of a drive (load
reactors) protect the motor insulation against AC drive short
circuits and IGBT reflective wave damage, and also allow the motor to
run cooler by "smoothing" the motor current waveform. Output reactors
are recommended for operating "non-inverter-duty" motors and for any
motors when the length of wiring between the AC drive and motor exceeds
75 feet.

New!
- There are two series of AutomationDirect line reactors that can be
used with GS series AC Drives: the original GS series reactors (legacy)
and the newer LR series line reactors. New applications should use the
LR series of line reactors for cost savings. NOTE: LR-Series line
reactors can also be used with a variety of other VFD
brands.
- LR series reactors have universal mounting feet with multiple
mounting slots, and they can replace most reactors using the existing
mounting holes. Use four bolts to mount the reactors to the mounting
panel. LR series line reactors can be used on the input or output side
of any manufacturer's AC drive.
