A 3% impedance reactor absorbs transients and prevents nuisance tripping of drives in most applications and is typical for the line side.  A 5% impedance reactor can be used if the harmonic content is severe or if IEEE519 recommendations should be met.  The reactor impedance magnitude is said to be equal to the voltage drop.

* Automation Direct recommends an LR-2015 (46.2 A, 0.22 mH, 3-phase, ) for $179 on Automation Direct.
* MTE RL-04501 (45 A, 0.300 mH, 3-phase, ) for $289.31 on Galco or far less on eBay.  This is a very large part.
* MTE RL-04501 (45 A, 0.300 mH, 3-phase, 4.60" H x 8.91" W x 7.13" D) for $289.31 on Galco or far less on eBay.  This is a very large part.
* MTE RLW-004601 (42 A, 3.68" H x 6.00" W x 5.76" D).  Not readily available.
