Automation Direct recommends an LR-2015 (46.2 A, 0.22 mH, 3-phase, 4.25" H x 7.2" W x 4.75" D) for $179 on Automation Direct.
A 3% impedance reactor absorbs transients and prevents nuisance tripping of drives in most applications.  A 3% impedance line reactor 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.
Multiple alternatives to the LR-2015 have been evaluated:
* 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.
* TCI KDRD24L (208/240 VAC 48 A 15 HP, 3-phase, 3% - Low Z, 3.82" H x 6.95" W x 5.57" D).  $195.94 on Galco (eBay TBD).
* Hammond CRX0046AC (46 A, 0.21 mH, 15 HP, 3-phase, 3%, 5.00" L x 6.13" H x 4.38" D, 40 Watts).  Not readily available on eBay.
