=== Line Reactor === | |||
Automation Direct recommends an LR-2020 230 VAC 20 HP 3-phase 59.4 A 3% impedance line reactor ($195 as of January 2020). The LR-2020 has 0.172 mH of inductance. | |||
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. | |||
Alternatives: | |||
* MTE RL-04501 (45 A, 0.300 mH, 3-phase, 7.4" H x 4.7" W x 9" D) for $289.31 on Galco or far less on eBay. | |||
