Line reactors are often required for six-pulse variable speed drives. Please observe that the MGE,
MLE utilize a small DC capacitor concept for lower harmonics and exceeding the maximum
inductance may cause resonance between reactor and the MGE, MLE that will reduce the lifetime of
the product.
Short-circuit current
Model K: Suitable for use on a circuit capable of delivering not more than 5000 rms symmetrical amperes, 480
V maximum when protected by RK1, J or T Class fuses, rated 600 V.
Fuses
Fuses used for motor protection must be rated for minimum 600 V.
