Line reactors
The maximum line reactor size in front of the drive must not exceed the following values:
Model J
[kW]
2.2
4
5.5
7.5
11
Model K
P2
[kW]

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 J: If a short circuit occurs, the motor can be used on a mains supply delivering not more than 5000 RMS
symmetrical amperes, 600 V maximum.
Model K: Suitable for use on a circuit capable of delivering not more than 5000 rms symmetrical amperes, when
protected by RK1, J or T Class fuses, rated 600 V.
Fuses
Model J: Fuses used for motor protection must be rated for minimum 500 V. Motors up to and including 7.5 kW
(10 hp) require class K5 UL-listed fuses. Any UL-listed fuse can be used for motors of 11 kW (15 hp).
Model K: Fuses used for motor protection must be rated for minimum 600 V.
For fuse sizes, see the section on recommended size of fuses.
