Line reactors type ND17
Line reactors type ND401 to ND413 (u
k
= 4 %)
Line reactors of types ND401 to ND413 are sized to the unit‘s nominal current and frequency (50 /
60 Hz). These line reactors with a u
k
of 4 % are designed for use in light industrial / residential
environment. They have high inductive voltage drop, but reduced commutation notches. These line
reactors are designed for drives, which usually operate in speed control mode with 400 or 500 V
AC
mains. Thus the load cycle has to be taken into account. The percentage which is taken into account
for that duty cycle is different depending on the mains.
– for U

DC2
= 72 % of nominal current
Line reactors ND401 to ND402 are equipped with terminals. The larger ones ND403 to ND413 are
equipped with busbars. When connecting them to other components, please consider relevant
standards in case the busbar materials are different.
Attention:
Do not use the line reactor terminals as cable or busbar support!
