Line reactor types 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 reactors are designed for drives, which
usually operate in speed control in 400 or 500 V
AC
networks. The percentage taken into account for that duty
cycle is different:
−
for U
supply
= 400 V
AC
follows I
DC1
= 90 % of nominal current,
−
for U
supply
= 500 V
AC
follows I
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!
