Book-style EMC/RFI fi lter for three-phase
inverters and power drive systems
FN 258 range of filters provides state-of-
the-art EMI attenuation based on an
innovative multi-stage filter topology.
They help to ensure compliance with
Class A or even Class B limits.
The slim book-style shape allows a
convenient and space-saving installation
next to inverters and motor drives.
With 480VAC rating and filter modules
from 7 to 250A, FN 258 are ready for the
most diverse applications worldwide.
FN 258HV filters up to 130A are designed
for 690VAC distribution networks.

Industry standard EMC solution for
three-phase PDS filtering
Slim space-saving book-style housing
Solid safety connector blocks or optional
wire output connections
Excellent attenuation performance
HV versions for up to 690VAC
HVIT versions for IT distribution networks
P/L versions with low leakage current
FN 258HVIT filters up to 130A meet the
special requirements for the application in
industrial 690VAC IT distribution
networks.
FN 258L and FN 258P filters help to fulfill
tough requirements in respect of leakage
current limitation and provide an excellent
solution to overcome problems with
nuisance tripping of sensitive earth
leakage detectors.
