Features and benefits
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
Performance indicators
The slim book-style shape allows a convenient and
space-saving installation next to inverters and
motor drives
With 480 VAC rating and filter modules from 7 to
250 A, FN 258 are ready for the most diverse
applications worldwide
FN 258 HV filters up to 130 A are designed for 690
VAC distribution networks
FN 258 HVIT filters up to 130 A meet the special
requirements for the application in industrial 690
VAC IT distribution networks
FN 258 L and FN 258 P 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
