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

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

Typical applications

Three-phase variable speed drives and power drive

systems (PDS)

IT power distribution networks (FN 258 HVIT)

Applications comprising energy conversion devices

(inverters, converters)

Process automation equipment

Three-phase power supplies and UPS

Applications with low-leakage current requirements

(FN 258 L and FN 258 P)
