Approvals & Compliances

Features and benefits

An extremely compact and light weight filter design

with a „cubic“ shape, requiring minimum mounting

space and thus taking the constructional conditions

on the mains input of machinery into account

Simple and time-saving installation with good

accessibility for automatic and hand tools

Solid, touch-safe terminal blocks offering sufficient

contacting cross section according to the EN

60204-1 installation standard, which is very

common in industrial applications

As a mains input filter for three phases and neutral

line, FN 3256 ensures the compliance with the new

product family standard for machine tools in mainly

industrial environments EN 50370-1. Further, its use

will also increase the conducted immunity of the

entire installation significantly

FN 3256 provides the attenuation performance to

meet the requirements of various machine tools

with up to 8 driving axes with ~10 m of motor cable

each

For easy selection and application, the filter current

ratings are aligned with common fuse values

Typical applications

Mainly industrial equipment, machinery, machine

tools and diverse process auto- mation systems with

three-phase and neutral electricity supply. Further,

these filters are suitable for power supplies, high-

power office equipment and further applications,

where efficient interference suppression on three

phases and the neutral line is required and where

space is critical. Because of the very low leakage

current, FN 3256 can even be used for some medical

devices.
