3-phase lters
FN 3270
Compact three-phase EMC/RFI lter
for industrial motor drive applications
Approvals
■
Very compact and light weight design
requiring minimum space
■
Easy, time-saving installation and
contacting
■
Protective covers as optional accessory
available
■
Attenuation performance according to
EN 61800-3/A11
Typical applications
■
An extremely compact and light weight
filter design requiring minimum mounting
space in installations and cabinets.
■
Simple and time-saving installation with
good accessibility for automatic and hand
tools.
■
Solid, touch-safe terminal blocks, for all
filters from 10 to 100A, offering sufficient
contacting cross section according to the
EN 60204-1 installation standard.
■
Optionally available transparent protective
covers for all filters with busbars from 150
to 1000A, to protect the installer, operator
or inspector from undeliberate touching of
life conductors. They can easily be retro-
fitted even if the filter is already installed
and connected.
■
These EMC filters provide the attenuation
performance needed to fulfill
EN 61800-3/A11.
■
Guaranteed filter performance under full-
load operating conditions.
■
15 different filter models allow the specific
choice and deployment for most industrial
applications.
■
Variable speed electrical power drive
systems/motor drives for mainly industrial
purpose
■
Various industrial applications comprising
frequency inverters, motor drives and
servo drives
