Features and benefits
Typical applications
Mainly industrial equipment, machinery and
machine tools such as printing machines,
packaging machines, extruders, wood
working machines, milling and drilling
machines, laser cutting machines, welding
machines, robotics, conveyors, assembly
lines, pumps, oil production, chemical and
mining industry.
■ An extremely compact and light weight
filter design requiring minimum mounting
space in machinery and equipment.
■ 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, which is
very common for machine tools.
■ 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 help to ensure the com-
pliance with the new product family stan-
dard for machine tools in mainly industrial
environments EN 50370-1.
■ FN 3275 provides the attenuation perform-
ance to meet the requirements of various
machine tools with up to 8 driving axes
with ~10m of motor cable each.
■ The use of FN 3275 on the mains input will
also increase the immunity of the entire
installation.
