Features and benefits
High-power filter for Class A compliance. With
approval measurement also Class B compliance
possible for some applications
Extremely compact high-current filter solution with
minimum space requirement
FN 3359 HV versions are applicable for IT power
networks
Optionally available transparent protective covers
for all filters up to 1000 A, to protect the installer,
operator or inspector from undeliberate touching of
life conductors. They can easily be retrofitted even if
the filter is already installed and connected
FN 3359 also improves conducted immunity of
installations
Typical applications
High-power motor drives, inverters and converters
Industrial three-phase systems
Entire factories, plants and installations
Large UPS
Machinery
Mining equipment
Photovoltaic systems with galvanic isolation*
Wind turbines
* For EMI solutions for PV system without galvanic
isolation, please contact your local Schaffner partner.
