High-current EMC/RFI Filter
3-Phase Filters FN3359
High-current EMC/RFI Filter
- Off-the-shelf high power filter for rated currents up to 2500 A
- HV versions applicable for IT power networks
- Busbars for convenient and universal electrical connection
- Protective plastic covers optionally available for unsurpassed safety
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
