Filters of the NFK855-31 series are used to suppress circuit-bound interferences in three-phase AC power lines without neutral conductor.
Interference pulses or interference voltages are dampened independently from their point of origin.
The filters are built with 1 stage and have a high insertion loss on a wide frequency range.
  • High insertion loss over a broad frequency range
  • Optimised against asymmetric interferences
  • compact enclosure design
  • Using aluminium enclosure in order to improve the heat conduction
  • Suitable for the tropics - epoxy resin casted
  • Safety acc. to VDE, EN, UL, CSA
