Filters of the NFK4135-30A42 series are used to suppress circuit-bound interferences in three-phase AC power lines with neutral conductor.
Interference pulses or interference voltages are dampened independently from their point of origin.
To improve the filter effect they are designed with 2 stages and have a high insertion loss on a wide frequency range.
- High insertion loss over a broad frequency range
- 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
