Capacitor block 4ELFKBV.

Capacitor block is designed for filtering of higher harmonics up to 20 kHz, which arise using three-phase power supply bloks with external high frequency choke (works with frequencies over 2-8 kHz )

 N and PE separation enables the usage in connection with current protector at systems with five-wire power, also in cases where the capacity connected to ground. Details see in pdf
