Technical Specifications

Characteristics elements Zvar® modular capacitor Enclosure Non-flamable and auto-extinguishing Poliamide in V0 flamability class Need to be grounded No - double insulation - class 2 Dielectric / Winding Polipropylen film, Alu-zinc metallized Impregnant Totally dry, cast resin technology Overpressure operating

(anti-explosion system) By operation of an overpressure device inside the enclosure

(flexible membrane, that disconnects normalized fuse link)) Capacitor and enviroment

hazard No risk because:

  • totally dry
  • external deformation does not appear
  • enclosure and resin are auto-extinguishing in V0 class

Ambient temperature class -40 do +55°C Permitted casing temperature 90°C Average temperature on 24h 45°C Watt losses (in heat) <0,3W / kvar (internal resistor included) Maximum admissible voltage

- according to standard IEC 60831-1 i 2 Ucn + 20% 24h/24h

Ucn + 25% 18h/24h

Ucn + 30% 12h/24h

Example Ucn = 440V + 20% = 528V 24h/24h - Permanent Maximum admissible current 1.5 ln Tested with voltage

(terminal to terminal) 2,15 Un AC 10sec. TTested with voltage

(terminal to enclosure) 6kV AC 1min

15kV AC 1,2/50μ sec. Statistical life expectancy >130 000h Mounting position Any position, because dry resin impregnan
