Power capacitors multicond

multicond - Power capacitors for reactive current compensation

Power capacitors for reactive current compensation in single-phase and 3-phase versions, developed for the highest requirements. Apart from a long operating life and high current and voltageload capacity, safety in case of overload (all-pole overpressure disconnector) is a crucial advantage of the compact dry technology components. Other features are good heat dissipation, low self-heating as well as reliable performance at high ambient temperatures.

Highlights

  • Power from 2.8 to 37 kvar
  • Capacitor rated voltage of 280, 440, 480, 525, 690 or 800 V
  • High level of safety through dry technology and 3-phase internal overpressure disconnector
  • Including compact discharge resistor
  • Long operating life
  • Made in Gemany
