Power capacitors

multicond

Reactive power compensation components

The multicond power capacitors have been developed for reactive current compensation in 1-phase and 3-phase versions – specifically for the highest demands on safety and service life.

In addition to long life expectancy and high current and voltage carrying capacity, safety in the event of overload thanks to the all-pole overpressure cut-out is a decisive advantage of the compact power capacitors. Thanks to the dry technology construction of the components, good heat dissipation, low self-heating and reliable operation at high ambient temperatures are further advantages.

Depending on your requirements, you can obtain multicond power capacitors in different versions from basic to premium. Note: In networks with increased harmonic loads, we recommend the use of power capacitors from the multicond-premium series.

The power capacitors impress with the highest quality on the market, which we guarantee through our own development, production and testing at our factory in Schwabach in accordance with our “Made in Germany” quality promise.
