Reactive power compensation directly at the source

multicab-F - Fixed capacitors

Reactive power compensation components
multicab F 050 01 1000 14 SWGH

The multicab-F fixed capacitors compensate the inductive reactive power directly at the point of origin.

The great advantage of fixed capacitors is that they significantly reduce the load on the supply lines to the consumers. Fixed capacitors are used for loads with relatively high power, such as transformers and motors.

In the standard version, you receive the fixed capacitors in a sheet steel wall cabinet according to your requirements.
