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 in consumers with relatively high power consumption, such as pumps, machines, and motors.
In the standard version, you receive the fixed capacitors in a sheet steel wall cabinet or as a module according to your requirements.
