Device installation
Prisma Plus cubicles can be used for installation of the new “Varpact” power factor
correction modules designed to improve power system quality and reduce
consumption of reactive energy.
These modules are made up of capacitors, contactors and special protection against
internal faults. Depending on the version, they come equipped with front busbars or
not.
The following table indicates the maximum number of Varpact modules that can be
installed in one cubicle (D=400 mm or 600 mm) without exceeding temperature rise
limits, as well as the catalogue numbers of the necessary mounting accessories.
