Presentation
Schneider Electric offers power factor correction equipment that integrates perfectly
in Prisma Plus switchboards.
The power factor correction modules are installed horizontally in a cubicle and
electrically interconnected by a set of front busbars.
The busbars are supplied by a protection device installed outside the cubicle.
Special Prisma Plus cubicles are used for power factor correction, given the
temperature rise inside the cubicles.
They comply with and are tested according to standard IEC 60439-1.
Installation
Mounting plates are equipped with the power factor correction modules, made up of
a contactor, the corresponding protection fuses and a set of busbars.
They are installed in a 650 mm wide cubicle that is either 400 or 600 mm deep
depending on the depth of the switchboard to which it will be added.
Each cubicle can be equipped with up to 5 or 4 Varpact Classic or Comfort power
factor correction modules or up to five Varpact Harmony power factor correction
modules, positioned one above the other.
The cubicle has a ventilated roof that can be equipped with one or two fans.
The door has cut-outs, one for the Varlogic power factor controller and another in the
bottom for a filter.
