GALAXIS switchboard up to 6300A

GALAXIS switchboards combine maximum safety for personnel and equipment with reliability of your electrical installations and sustainability of your investments. Initially designed around a moulded bus bar used in nuclear power plants and O&G, this technology is recognized for the safety of installations provided. GALAXIS’s specific design ensures service continuity of your production and its future evolutions.

Our certifications provide compatibility with the major equipment brands. Equipment is also certified with the GemStart digital thermal protection.

Vertical moulded bus bar – patented solution and unique design

Unparalleled electrodynamic resistance and elimination of the risk of arc translation by maintaining the busbar over its entire length thanks to the molding resin. It also gives it success in the internal arc tests (IEC 61 641) required by petrochemical and nuclear industries (100KA / 1s – 220 KA Base peak). No mechanical maintenance required, this can often be the cause of defects and accidents due to improper tightening.

No risk of deformation of bars, they are blocked in the resin. No risk of dust accumulation (on supports) which in the long term would require maintenance in order to limit the risks of distances reducing necessary for a good level and respect of the dielectrics (often cause of priming).

Manufacturer guarantee

COMECA offers you a Manufacturer guarantee on the assembly of your electrical equipment by ensuring:

  • Assembly supervision
  • Alignment, mechanical coupling
  • Splicing of cells and electrical sheaths

In option:

  • Front end cable connections
  • back end cable connections


iBoard supervision interface

With the iBoard supervision solution designed by Comeca, you have full control in real time of everything that happens on your LV switchboard from your touchscreen interface integrated. The iBoard software monitors the events on your switchboard in real time and warns you with its alert system.

What is BIM? BIM (Building Information Modeling) is the set of tools, objects, methods that allow the digital design of constructions and the management of the life cycle of installations. Learn more on our blog: COMECA provides BIM objects for GALAXIS switchboard

COMECA’s GALAXIS switchboard in BIM object

OMECA provides BIM objects for GALAXIS, in REVIT format. As GALAXIS range is wide and as our switchboards are based on multi-panels solution, the first objects we provide for download are GALAXIS front access ACB and MCC panels. Assembling these panels together in your sketch will give the switchboard you foresee.

  • GALAXIS AF8075M is the ACB panel with mid rear busbar used for ACB rated up to 3200Amps
  • GALAXIS AF1075M is the ACB panel with mid rear busbar used for ACB rated up to 4000Amps
  • GALAXIS MF1075M is the MCC panel with mid rear busbar up to 4000Amps
