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).
