  • Page 6: Why A Busbar System

    Energy distribution must not only be flexible and low priced, but also space-saving, safe and with a long service life. unibar H busbar systems from Hager are just that: efficient and reliable. With this system energy can be transported and distributed precisely: from the transformer to the low voltage switchgear and through the entire building.
  • Page 7 Why a busbar system? Flexible We comply with the customer’s specifications when creating the routing plan for the busbar system. The route is adapted to local circumstances and can be modified at any time. Modifications and expansions with unibar components are possible at any time after the installation of the busbar trunking system.
