Tap-off units

The distribution of energy using tap-off units is only possible for a busbar
system with protection type IP55 / IP65 (the busbar system with protection
type IP68 is intended exclusively for energy transport).

Selection, assembly and installation of tap-off units and protective equipment
may only be undertaken by electrical specialists.
