As a rule, the radio base station is supplied via a separate power line - independent of the rest of the building. The supply line to the cell site downstream of the meter and in the AC sub-distribution board upstream of the radio base station should be protected by appropriate lightning current and surge arresters.
Prevent nuisance tripping of system fuses
The infrastructure in main and system power supplies is protected by tried and tested combined arresters (combined lightning current and surge arresters).
DEHN combined arresters have an extremely high follow current extinction and limitation. This avoids nuisance tripping of system fuses which would disconnect cell sites. For you, this means especially high system availability.
