Surge protection for The power supply unit of a cell site has a separate feeder
cable that is independent from the power supply unit of the

a.c. applications building. DEHN combined arresters feature sufficient follow
current extinction. This is the only way to prevent false trip-
ping of system fuses and disconnection of the cell site, thus
increasing system availability.
