This can be prevented with DEHN surge arresters Type 3 for terminal devices. The surge arresters of the DEHNrail M family are especially designed for protection of terminal equipment in industrial electronic systems. The low voltage protection level as well as the comprehensive protection from common-mode and differential-mode interferences are characteristic of DEHNrail M devices. In order to provide the low voltage protection level for the termin

Surge Arresters for Terminal Equipment Lightning Protection Zone 2/3 Surge arresters Type 3 are required, if > inducted surges between the upstream distribution board and terminal device may come up > sensitive electrical and electronical devices are used. The induction of surges due to the electromagnetic field impulse of lightning depends considerably on the kind of measures taken for room and conductor shielding and on the distance between the affected c

If this is not taken into account, this could lead to an overload of the surge arrester at the terminal
