Surge protection for data centres
Internal lightning protection measures offer comprehensive protection of the electrical and electronic systems during lightning strikes and switching operations.
The lightning equipotential bonding is designed for all conductive systems running from the outside into the building.

3 stages for full surge protection
An effective surge protection concept has three protection stages. Stage by stage, the penetrating energy is broken down to a safe degree, so that terminal equipment is secure. The best protective effect is achieved when all protection stages are optimally harmonised. Crucial here is that the arresters of the individual stages are energy-coordinated as per DIN VDE 0100-534.
Stage 1
Type 1 lightning current or
combined arrester
at the point where conductors
enter the building
Stage 2
Type 2 surge arrester
in the sub-distribution board
Stage 3
Type 3 surge arrester
directly on the terminal device or
socket outlet
