Surge protection for data centres
Our solutions for internal lightning protection reliably protect the electrical and electronic systems of data centres against the effects of lightning strikes and switching operations. This also includes lightning protection equipotential bonding for all conductive systems leading into the building from the outside. You can find out how to design surge protection for your data centre in detail here.
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 arrester 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

The right solutions
DEHNpatch
The DEHNpatch surge arrester protects the latest generation of Ethernet applications up to 10 GBit/s and 4PPoE. This secures the flow of data even after surges or lightning strikes.
DEHNventil M2
This arrester protects against transient overvoltages and creates space for future requirements. DEHNventil M2 ensures the availability of systems and thus ensures smooth processes in modern, networked industrial plants.
