Product recommendation: DEHNguard ACI

Surge protection always safely dimensioned

The ACI technology - Advanced Circuit Interruption – increases the safety of your electrical installation.

What’s really special about this technology: The integrated switch/spark gap combination of the DEHNguard ACI type 2 arrester makes an upstream fuse superfluous. This saves time, space and material.

Another advantage: Possible errors which may occur when selecting and dimensioning a backup fuse are prevented.
