Product tip: DEHNguard ACI

Surge protection always safely dimensioned

ACI Technology - Advanced Circuit Interruption - improves the safety of electrical systems.

What is special about it: The switch / spark gap combination integrated in type 2 arrester DEHNguard ACI makes upstream fuses superfluous. This saves you time, space and material.

A further bonus: You eliminate those configuration errors which can otherwise be made when selecting and dimensioning a backup fuse.
