Circuit Interruption

The backup fuse is already integrated here. This means: reduced space requirement, lower installation costs, faster wiring, and shorter connecting cables. This concept can be found in the product ranges DEHNvenCI, DEHNbloc Maxi S, DEHNguard ... CI and V(A) NH...

Wave breaker function

In the case of spark-gap-based type 1 arresters, the entire current flows through the type 1 arrester during the discharge process. Like a wave breaker, the incoming energy is greatly broken down, which significantly relieves the downstream SPDs. All type 1 arresters in the Red/Line product range feature the WBF wave breaker function.
