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.
