The upper part of the C20 surge arrester made of halogen-free plastic serves as a replacement part for the V20 SurgeController NPE spark gap. The vibration-proof locking mechanism and the voltage and type coding ensure safety and prevent confusion between the upper and lower parts. The wedge-shaped design of the contacts makes it easy to insert and even easier to remove the upper parts.
