Surge Protector Type 1+2 TN-S 4 Poles 50kA 230V IP20 Dehn

Description

Dehn shield is a coarse-intermediate protection (Type 1+2). For installations on incoming lines in systems with external lightning protection in lightning protection classes 3-4 (LPL III-V). 4-pole protection for TN-S. Optical indication with green/red indicator flag. With a unique RAC spark gap technology that can be compared to a surge arrester function, you get a very fast response and minimal residual energy compared to traditional varistor technology.
