HS100i is a lightning current arrester type 1 and class I according to EN 61643-11 and IEC 61643-1. These are recommended for use in the Lightning Protection Zones Concept at the boundaries of LPZ 0 to 2 (according to IEC 1312-1 and EN 62305) for lightning current equipotential bonding in power supply systems entering the building. Type 1 lightning current arresters are used for lightning protection equipotential bonding to VDE 0185-305 (IEC 62305)
The lightning current arresters are constructed as an encapsulated spark gap technology for installation in main switchboards. For TNS and TT systems it is necessary to combine these arresters with lightning current arrester HS50-50i which is recommended for equipotential bonding between N and PE.
The main use of HS100i is in industrial installations such as transformers, the main switchboards of large industrial buildings and places with high risk of a direct lightning strike and with an external lightning protection of the highest class I to IV. It is also suitable for applications in unmeasured parts of electrical installation.
