Hakel Combi Set is lightning and surge arrester type 1+2 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 2 (according to IEC 1312-1 and EN 62305) for lightning current equipotential bonding and elimination of switching surges that originate in power supply systems entering the building.
Hakel Combi Set is a combination of the latest technologies where the spark gap combines the varistor. The set contains lightning arresters of HS series and surge arresters of PIII series. HCS can be installed in every common switchboard and its special construction is intended for using in non-measurable parts of electrical systems.
HCS/3+1 can be used in industrial installations such as substations, main switchboards of large industrial structures and also places with high risk of a direct lightning strikes occurance. This device is intended for use in TNS and TT power supply systems.
