Zone transitions <strong>and</strong> protective devicesBenefits of the lightning protectionzone concept• Minimisation of the couplingsinto other cable systemsthrough arresting the energyrich,dangerous lightning currentsdirectly at the point thecables enter the building.• Malfunction prevention with -magnetic fields.• Economic, well-plannable individualprotection concept fornew <strong>and</strong> old buildings <strong>and</strong> reconstructions.Type classes of the surge protectiondevices<strong>OBO</strong> surge protection devices areclassified in accordance with DINEN 61643-11 into three type classes− Type 1, Type 2 <strong>and</strong> Type 3(previously B, C <strong>and</strong> D). Thesest<strong>and</strong>ards contain building regulations,requirements <strong>and</strong> tests forsurge arrestors used in AC networkswith nominal voltages of upto 1,000 V <strong>and</strong> nominal frequenciesof between 50 <strong>and</strong> 60 Hz.This classification enables arrestorsto be matched to differentrequirements with regard to location,protection level <strong>and</strong> currentcarryingcapacity. The table belowprovides an overview of the zonetransitions. It also shows which<strong>OBO</strong> surge protectors are to be installedin the energy supply network<strong>and</strong> their respective function.Planning aid, general<strong>information</strong>02 TBS-Katalog_2010_Neuer_St<strong>and</strong> / en / 30/03/2010 (LLExport_00986)Zone transitionsZone transitionLPZ0 B to LPZ1Zone transitionLPZ1 to LPZ 2Zone transitionLPZ2 to LPZ 3Protection device for lightning protection equipotential bonding in accordance with DIN VDE 0185-3 for direct orclose lightning strikes.• Devices: Type 1 (Class I, requirements class B), e. g.
