3 Ideally suited for residential buildings is a space-saving and application-optimised protection solution for residential buildings. It can be optimally integrated in this field of application without requiring an additional backup fuse*. Installation upstream of the meter panel is fully compliant with the German VDN directive and can thus be installed upstream of the meter panel. This is a significant advantage compared with type 1 varistor-based arresters. Space savings takes up only 4 standard DIN modules and is thus suited for restricted installation situations. Moreover, no additional backup fuse is required up to 160 A. Protection of terminal devices Due to the wave breaker function, reduces the lightning impulse to a minimum, thus preventing negative interaction with the electrical installation. Easy remote monitoring can be easily remotely monitored thanks to the floating remote signalling contact. Optimised protective effect can be connected in series using the STAK 25 terminal, thus ensuring maximum system protection. Numerous fields of application: Buildings with external lightning protection system according to class of LPS III / IV Buildings without external lightning protection system with roof-mounted structures, e.g. antennas or satellite systems** Buildings without external lightning protection system where power is supplied through an overhead line** For protecting outdoor electrical loads, e.g. outdoor lights, charging stations for electric vehicles, barriers * In case if system backup fuses are up to 160 A. ** Recommended according to VdS 2031: Lightning and surge protection in electrical installation. 3

4 lives up to what other arresters promise: Protection of terminal equipment thanks to spark gap technology Spark gap: Comprehensive protection Reduction of the impulse time thanks to wave breaker function Almost no energy load on terminal equipment (red area) Varistor: Insufficient protection Current flows through the terminal equipment over the entire duration of 10/350 μs impulse currents Energy overload or even destruction of terminal equipment (red area) i [ka] total current i [ka] total current current flowing into the device to be protected current flowing through combined arrester (spark gap) current flowing into the device to be protected current flowing through combined arrester (varistor) t [ms] t [ms] Only spark-gap-based combined arresters combine lightning equipotential bonding and protection of terminal equipment in a single device. Benefits of a spark-gap-based arrester over a varistor-based arrester with spark gap Type 1 arrester with varistor Energy coordination with type 1 + type 2 + type 3 arresters Protection of terminal equipment Reduction of the impulse time thanks to wave breaker function No leakage currents and thus ideally suited for use upstream of the meter panel 4
