Details
DEHNventil ZP combined lightning current and surge arresters are specifically designed for installation in the busbar connection panels of meter panels. They can be directly snapped onto the busbar system without tools. Their compact dimensions leave enough space for the connecting cable from the service entrance box, even if two selective main circuit breakers are installed.
The operating state of the arresters is indicated by an indicator light at the push of a button. Both due to this kind of operating state indication and their design as a spark-gap-based arrester, DEHNventil ZP arresters have no leakage and operating currents.
The RADAX Flow spark gap technology ensures that fuses are not tripped by follow currents even in case of low-current-rated fuses in the service entrance box. Undesirable supply interruptions due to tripped main fuses are thus avoided.
The device parameters and design are fully compliant with all requirements of the German VDN guideline* on the use of surge protective devices in primary power systems.
