SURGE ARRESTER FOR HOUSES PS4-VA/TT+FS

The surge protector PS4-VA TT+FS is a type 1+2 surge protector. Type 1+2 surge protectors are combined protectors for lightning and surge protection. When a direct lightning strike hits a building protected by external lightning protection, large potential differences can arise between the building and installed systems (electrical, telecommunications cables), leading to dangerous fires and damage. Nearby lightning strikes generate strong magnetic fields that can damage electrical equipment. But even lightning strikes up to 2 km away can generate dangerous surges in the building’s electrical equipment. OBO provides all necessary products for reliable lightning protection: lightning arresters, surge protectors, potential equalization and grounding accessories.
