The DEHN EXFS L300 is an ATEX-certified spark gap designed specifically for use in Explosion Protection Zone 2 (gases). It provides safe lightning protection potential equalization in accordance with DIN EN 62305 / VDE 0185 and enables the indirect connection or grounding of operationally separated system parts during lightning strikes. The robust design with flexible conductor connection ensures reliable and maintenance-friendly installation in explosive environments. The spark gap prevents unwanted current transfer between electrical systems without impairing the functionality of the separated system parts, thus protecting against dangerous sparking and potential differences.
