With a tested maximum lightning impulse current of 100 kA (10/350 µs), EXFS 100 and EXFS 100 KU meet class H of the protection standard, i.e. the maximum class of lightning impulse current strength according to EN 50164-3 ”Lightning Protection Components (LPC) - Part 3: Requirements for isolating sparkgaps“.
The ATEX-certified spark gaps EXFS 100 and EXFS 100 KU provide approved safety according to harmonised European standards. For connecting EXFS 100 spark gaps, prewired connecting cables with different lengths are available as accessories. Flat and angled connection brackets are also available and make it easier to connect the spark gaps to the pipe flanges.
EXFS 100 KU types spark gap comes with 4m of cable (2m each side of the spark gap) and are enclosed by a damp-proof plastic coating and can therefore be ideally used for underground installation for insulating couplings.
