EXFS L flameproof line spark gap

Name: EXFS L flameproof line spark gap
Brand: IPSI Solutions
SKU: DIP-038

Réf. DIP-038

Flameproof lightning-protection spark gap (ATEX zone 2) for bridging insulating elements on pipes under cathodic protection. Lightning current 50 kA, IP54.

EXFS L flameproof line spark gap: overview

This line spark gap provides the connection or indirect earthing of insulated installation elements during a lightning strike, as well as the bridging of insulating elements on pipe segments under cathodic protection. It complies with potential equalisation for lightning protection (IEC / NF EN 62305) in explosion-risk zones (zone 2) and with the ATEX directive.

Its die-cast zinc enclosure resists corrosion; it has a plastic cap and a flexible conductor connection, with a design withstanding very high loads. The EXFS L100 / L200 / L300 range offers a lightning current (10/350) Iimp of 50 kA, a nominal discharge current (8/20) In of 100 kA and a continuous voltage of 300 V (marking Ex II 3 G EEx nC II T4, IP54, certification ZELM 03 ATEX 3192X).
