Product description

Product description

Spark gap for potentially explosive areas, Zone 1/21 and 2/22, for indirect bridging of insulating flanges and insulating threaded joints, e.g. in cathodically corrosion-protected (CCP) systems. For indirect connection of operationally separated system sections during lightning impact. Use according to lightning protection equipotential bonding in accordance with DIN EN 62305/VDE 0185. Suitable for installation in interior and exterior areas and in wet rooms. Particularly low rated contact surge voltage.
