EXFS L / EXFS KU For use in hazardous areas Lightning Equipotential Bonding Isolating Spark Gaps • For indirect connection/earthing of functionally isolated parts of installations under lightning conditions • For lightning equipotential bonding according to IEC 62305 in hazardous areas (zone 2) • Corrosion-resistant zinc die-cast enclosure with plastic cover and flexible conductor connection • For bridging insulating pieces, insulating flanges etc. in cathodically protected pipe sections • Extremely heavy-duty device • Approval according to ATEX directive 94/9/EC and IECEx ATEX and IECEx-certified isolating spark gap for lightning equipotential bonding according to IEC 62305 with flexible conductor connection EXFS L ...: Isolating spark gap for use in hazardous areas with flexible connecting cable EXFS KU: Isolating spark gap for use in hazardous areas with two 1.5 m long connecting cables for underground installation Ex isolating spark gaps of the EXFS L / EXFS KU product family are used when electrically conductive parts of installations cannot be directly interconnected in hazardous areas, for example, in case of cathodically protected pipeline sections. ATEX and IECEx-certified EXFS L and EXFS KU spark gaps provide approved and tested safety in accordance with harmonised European standards. The arc-resistant tungsten-copper electrodes ensure a long service life of the Ex spark gaps. The approved EXFS L type with flexible conductor connection quickly adapts to any application environment. The prewired spark gaps feature connecting cables of different lengths with cable lug, screw and M10 nut. The flat or angled connection brackets (IF), which are available as accessory, allow to easily connect the spark gap to pipeline flanges. The EXFS KU type is enclosed in a moisture-proof PVC enclosure and is ideally suited for underground installation on insulating couplings.
