EXFS 100 / EXFS 100 KU For use in hazardous areas ATEX and IECEx-certified isolating spark gap with low sparkover voltage for lightning equipotential bonding according to IEC 62305 Lightning Equipotential Bonding Isolating Spark Gaps • For indirect connection/earthing of functionally isolated parts of installations under lightning conditions • Device for lightning equipotential bonding according to IEC 62305 in hazardous areas • For bridging insulating pieces, insulating flanges etc. in cathodically protected pipe sections • For safe installation in Ex zone 1 (gas) or 21 (dust) • Especially low sparkover voltage • Especially high a.c. current withstand capability • Approval according to "ATEX Directive" 94/9/EC and IECEx EXFS 100: Isolating spark gap for use in hazardous areas with plastic sheath and M10 threaded bushings EXFS 100 KU: Isolating spark gap for use in hazardous areas with two 2 m long connecting cables for underground installation The Ex isolating spark gaps of the EXFS 100 / EXFS 100 KU product family are used when conductive installation components situated in hazardous areas cannot be connected directly with each other. The spark gaps with low sparkover voltage are especially efficient for isolated parts of installations with low insulation resistance. No special requirements have to be observed for safe application in zone 1 (gases) or zone 21 (dusts). With a maximum lightning impulse current of 100 kA (10/350 μs), EXFS 100 and EXFS 100 KU meet class H according to EN 50164-3 "Lightning Protection Components (LPC) – Part 3: Requirements for isolating spark gaps". The ATEX and IECEx-certified EXFS 100 and EXFS 100 KU spark gaps provide approved safety according to harmonised European standards. For connecting EXFS 100 spark gaps, prewired connecting cables of different lengths are available as accessory. Flat and angled connection brackets (IF) allow to easily connect the spark gaps to pipe flanges. EXFS 100 KU types are enclosed by a moisture-proof plastic sheath and are therefore ideally suited for underground installation on insulating couplings.
