Description
Parafoudre 1 pôle Ex9UE type 1, 385 VAC, 35 kA sans signalisation
•Les Atouts de l'article:
The Ex9UE1 35 line is a group of Class I Surge Protective Devices. They are intended as a protection againstdirect hit of lightning strokes of high intensities or in installation with often occurrence of lightning strokes. Instandard three phase TN-C grid, they provides protection over LPL I requirements given in EN 62305 with totallightning current introduced into electrical installation over 100 kA and total lightning stroke current 210 or 280kA based on physical configuration and mutual position of grounding point of lightning rod, grounding point ofthe electrical installation and place of SPD installation.The design of Ex9UE1 35 is fully based on Spark Gap solution. It brings very high capability and life time and fullinsulation in case of no overvoltage is present. Thus, these SPDs can be used also upstream to energy metersand can be intended for IT grids (with respective special tests).The high value of Iimp makes these SPDs suitable also for single phase outlets which are wired out of LPZ 0-1and thus can be hit with direct lightning stroke. Due to the single phase cable, the total lightning current is splitto 3 conductors only and intensity per conductor is thus higher than in the case of ingoing three phase cable.
