The FLP50GR line is a group of Class I Surge Protective Devices. They are intended as a protection

against direct hit of lightning strokes of high intensities or in installation with often occurrence of

lightning strokes. In standard three phase TN-C grid, they provides protection over LPL I requirements

given in EN 62305 with total lightning current introduced into electrical installation over 100 kA and total

lightning stroke current 210 or 280 kA based on physical configuration and mutual position of grounding

point of lightning rod, grounding point of the electrical installation and place of SPD installation.

The design of FLP50GR is fully based on Spark Gap solution. It brings very high capability and life time

and full insulation in case of no overvoltage is present. Thus, these SPDs can be used also upstream to

energy meters and 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

0-1 and thus can be hit with direct lightning stroke. Due to the single phase cable, the total lightning current

is split to 3 conductors only and intensity per conductor is thus higher than in the case of ingoing three

phase cable.
