HGDT100

HGDT100 is the encapsulated gas discharge tube Type 1+2 according to EN 61643-11 and IEC 61643-11. These arresters are recommended for use in the Lightning Protection Zones Concept at the boundaries of LPZ 0-1 and higher (according to IEC 62305 and EN 62305), in the power supply lines, which are operated as TN-S and TT systems, where they provide the equipotential bonding between N and PE in the connections of 3+1. Thanks to the high insulation resistance at the release condition, the GDT will not cause the activation of RCD (residual current-operated protective device). The position of the applied HAKEL SPD may be horizontal, vertical, rotated 90 or 180 degrees, and this position does not affect the SPD’s function or the specified parameters.

Note: A special variant of gas discharge tubes is used for IT power supply systems.
