Lightning current discharge

N-PE SURGE PROTECTION DEVICE with circuit composed of self-extinguishing spark gap, for the overvoltage protection of BT users, even with direct discharges; for use between the protection zones at the 0A - 1 crossings, in particular in the TT network in the 3+1 circuit between the N conductor (neutral) and the PE protective conductor (equipotential). Built according to DIN VDE 0675 part 6-11: 2002-12, CEI EN 61643-11: 2002-05 and IEC 61643 part 1: 1998-02.
