- Test in accordance with EN 61643-11 & IEC 61643-1, ÖVE 8001-1
RANGE OF APPLICATION
SG50 used in combination with COMBTEC VV, VS, G100 in combination with PROTEC, POWERTEC in 3 + 1 switching operation is used to protect against direct lightning strikes in external overhead lines or external lightning arrester in the TT system. See graphic for application.
SG 50, G 100 are 1-pole N/PE lightning arresters with protection class I+II+III (B+C+D) for protection against partial lightning currents from entering electrical installations. The device is used for equipotential bonding of lightning protection in the 400/230 VAC TT system, as a N/PE conductor with 3 + 1 switching operation.
It is able to deflect lightning currents up to 50 kA / 100 kA (10/350 μs) with a charge of 50 As, and has a low protection level, Up < 1,5 kV. The use of a hermetically-sealed high-performance spark-gap filled with inert gas makes use of a dangerous blow-out opening superfluous.
