- Application-optimised and prewired spark-gap-based type 1 and type 2 combined lightning current and surge arrester
- Compact design due to space-saving spark gap technology with a width of only 1 module / pole
- Fulfils the minimum requirements on the lightning current discharge capacity according to IEC 60364-5-53
- Allows compact lightning equipotential bonding including protection of terminal equipment
- Discharge capacity up to 50 kA (10/350 µs)
- Operating state / fault indication by green / red indicator flag in the inspection window
- High follow current extinguishing capacity (Ifi = 25 kArms)
Application-optimised and prewired combined lightning current and surge arrester
for single-phase TN systems with a nominal voltage of 230 V (2+0 configuration).
