- 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 TT and TN systems with a nominal voltage of 230 V (1+1 configuration); with floating remote signalling contact
Application-optimised two-pole combined arrester for 230/400 V TT systems With remote signalling contact for the monitoring device (floating changeover contact) SPD type 1 + type 2 in accordance with EN 61643-11 For use in compact and simply equipped electrical installations with reduced technical requirements Spark gap technology with follow current limitation Operating state/fault indication by indicator flag in the inspection window Leakage-current-free, non-exhausting design Max. continuous operating voltage: 255 V a.c. Voltage protection level: <= 1.5 kV Lightning impulse current (10/350): 25 kA Energy coordinated in accordance with IEC 62305-4 (VDE 0185-305-4) with type 2 and 3 arresters of the Red/Line family, as well as directly coordinated with terminal equipment DIN rail mounted device in accordance with DIN 43880, 2 modules
