Pluggable module, visual fault signalling.
- Combination of combined type surge arrester (serial combination varistor+GDT) and encapsulated spark gap, connected in the 3+1 mode.
- Installation to LV installations, especially to sub-distribution boards in areas with unstable grid voltage and where diesel generators are used, suitable also for measuring circuits.
- For protection of the installations and equipments against impact of induced overvoltages during a lightning strike in areas with higher storm activity or switching overvoltages or as the first stage of for protection for measuring circuits.
- Zero leakage current.
