Combination type
SLP-275-VB/3+1
Order number: A07059
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
