Combination type

SLP-275 VB/3+1

Order number: A03310

pluggable module, visual fault signalling, module locking

  • 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
  • no leakage current
