Project Description



Integral housing (N-PE spark-gap-based) combined lightning current and surge arrester for protecting TT and TN-S systems (“3+1” circuit) against surges.

  • Prewired spark-gap-based type 1 and type 2 combined lightning current and surge arrester
  • Maximum systems availability due to RADAX Flow follow current limitation
  • Capable of protecting terminal equipment
