Surge Arrester – Type 1

Surge Protection Device-FLP100B-255

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

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