Project Description

FLP25GR-150/4


Description

Integral housing combined lightning current and surge arrester for protecting three-phase TN-S systems 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
