Project Description

FLP50GR-150/1


Description

Integral housing coordinated lightning current and surge arrester for protecting power supply system against surges.

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