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

Product Description

FLP50GR-275/1+1

Integral housing coordinated lightning current and surge arrester for protecting single-phase TT and TN systems (“1+1” circuit) 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
