Project Description
FLP50GR-385/3+1
Description
Integral housing coordinated lightning current and surge arrester for protecting three-phase TT and TN-S systems (“3+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
