Project Description
FLP25GR-150/1
Description
Integral housing combined lightning current and surge arrester for protecting power supply system 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
