Spark-gap
FLP-SG50 VS/1
Order number: A04053
pluggable module, visual fault signalling, module locking, remote fault signalling
- encapsulated high-performance spark gap
- installation at the boundary of zones LPZ 0 and LPZ 1 or higher, mainly to main distribution boards
- for protection against impact of direct or indirect lightning strikes in the hardest application in heavy, chemical and energy industry
- coordination with SPD type 2 (SLP-275 V) even without surge separating inductors
