DS252VG-1000 is a 1-phase 2-wire (L+N) surge arrester set combined from two Citel DS250VG-1000 modules, in which each module will protect each different power wire (L or N).
With high-performance VG technology from CITEL France, they are capable of operating strongly and effectively to protect the source or places with high lightning density, with the presence of early emission lightning rods on the construction.
