PV-DC-Junction box

GAK2.K2x10.K1x10.DP6-1-XS
Part Number 157208
GAK2.K2x10.K1x10.DP6-1-XS

With the generator junction boxes of the GAK2-XS series, CITEL offers a solution to protect photovoltaic systems against the effects of lightning and surges. The GAK2-XS series is designed for the protection of 2 MPP tracker and maximum system voltages (Ucpv) up to 1200 Vdc. Depending on the configuration, the GAK2-XS are optimised for PV systems on buildings of lightning protection class III/IV with ≥ 4 down conductors in accordance with Table 2, VDE 0185-305 Supplement 5, Fpr TS 50539-12 : 2013 and ground-mounted PV systems.
