PV-DC-Junction box

GAK6.K4x16.K1x16.DP40VG-1-XS

Part Number 157607

With the generator junction boxes of the GAK1 series, CITEL offers a solution to protect photovoltaic systems against the effects of lightning and surges. The GAK1 series is designed for the protection of 1 MPP tracker and maximum system voltages (Ucpv) up to 1200 Vdc. Depending on the configuration, the GAK1-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.
