PV-DC-Junction box
Part Number: 158406
GAK1.K4x16.K2x16.S.51-1
- Generator junction box for 1 MPP tracker / 4 strings
- Surge protection integrated (DS50PVS-1000G/51, type 2)
- With string fuses (10x38 in +/- pole)
- Protection class IP65
- Connection via screw/spring terminals
With the generator junction boxes of the GAK1 series, CITEL offers a solution to protect all kinds of photo-voltaic systems against the effects of lightning and overvoltage. The GAK1 series is designed to protect 1 MPP tracker and maximum system voltages (Ucpv) up to 1200 Vdc. Depending on the configuration, the GAK1 meets the normative requirements for all types of buildings with or without external lightning protection system up to lightning protection class I (Iimp = 12.5 kA / pole (10/350)).
