PV-DC-Junction box

Part Number 158111
  • Generator junction box for 1 MPP tracker / 4 strings
  • Integrated surge protection device - DS50VGPVS-1000G/12KT1 (Type 1+2)
  • Protection class IP65
  • Connection via spring terminals (6-16mm²)

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)).
