Compatible Phoenix Contact SCBs for this application are marked with the addition “EQ” in the item designation.
These SCBs connect the PV strings per position to one potential internally, integrate the surge protection via branch wiring, and then split the PV strings again. The output cables on the SCB must have the same cross-section and the same cable length. In addition, each conductor connected to the SCB should, in the event of a fault, either be able to carry the entire short-circuit current per DC circuit or be protected by fuses of operating class gPV.
