This new Combi-Switch was specially designed with installers in mind. It provides the code-required external DC disconnect and protection for the SB6000U Inverter all in one small enclosure. The Combi-Switch allows for up to four PV strings to be landed on individual Touch SafeTM fuse holders.
10 Amp fuses are provided for PV string over-current protection. The fuse outputs are then combined and routed through the disconnect switch. One pair of wires conveniently connects the entire PV array to the SB6000U’s DC inputs. The familiar enclosure is NEMA 3R rated for outdoor installation. Numerous knockout rings are provided for simplified conduit installation.
The Combi-Switch is also ETL listed to UL 1741
