A solar PV system typically has two safety disconnects. PV or DC disconnect (or Array DC Disconnect) and AC Disconnect. The PV disconnect allows the DC current between the modules (source) to be interrupted before reaching the inverter. The DC disconnect is sized based on the output current of the Photovoltaic String. Core features Offers bi-directional functionality, which breaks the arc regardless of normal or reverse current flow Includes all required components to meet NEC article 690 requirements, including jumpers and labels Guards against accidental contact with live parts with clear polycarbonate deadfronts
