These solar disconnect switches for solar photovoltaic (PV) circuits have been introduced by Eaton. They are UL 98 listed and are labeled for NEC Article 690 PV applications per UL 1741 requirements. The switches have multiple factory-wired poles and factory-installed jumpers. They include a neutral block for grounded conductors, equipment-grounding lug, and clear polycarbonate dead front shield to prevent accidental contact with live parts. Only one fuse is required in these fused-style switches, and fuse clips are located on the center pole, away from potential back-feed. The switches are available from 30 to 600 amps and in a variety of enclosure styles.
