60 A, 1 circuit, non-fusible DC disconnect provides straightforward, scalable isolation for a single-string PV setup. The business impact is clear: it minimizes fault propagation, reduces arc-flash exposure, and simplifies preventive maintenance. In grounded PV applications, this configuration supports predictable switching and safer de-energization during servicing. 304 stainless steel construction paired with a NEMA 4X enclosure delivers weatherproof protection and corrosion resistance for outdoor rooftop and ground-mounted installations. The durable enclosure reduces downtime from environmental exposure and extends service intervals, directly lowering lifecycle costs. Isolated return with grounded configuration provides a clearly defined fault path, enhancing system safety during switching in energized PV circuits. This topology aligns with best practices for grounded PV systems and simplifies inspection and testing in regulated facilities. Main lug capacity supports #14-#2 AWG conductors, with solid return options that simplify field wiring and maintain service integrity. The positive lug specification helps installers quickly size conductors, reducing install errors and rework in busy solar sites. Certified to UL 98B and NEC 690 per UL 1741, the unit provides regulatory alignment for PV installations, including utility interconnection readiness. A NEMA 4X enclosure adds ruggedness for outdoor use. These certifications support faster approvals and safer, compliant deployments. The warranty covers one year from installation or eighteen months from shipment, ensuring support through project ramp-up and early operation.
