The first feature is a heavy-duty DC disconnect designed for solar PV isolation, which delivers clear, reliable outage capability and reduces risk during maintenance; the business impact is safer operations, faster servicing, and improved uptime for 600 VDC solar circuits in outdoor environments. This unit is rated at 200 A across three circuits and is non-fusible with an ungrounded configuration, meaning system designers can meet NEC requirements while simplifying fault isolation and minimizing arc energy in ungrounded dg configurations. The NEMA 3R enclosure, painted galvanized steel, provides weather-resistant protection for outdoor installations, improving service life and reducing corrosion-related maintenance costs in rooftop or exposed locations. Wire compatibility is a core strength, supporting LC, SR, and EG main lug configurations with sizes from 300 kcmil-#6 to #14 AWG, enabling flexible, field-ready terminations for diverse PV strings. Certifications such as UL 98B and NEC 690 per UL 1741 reinforce compliance, while the Eaton warranty (25-000) offers added assurance and support. This combination of rugged construction and clear electrical ratings translates into measurable efficiency, lower ownership costs, and predictable performance across solar projects.
