Feature → Business Impact → Application: The DCU2065FPM delivers a 400 A amperage rating and a 600 VDC per pole capability, enabling safe, rapid disconnection of high‑energy PV strings. This translates to improved personnel safety during electrical maintenance and reduced downtime during fault isolation, particularly in utility-scale or roof-mounted solar installations. Feature → Application: Two circuits within a single enclosure support modular PV layouts, facilitating easier expansion and system tuning without added disconnects, ideal for mid-size solar projects and retrofit scenarios. Feature → Business Impact → Application: Fusible protection in a NEMA 4, painted galvanized steel enclosure ensures outdoor durability and robust fault containment, reducing corrosion risk and maintenance costs in harsh environments. Feature → Application: Ungrounded system emphasis aligns with common PV configurations, lowering stray-ground fault concerns and simplifying code-compliant disconnect strategies. Feature → Business Impact → Application: The compact footprint (12.42 in depth, 24.12 in width, 57.47 in height) and 118 lb weight support easier installation, mounting versatility, and reduced installation labor in rooftop or equipment room installations. Feature → Application: UL Listing provides third-party assurance and faster регulatory approvals for solar projects while supporting ongoing compliance, performance predictability, and long-term ROI.
