Feature → Business Impact → Application: Four-pole, 400 A rating with 600 VDC maximum supports full isolation of solar PV strings and main supply in a single enclosure, reducing switching complexity and improving safety during maintenance. This translates to lower downtime and faster commissioning on 600 VDC systems, especially in multi-string arrays and higher-current configurations. Application: Solar photovoltaic installations and industrial DC protection schemes benefit from a robust, industry-standard disconnect that can handle large conductor sizes without re-termination complexity. Feature → Business Impact → Application: Large main lug wire sizes In/Out LC and In/Out SR accommodate up to 750 MCM conductors, minimizing splices, shortening install time, and reducing connection losses in high-current solar feeders. Application: Heavy-duty solar and battery storage projects where wiring efficiency matters. Feature → Business Impact → Application: NEMA 4 painted galvanized steel enclosure provides reliable outdoor performance against dust, rain, and corrosion, ensuring compliance in harsh plant environments. Application: Outdoor solar yards, rooftops, and outdoor electrical rooms. Feature → Business Impact → Application: Non-fusible protection simplifies maintenance cycles and reduces nuisance tripping in steady-state PV operation, while maintaining safe shutdown capability. Application: Routine maintenance and emergency isolation in solar arrays. Feature → Business Impact → Application: UL Listed certification validates code compliance and reliability, helping projects meet national and local electrical standards, while 600 VDC per pole and four-pole design support robust system protection. Application: Regulatory-compliant solar installations and industrial DC protection. Feature → Business Impact → Application: 125 lb weight and 12.42 in depth facilitate installation planning and mounting flexibility in restricted spaces, enabling easier retrofits and service access. Application: Retrofit projects and modular solar facilities needing reliable, install-friendly DC disconnects.

FAQs
The unit supports In/Out LC terminations of (1) 750 kcmil-1/0 and (1) 600 kcmil-#2, and In/Out SR terminations of (2) 750 kcmil-1/0. This accommodates large-diameter conductors typical in utility-scale and commercial solar installations, reducing the need for splices and enabling a clean, single-point disconnect for each string or channel.
Yes. It features a NEMA 4 enclosure and painted galvanized steel construction designed for outdoor environments. UL Listed for electrical protection, it is built to withstand dust, moisture, and incidental impact, making it well-suited for rooftop and ground-mounted solar PV applications in challenging climates.
The DCG4065UPM is UL Listed and rated for 600 VDC per pole with a four-pole configuration. This combination ensures compliance with safety and performance standards for solar PV systems, provides confidence in electrical protection, and supports code adherence during inspections and audits.
Plan for a space that accommodates a 12.42 in depth by 24.12 in width footprint, with a height of 57.47 in and a 125 lb weight. Ensure accessible disconnecting hardware, proper ventilation, and clear labeling. The unit supports large conductors, reducing the need for mid-run splices, which simplifies layout in tight or modular solar installations.
