Eaton DCG2065UPM Heavy Duty DC Disconnect - UL Listed
Part Number: DCG2065UPM
Quick Summary
DCG2065UPM heavy duty DC disconnect isolates solar DC circuits safely in PV installations. Engineers often wrestle with bulky enclosures, wiring complexity, and inconsistent ratings when integrating large DC arrays. UL Listed and NEMA 4 enclosure labeling provide weather resistance and regulatory compliance for outdoor and harsh-industrial sites. This solution supports 400 A, 600 VDC operation and two-pole, grounded, isolated-return architecture, simplifying wiring with clearly defined lug configurations. By combining rugged construction with clear documentation, Eaton helps reduce install time, improve safety, and boost system availability in commercial solar projects.

FAQs
Installation requires lockout/tagout procedures and power彻to be de-energized before work. Use proper torque on In/Out lug connections sized up to 750 MCM for LC and 600 MCM-#2 for SR, and mount within a NEMA 4 enclosure. Follow Eaton wiring diagrams and 600 VDC safety practices to ensure a safe, isolated return and compliant operation.
DCG2065UPM delivers 400 A at 600 VDC across two poles with non-fusible protection and a grounded, isolated return. It supports In/Out LC connections of 750 MCM-1/0 and 600 MCM-#2, and In/Out SR paths for two 750 MCM-1/0 conductors, making it suitable for large DC feeders in solar arrays.
Yes. The unit uses a NEMA 4 enclosure with painted galvanized steel, is UL Listed, and is engineered for outdoor solar installations. Its grounded isolation, rugged construction, and large conductor accommodations make it appropriate for rooftop and ground-mounted PV systems in challenging environments.
The DCG2065UPM is UL Listed and designed for a NEMA 4 rating enclosure. These certifications support regulatory compliance and safe operation in outdoor and industrial solar deployments, aligning with common safety and reliability requirements in commercial projects.
The heavy-duty construction reduces replacement frequency, while the non-fusible protection and isolated return simplify servicing and fault diagnosis. The UL Listed, weather-ready enclosure supports long service life in harsh environments, contributing to improved system availability and a favorable total cost of ownership.
