Eaton DCG2101UPM DC Disconnect - NEMA 4 Enclosure
Part Number: DCG2101UPM
Quick Summary
The DCG2101UPM by Eaton is a heavy-duty DC disconnect for solar PV installations. Engineers often struggle with achieving safe enclosure, reliable isolation, and code-compliant protection in outdoor environments. UL 98B and NEC 690 per UL 1741 certifications ensure safety and alignment with industry standards, while a NEMA 4 painted galvanized steel enclosure delivers weather resistance. Designed for 1000 VDC systems and two circuits, it offers rugged protection with straightforward installation for industrial solar projects and automated facilities. The grounded, isolated return configuration enhances servicing safety, and the 30A rating provides a practical balance between performance and wiring simplicity.

FAQs
DCG2101UPM supports two circuits with a maximum amperage rating of 30 A and a 1000 VDC system voltage. It uses #14-#2 AWG lugs for both main conductors and solid returns, and features an isolated return with a grounded system for safer servicing in solar installations.
The unit is non-fusible with a grounded, isolated return, reducing potential fault propagation. UL 98B and NEC 690 per UL 1741 compliance, combined with a NEMA 4 enclosure, ensure weather resistance and safe operation in outdoor solar deployments.
Compatibility is supported through its standard lug sizing (#14-#2 AWG) and two-circuit configuration. The 25.5 in L x 13.25 in W x 9 in H enclosure and 40 lb weight simplify field handling and fit typical equipment rooms or outdoor enclosures.
Key certifications include UL 98B, NEC 690 per UL 1741, and NEMA 4 enclosure rating. These ensure compliance with common solar installation codes, safe operation under expected environmental conditions, and reliable outdoor performance.
With a one-year warranty and durable painted galvanized steel enclosure, maintenance needs are low. The non-fusible design reduces replacement complexity, while reliable isolation minimizes downtime and supports long-term return on investment in solar assets.
