Eaton DCG1101URM DC Disconnect - NEMA 3R, 1000 VDC
Part Number: DCG1101URM
Quick Summary
Eaton DCG1101URM DC disconnect provides rugged, code-compliant isolation for grounded PV systems. A common challenge in outdoor solar setups is balancing weather protection with quick, reliable wiring and maintenance access. This unit is certified for NEC 690 per UL 1741 and UL 98B and is housed in a NEMA 3R enclosure to withstand rain, dust, and corrosion. For installers, the 30 A rating and single circuit configuration simplify field wiring, while #14-#2 AWG lug capacity and an isolated return improve reliability. By aligning with standard solar installation practices, it reduces commissioning time, enhances safety, and supports long-term uptime across rooftop or ground-mount PV projects.
