Eaton DCG3104URM DC disconnect - NEMA 3R 1000V
Part Number: DCG3104URM
Quick Summary
Eaton heavy duty DC disconnect isolates DC circuits for solar PV installations with reliable, rugged performance. In field installations, teams face weather exposure, high current transients, and the risk of arc faults that can drive downtime. This model offers a 200 A, 3-circuit, grounded, non-fusible solution with a 1000 VDC rating inside a NEMA 3R, painted galvanized steel enclosure. The wiring options support LC, SR, and EG terminations, simplifying retrofit and new install across PV arrays of varying sizes. Certified to NEC 690 per UL 1741 and UL 98B, it helps meet utility-scale, commercial, and industrial safety standards while minimizing maintenance overhead. By combining rugged construction with flexible wiring and clear documentation, engineering teams can accelerate commissioning and reduce total cost of ownership.
