Eaton DCG2105URM DC Disconnect - NEMA 3R, 1000 VDC
Part Number: DCG2105URM
Quick Summary
Eaton DCG2105URM DC disconnect provides a rugged, 400 A switch for DC photovoltaic systems. Engineers often struggle with reliable isolation in outdoor installations while meeting code and safety requirements. UL Listed and a NEMA 3R enclosure support compliant outdoor installation, and the 1000 VDC rating matches modern PV string voltages. This heavy-duty, non-fusible disconnect also supports grounded operation and two circuits, helping you simplify wiring and compliance. For procurement teams, the combination of UL listing, NEMA rating, and 400 A headroom translates to faster sourcing, safer field installations, and reduced project risk. In practice, technicians value quick installation, clear labeling, and a durable enclosure that stands up to harsh environments.
