Eaton DCU2065UXM DC Disconnect Heavy Duty - NEMA 4X
Part Number: DCU2065UXM
Quick Summary
DC disconnect solutions like the Eaton DCU2065UXM reliably isolate solar DC circuits in PV installations. Engineers often struggle with safe isolation in ungrounded, non-fusible DC systems exposed to harsh environments, where corrosion and weather can threaten reliability. This unit is UL Listed and built in a NEMA 4X, 316 stainless steel enclosure to withstand outdoor and dirty conditions. For businesses, that means consistent protection, reduced downtime, and easier compliance in solar farm or rooftop projects. By pairing rugged construction with a clear 600 VDC rating and 400 A capacity, it supports scalable solar protections while aligning with procurement needs and lifecycle cost goals.
