Eaton DCU2065FRM DC Disconnect - NEMA 3R, 600VDC Fusible
Part Number: DCU2065FRM
Quick Summary
Eaton DCU2065FRM DC disconnect is a heavy-duty DC disconnect built for photovoltaic solar installations. Engineers and maintenance teams struggle with undersized protection, ungrounded DC networks, and hard-to-access isolation points that drive safety risk and costly downtime. UL Listed protection, a NEMA 3R enclosure, and fusible switching provide code-compliant outdoor performance and reliable fault isolation. This design supports 600 VDC per pole across two circuits, enabling scalable PV or energy-storage configurations. By consolidating protection, mounting, and enclosure in one unit, it reduces wiring complexity, speeds installation, and improves system uptime for solar projects.
