Eaton DCU2065FWM DC Disconnect - NEMA 4X, 600 VDC
Part Number: DCU2065FWM
Quick Summary
DC disconnects provide safe power isolation for high-current solar PV installations. Engineers often confront bulky enclosures and corrosion risks in outdoor or washdown sites, complicating installation schedules. UL Listed and NEMA 4X protection ensure reliable performance in demanding environments, backed by 304 stainless steel construction. With a 400 A rating and two circuits, the DCU2065FWM supports substantial solar arrays while enabling straightforward, safe isolation of 600 VDC per pole. This combination delivers safer, faster installations and long-term cost savings for your project. For procurement teams, the UL listing, NEMA 4X enclosure, fusible configuration, and stainless steel construction translate into lower lifecycle risk and maintenance overhead.

FAQs
The DCU2065FWM is designed for two circuits and 600 VDC per pole in ungrounded solar configurations. Installers should plan for a NEMA 4X, 304 stainless steel enclosure in outdoor or washdown environments, ensuring proper mounting, cable routing, and compliance with UL Listed requirements to maximize safety and uptime.
Key specs include a 400 A amperage rating, two circuits, 600 VDC per pole, fusible protection, and a NEMA 4X enclosure made from 304 stainless steel. The device is intended for solar applications and provides safe isolation for high-current DC power with reliable, field-serviceable components.
Yes. The enclosure is NEMA 4X rated and constructed from 304 stainless steel, delivering corrosion resistance and washdown durability ideal for outdoor solar sites. Its fusible, ungrounded two-pole design supports safe isolation of 600 VDC systems with UL Listed certification for compliance.
The fusible protection and heavy-duty construction reduce fault propagation and downtime. The 304 stainless steel, along with NEMA 4X enclosure, minimizes corrosion during maintenance cycles, while UL Listing assures regulatory compliance. This translates to safer operations and lower lifecycle maintenance costs over the system’s lifetime.
Absolutely. By consolidating protection into a single two-circuit, 400 A device, installers save on hardware, reduce installation time, and minimize service intervals. The rugged enclosure and UL certification lower risk, leading to faster commissioning and longer intervals between maintenance, delivering tangible lifecycle cost savings.
