Eaton DCU3061UWM Heavy Duty DC Disconnect - NEMA 4X 600V
Part Number: DCU3061UWM
Quick Summary
The Eaton DCU3061UWM heavy duty DC disconnect safely isolates 600 VDC solar circuits for robust PV installations in commercial and industrial sites. With harsh environments and demanding uptime requirements, field failures, corrosion, and ingress-related faults are common pain points that disrupt production. UL 98B and NEC 690 per UL 1741 compliance, plus a NEMA 4X stainless enclosure, provide outdoor reliability against water, dust, and corrosion. This configuration delivers reduced maintenance, safer DC switching, faster installation, and easier servicing for field technicians in solar, telecom, and industrial power applications. Ideal for solar PV installations, it reduces maintenance costs while boosting uptime, thanks to non-fusible protection, rugged 304 stainless steel construction, and proven Eaton engineering.

FAQs
Install the DCU3061UWM in a suitable PV enclosure, verify clearance for 600 VDC, and connect the main lugs to #14-#2 AWG wiring (with #14-1/0 AWG for the solid return as specified). Ensure the device is mounted in a protected, NEMA 4X environment and follow manufacturer mounting dimensions and torque values for safe operation.
Ungrounded means the disconnect is designed to interrupt the DC path without a bonded neutral ground in the enclosure. This configuration reduces potential ground fault pathways in PV circuits, while it requires upstream protection and proper bonding practices. Regular inspection of lug connections and enclosure integrity is recommended to maintain safety and reliability.
The unit complies with UL 98B and NEC 690 per UL 1741, ensuring safe installation and operation within solar systems. It also carries a NEMA 4X enclosure rating, providing protection against water ingress and corrosion in outdoor environments, which is critical for long-term reliability in harsh sites.
Yes. The DCU3061UWM uses a 304 stainless steel NEMA 4X enclosure designed for outdoor use, offering corrosion resistance and weatherproof sealing. This makes it well-suited for rooftop and ground-mounted solar installations, as well as other outdoor DC power-distribution scenarios.
The product carries Eaton’s warranty policy, which is one year from the date of installation or eighteen months from shipment, whichever occurs first.
