Eaton DCU3062UPM DC Disconnect - NEMA 4, 600 VDC
Part Number: DCU3062UPM
Quick Summary
DC disconnects provide safe, rapid isolation for solar PV DC circuits, enabling safe maintenance and compliant shutdown of PV arrays. A common challenge is finding a rugged, weather-resistant enclosure that fits standard wiring while meeting electrical codes in outdoor environments. This Eaton DCU3062UPM unit combines a heavy-duty 60 A, 3-circuit disconnect with a NEMA 4 painted galvanized steel enclosure, UL 98B and NEC 690 per UL 1741 compliant. It supports ungrounded configurations and non-fusible protection, making field service straightforward. By delivering robust construction, documented wiring options, and a clear warranty, the design reduces commissioning risk and accelerates project timelines. For solar projects, it translates to predictable performance and lower lifecycle costs compared with multi-part assemblies.

FAQs
The DCU3062UPM supports 3 ungrounded circuits with a 60 A rating and a 600 VDC per pole limit. It provides main lug capacities for #14-#2 AWG wiring and a solid return up to #14-1/0 AWG, enabling straightforward integration with common PV conductors while maintaining code-compliant disconnect isolation.
With a 60 A current rating and 600 VDC per pole, the DCU3062UPM suits PV strings and subarrays within these electrical limits. Designers must ensure that the sum of concurrent currents does not exceed 60 A per switch position and that the system voltage does not surpass 600 VDC, aligning with NEC requirements for DC equipment.
Yes. Its NEMA 4 enclosure, painted galvanized steel construction, and outdoor-rated design make it well-suited for rooftop and ground-mounted PV installations. The unit is built to withstand weather exposure while providing reliable isolation, meeting UL 98B and NEC 690 per UL 1741 references for solar applications.
The DCU3062UPM adheres to UL 98B and NEC 690 per UL 1741, supporting safe, code-compliant operation in PV systems. The NEMA 4 enclosure further confirms suitability for outdoor environments, reducing compliance risk during procurement and installation.
As a non-fusible disconnect, routine maintenance focuses on mechanical and enclosure integrity rather than fuse replacement. The unit carries a one-year warranty (or 18 months from shipment), and its robust steel enclosure, wiring flexibility, and standardized dimensions help minimize on-site modifications, contributing to lower lifecycle costs and faster ROI for solar projects.
