Eaton DCU2064UXM DC Disconnect - NEMA 4X 600VDC
Part Number: DCU2064UXM
Quick Summary
The Eaton DCU2064UXM heavy‑duty DC disconnect provides safe isolation for solar DC systems. When electric fleets rely on ungrounded DC circuits outdoors, corrosion, moisture ingress, and harsh environments can trigger costly downtime. This unit carries NEC 690 per UL 1741 and UL 98B certifications, and its NEMA 4X, 316 stainless enclosure resists weather and corrosion, ensuring long service life in demanding installations. The combination of a 200 A amperage rating, 600 VDC maximum, and two circuits delivers scalable protection for commercial solar arrays, helping engineers meet compliance while reducing maintenance cycles and total cost of ownership. Its non‑fusible, ungrounded design simplifies integration with existing solar power racks and supports fast, reliable isolation during fault conditions.

FAQs
Install the DCU2064UXM into a weatherproof NEMA 4X enclosure and ensure proper mounting clearance. Use the available lug configurations (LC SR EG) to connect conductors per the 300 kcmil-#6 and smaller ranges specified. Verify polarity, verify that the system is de‑energized during installation, and follow NEC 690 guidance for PV applications.
The DCU2064UXM is rated for 200 A and 600 VDC per pole, with two circuits total. It supports main lug wiring in LC, SR, and EG configurations, accommodating in‑range conductors from 300 kcmil down to #4‑#14 AWG depending on the section. This enables flexible wiring for both large and small solar strings.
Yes. It features a NEMA 4X enclosure and 316 stainless steel construction, designed for outdoor exposure and corrosive environments. The unit is intended for solar PV applications, providing ungrounded, non‑fusible isolation up to 600 VDC and 200 A, helping ensure reliable performance in rooftop and ground‑mounted arrays.
The DCU2064UXM carries NEC 690 compliance per UL 1741 and UL 98B, alongside a NEMA 4X enclosure and stainless steel construction. These certifications matter because they validate safe operation with solar PV systems, protect personnel, and ensure compatibility with regional electrical codes, reducing project risk and improving acceptance by inspectors and procurement teams.
Eaton provides a warranty per policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first. This warranty supports reduced maintenance costs and predictable TCO by covering manufacturing defects and performance issues, contributing to longer asset life and lower risk of unexpected repair expenditures in solar installations.
