Eaton Specification Sheet - DCG2104UWM
Selling Policy 25-000 - Distribution and Control Products and Services
The 200 A rating with a two-circuit design provides direct protection for solar DC strings, non-fusible and with an isolated return. This arrangement limits fault propagation, enables safer maintenance, and simplifies field terminations by allowing segments to be serviced independently. In practical terms, technicians can disconnect a single string without de-energizing the entire DC array, reducing downtime during commissioning, troubleshooting, or routine servicing. The DCG2104UWM is purpose-built for solar PV configurations, delivering reliable protection for rooftop, carport, and utility-scale installations while supporting fast, code-compliant commissioning. Enclosure and materials: The 304 stainless steel, NEMA 4X-rated enclosure delivers exceptional outdoor corrosion resistance and suitability for harsh environments. This robustness lowers maintenance costs, extends service life, and minimizes field retrofit work. For outdoor PV farms, rooftop arrays, or industrial facilities, the unit withstands exposure to humidity, salt spray, and temperature cycling without sacrificing performance. The design also supports straightforward mounting and wiring, helping installers meet tight project schedules while maintaining reliable DC protection across the system. Electrical ratings and compliance: With a maximum voltage of 1000 VDC and a grounded isolated return, this disconnect aligns with NEC 690 PV requirements and UL 98B safety standards. The DCG2104UWM is UL 1741 compatible for solar applications, simplifying approvals and installation in regulated environments. Lug configurations and installation practicality: Main lug options include LC, SR, and EG, supporting in- and out-size ranges: LC in 300 kcmil-#6 out 300 kcmil-#6; SR in 300 kcmil-#6 out 300 kcmil-#6; EG in #4-#14 AWG out 1/0-#14. This flexibility enables easy retrofits and new builds, with ample headroom for field terminations, while the 57.47 in length and generous enclosure space simplify routing in restricted spaces. Warranty and lifecycle: Eaton’s warranty policy spans one year from installation or 18 months from shipment, whichever comes first, backing long-term performance.

FAQs
The DCG2104UWM is ideal for outdoor solar PV installations, including rooftop arrays, carport systems, and utility-scale solar farms. Its 200 A rating and two circuits provide direct DC string protection with an isolated return for safer maintenance and rapid fault isolation in harsh environments.
The unit supports LC, SR, and EG main lug configurations. LC is rated for in 300 kcmil-#6 out 300 kcmil-#6, SR for in 300 kcmil-#6 out 300 kcmil-#6, and EG for in #4-#14 AWG out 1/0-#14. Choose the lug type based on conductor size, then route terminations to the isolated return and grounding as specified by the installation drawings.
Yes. It is rated UL 98B and NEC 690 per UL 1741, with UL 1741-ready compatibility. The enclosure is NEMA 4X and manufactured from 304 stainless steel, providing rugged, outdoor-ready protection that aligns with common solar industry standards and code requirements.
The non-fusible, grounded design with isolated return reduces fault propagation and simplifies troubleshooting, translating to less downtime and faster service. The 304 stainless steel NEMA 4X enclosure resists corrosion, lowering maintenance costs over the system life. Eaton’s warranty policy further supports long-term reliability for solar deployments.
The unit accommodates a substantial footprint: length 57.47 in, width 24.12 in, height 12.43 in, with a 60 lb weight. Plan for outdoor mounting in a protected area, allowing for proper clearance around the enclosure for wiring, ventilation, and access to the main lugs (LC, SR, EG) for field terminations.
