Eaton DCG2105UWM Heavy Duty DC Disconnect - NEMA 4X

Feature → Business Impact → Application: The DCG2105UWM is a heavy duty DC disconnect rated at 400 A and 1000 VDC, enabling high-current isolation for solar PV systems with minimal voltage drop. This directly reduces service downtime and arc-flash exposure during maintenance, improving worker safety and compliance in outdoor installations. In practice, engineers can deploy the unit in rooftop arrays or utility-scale PV setups where space and durability are critical, while meeting strict safety standards. Feature → Durable enclosure: NEMA 4X rated, 304 stainless steel construction ensures corrosion and weather resistance; business impact is lower replacement costs and longer service intervals, particularly in coastal or harsh environments. Application: outdoor solar farms, desert rooftops, and marine-adjacent facilities benefit from extended lifespan and predictable performance. Feature → Grounded, non-fusible design: simplifies installation and simplifies fault isolation; reduces downstream fault propagation and simplifies maintenance procedures. Application: solar battery banks and PV inverters in commercial installations. Feature → Two circuits and robust compatibility: supports multi-string DC configurations with straightforward wiring and service access; improves system modularity and scalability. Application: campus or multi-string solar arrays. Feature → UL Listed and wide voltage rating: ensures regulatory compliance and supplier confidence for procurement and integration with other protection devices. Application: project approvals, electrical room planning, and cross-vendor compatibility. Feature → Stainless steel enclosure with clear labeling: aids field installation and reduces mis-wiring risk, while enabling clean routing of conductors. Application: outdoor enclosures near inverters, combiner boxes, and DC disconnect stations. Feature → Easy integration with existing protection schemes: supports standard DIN rail or panel mounting practices in large electrical rooms. Application: retrofits and new builds where space optimization is critical. This combination of features delivers measurable outcomes, including safer work practices, reduced maintenance costs, and improved system uptime across solar installations.
