The DCU1101UXM uses a 316 stainless steel, NEMA 4X enclosure that resists corrosion, enabling reliable outdoor performance and reduced maintenance in solar installations. Feature → Business Impact → Application: Durable enclosure extends service life and lowers lifecycle costs for exposed PV sites, making it ideal for rooftop and ground-mounted arrays. The 30 A, 1000 VDC rating with a non-fusible, ungrounded design provides safe DC switching while simplifying integration with standard PV conductors; Application: DC isolation points in solar arrays, with measurable gains in safety and uptime. The unit supports #14-#2 AWG lug capacity for both lug and solid return wiring, enabling straightforward field wiring and scalable system layouts; Application: Easy, code-compliant wiring in commercial PV projects. With a single circuit, ungrounded configuration reduces wiring complexity and surge paths; Application: Compact DC distribution in string-level or microgrid configurations. Dimensions (10.22 in depth, 8.76 in width, 14.14 in height) and a 21 lb weight make it a practical fit for constrained electrical rooms and outdoor enclosures. Warranty is Eaton’s 25-000 policy (1 year from installation or 18 months from shipment), supporting uptime expectations and service planning. Certifications and standards (UL 98B, NEC 690 per UL 1741) reinforce compliance and risk management for regulated solar markets.
