Enclosure and material deliver durable outdoor protection: a NEMA 4X rating with 304 stainless steel construction reduces corrosion risk in harsh environments, enabling reliable outdoor installations and lower maintenance costs. This translates to longer service life and predictable performance in rooftop solar and industrial DC applications. The business impact is clear: fewer enclosure failures mean less downtime and lower lifecycle costs, especially in coastal or corrosive environments where corrosion can compromise safety and reliability. Application-wise, this is ideal for solar PV arrays exposed to weather, with installation confidence and extended field life as key advantages.

FAQs
The unit supports LC terminals for in/out 300 kcmil-#6, SR terminals for in/out 300 kcmil-#6, and EG terminals for in #4-#14 AWG and out 1/0-#14. This range enables flexible field wiring, reduces the need for splicing, and supports large PV conductors while maintaining a compact footprint.
The DCG1104UWM is rated for 200 A and a maximum of 1000 V DC. It is a single-circuit, grounded, non-fusible disconnect designed for DC photovoltaic systems, enabling straightforward protection without external fusing and simplifying maintenance plans.
Yes. It features a NEMA 4X rated enclosure with 304 stainless steel construction, designed to withstand moisture, dust, and corrosive environments typical of outdoor solar installations. Its corrosion resistance, along with UL 98B and NEC 690 per UL 1741 compliance, supports code‑conforming, durable outdoor use.
The unit carries UL 98B and NEC 690 per UL 1741 certifications, which validate electrical safety and solar-specific code compliance. These certifications help ensure regulatory alignment, reduce inspection risk, and support confident integration into commercial or utility-scale PV projects where standardization and safety are critical.
Eaton provides a one-year warranty from installation or eighteen months from shipment, whichever occurs first, per policy 25-000. Routine maintenance is minimized by the non-fusible, grounded design and robust corrosion-resistant enclosure, while the durable materials and UL/NEC compliance contribute to lower lifecycle costs and predictable uptime.
