Eaton DCG1105UPM DC Disconnect - UL Listed, NEMA 4
Part Number: DCG1105UPM
Quick Summary
DCG1105UPM DC Disconnect is a heavy-duty isolation switch designed for 1000 VDC solar photovoltaic (PV) systems. In busy PV projects, unprotected DC switching increases arc-flash risk, downtime, and maintenance complexity. UL Listed certification and a rugged NEMA 4 enclosure help ensure reliable outdoor operation, while painted galvanized steel delivers durable protection in harsh environments. This unit supports a grounded, isolated-return DC system with a single 400 A circuit, simplifying wiring and commissioning. By standardizing on a compliant disconnect, procurement gains predictable lead times, installers benefit from faster mounting, and owners enjoy improved safety, uptime, and regulatory alignment for PV installations.

FAQs
The DCG1105UPM is engineered for outdoor solar PV installations and other DC photovoltaic systems up to 1000 VDC. It provides safe isolation for a single 400 A circuit with a grounded, isolated-return configuration, making it ideal for utility-scale and commercial solar projects where reliable DC switching is essential.
Yes. The DCG1105UPM is rated for 1000 VDC, supports a single 400 A circuit, and uses an isolated-return, grounded configuration. This compatibility simplifies system designs that employ high-voltage PV strings while maintaining safe, code-compliant isolation during maintenance.
The unit features a 12.42 inch depth, 57.47 inch height, and 24.12 inch width, with an approximate weight of 60 lb. Plan for service clearances and mounting access in outdoor or indoor equipment spaces. The NEMA 4 enclosure supports outdoor placement without additional protection, reducing enclosure requirements.
The DCG1105UPM carries UL Listed certification, and it uses a NEMA 4 rated enclosure with a painted galvanized steel body. These standards support safe outdoor operation, reliability in harsh environments, and streamlined compliance during audits and inspections.
With non-fusible protection, grounded isolation, and a robust outdoor-rated enclosure, the DCG1105UPM reduces arcing risk, simplifies fault isolation, and minimizes downtime. Its single high-current circuit lowers equipment count, enabling faster installation, predictable maintenance cycles, and clearer lifecycle cost projections for PV projects.
