Eaton DCG1154UWM-000W DC Disconnect - UL Listed
Part Number: DCG1154UWM-000W
Quick Summary
Eaton heavy duty DC disconnect is designed to safely isolate 1500 VDC circuits in industrial power systems. Engineers often struggle with reliable DC isolation while minimizing arc-flash risk and unplanned downtime. This device leverages a non-fusible, single-circuit design with a 200 A rating and a 1500 VDC capability to deliver predictable, fail-safe operation in harsh environments. UL Listed certification supports regulatory compliance, while a NEMA 4X stainless steel enclosure provides corrosion resistance and washdown compatibility. The compact form and upper window enable straightforward installation and status monitoring, reducing maintenance cycles. For procurement and field service, this solution aligns with safety standards and supports scalable DC distribution in solar, storage, and industrial applications.

FAQs
The DCG1154UWM-000W is a single-circuit, 200 A, 1500 VDC disconnect designed for DC ground systems and can retrofit into standard layouts that accept mid-size disconnects. Its 16.95 in width, 35.38 in height, and 7.27 in depth provide a predictable footprint, while the NEMA 4X enclosure supports rugged mounting in both indoor and outdoor installations.
Key safety features include a non-fusible construction that minimizes arc-fault risk during switching, a DC ground configuration for safe potential referencing, and UL Listed certification to ensure compliance with electrical safety standards. The upper window enables quick visual status assessment, reducing on-site switching mistakes during maintenance.
Yes. With a 1500 VDC rating and 200 A capacity in a single circuit, this disconnect is well-suited for solar PV arrays, energy storage systems, and other high-voltage DC distribution scenarios. Its stainless steel, washdown-ready enclosure makes it resilient in outdoor or dusty environments, aligning with typical solar and storage infrastructure requirements.
Installers should ensure proper mounting clearances and secure terminal connections per Eaton guidelines. The 304 stainless steel enclosure provides corrosion resistance and weathering protection, so position the unit to minimize exposure to direct impact while maintaining access for inspection through the upper status window.
Non-fusible disconnects require less fuse maintenance, but periodic inspection of terminal connections, enclosure integrity, and the status window is advised. Since the unit is UL Listed and built in a durable NEMA 4X enclosure, routine checks focus on mounting security, insulation condition, and any signs of corrosion or contamination in harsh environments.
