Eaton DCG1154FWM-000W DC Disconnect - 1500 VDC UL Listed
Part Number: DCG1154FWM-000W
Quick Summary
Eaton heavy duty DC disconnect is a safety-rated switch that provides isolated, lockable DC power paths for 1500 VDC systems in industrial automation. Maintenance teams often grapple with bulky enclosures and fuse modules that slow downtime and complicate regulatory compliance. UL Listed, NEMA 4X enclosure, and 304 stainless steel construction deliver corrosion resistance and reliable performance in washdown and dusty environments. This model supports 1500 VDC systems with 200 A capacity in a single-circuit configuration, making it ideal for solar, energy storage, and machine control. By consolidating switch, fuse, and enclosure into one rugged unit, OEMs reduce spare parts, shorten installation times, and improve safety discipline.

200 A amperage rating provides direct switchability for high-current DC feeders, eliminating the need for a separate current-limiting device. Business impact: fewer components, faster commissioning, and reduced risk during maintenance. Application: renewable energy systems, large DC drives, and storage solutions where a single, fusible disconnect must interrupt full line current while meeting safety standards. This rating also supports safe de-energization during wiring, testing, and preventive maintenance without compromising system uptime. Feature: 1500 VDC voltage rating supports modern high-voltage DC networks without compromising safety margins or insulation performance. Business impact: expands application scope to solar farms, battery energy storage, and data-center power systems that demand robust isolation. Application: single-circuit fusible DC disconnects used to isolate primary DC feeds for service or fault clearing, with fast fuse response and clear visibility. Feature: NEMA 4X enclosure and 304 stainless steel construction provide weatherproof, corrosion-resistant protection in harsh environments. Business impact: up-time in washdown areas, chemical plants, and outdoor installations where rust and moisture are ongoing concerns. Application: industrial automation and process industries requiring durable protection for switching devices. The enclosure design also supports easy cleaning and long service life under heavy use. Feature: Fusible protection integrates the protective element within the disconnect, enabling fast fault isolation and reduced arc energy. Business impact: improved safety, easier compliance with arc-flash guidelines, and simplified spare parts management. Application: critical DC circuits in energy storage systems, PV inverters, and heavy machinery that benefit from quick fuse changes and reduced downtime. Feature: Upper viewing window and 1-circuit layout simplify status checks, diagnostics, and service procedures. Business impact: faster fault identification, lower labor costs, and safer maintenance practices. Application: field service of DC protection and quick fuse replacement in industrial automation environments, with improved readiness for routine inspections.

FAQs
Install in a clean, accessible location with proper clearances per OSHA and NEC guidelines. The unit is UL Listed, NEMA 4X rated, and measures 7.27 in depth, 16.95 in width, and 35.38 in height, designed for 200 A at 1500 VDC. Use the upper window for fuse status checks, ensure proper grounding, and coordinate with any DC ground requirements. Plan for spare fuse parts and ensure pedestals or panels can support the enclosure weight.
Best suited for high-voltage DC networks such as solar energy systems, battery storage, and industrial automation where a single-circuit fusible disconnect is needed. It supports 1500 VDC and 200 A, enabling reliable isolation for PV inverters, energy storage banks, and heavy DC drives while maintaining safety and serviceability in rugged environments.
The DCG1154FWM-000W is UL Listed and housed in a NEMA 4X enclosure crafted from 304 stainless steel. This combination delivers weather resistance and corrosion protection suitable for washdown zones and outdoor installations. The design supports regulatory compliance audits and integrates easily with other Eaton protection devices in a distributed power system.
Fusible protection inside the disconnect limits fault current, reduces arc energy, and simplifies fault isolation without needing separate devices. This translates to improved safety, easier compliance with arc-flash guidelines, and streamlined spare parts management, especially in renewable energy and heavy equipment DC circuits where fast, reliable fuse changes are critical.
With a 7.27 in depth, 16.95 in width, and 35.38 in height footprint, the unit fits standard mounting envelopes while the upper viewing window enables quick fuse checks. A single 1-circuit configuration simplifies wiring and integration with existing DC protection schemes, accelerating commissioning and reducing the total cost of ownership in industrial automation or energy storage layouts.
