Eaton DCG2104FWM heavy-duty DC Disconnect - NEMA 4X 1000V

This DC disconnect delivers 200 A across two circuits with fusible protection and a grounded configuration, enabling quick, safe isolation of solar arrays. The product design supports LC, SR, and EG main lug wiring, accommodating a wide conductor range and simplifying field assembly. In practice, this translates to faster commissioning, reduced wiring errors, and clearly defined protection paths that meet project-specific fusing requirements and code expectations. Built for outdoor, harsh environments, the 304 stainless steel enclosure carries a NEMA 4X rating and a robust gasketed seal to resist dust, moisture, and washdowns. The isolated return feature minimizes feedback into control wiring and reduces the risk of unwanted currents on the DC side, improving reliability in utility-scale and commercial PV installations. These characteristics also enable straightforward retrofits where space and accessibility are constrained. Certified to UL 98B and NEC 690 per UL 1741, the device supports critical compliance needs for utilities and developers, while the 1000 VDC system voltage rating aligns with modern PV architectures. The combination of rugged enclosure and high-current capability makes it a practical fit for mid- to large-size solar projects, reducing risk during fault events and facilitating inspection-ready documentation. From an installation perspective, the DCG2104FWM’s dimensions (57.47 in long, 24.12 in wide, 12.43 in tall) and 60 lb weight enable stable mounting on standard equipment pads or enclosures. The warranty coverage (one year from installation or 18 months from shipment) provides a concrete risk-mitigation cushion, while Eaton’s support ecosystem helps with spare parts and technical guidance during commissioning and maintenance. Installers benefit from proven compatibility with the LC, SR, and EG lug configurations, enabling quick sourcing of compatible cables and reducing inventory complexity. The fusion of rugged enclosure, isolation capability, and codified protection supports lifecycle cost control by minimizing rework, improving preventive maintenance planning, and accelerating regulatory approvals in PV projects.
