Eaton DCG2103UWM Heavy Duty DC Disconnect - NEMA 4X

The DCG2103UWM combines a 100 A amperage rating with two circuits, enabling scalable DC isolation for mid to large solar PV installations. This arrangement supports multiple DC strings while keeping wiring organized and compliant with utility-grade safety practices. With field-ready lug capacity for #14-1/0 AWG and solid returns, installation time is reduced and connection reliability is improved. The non-fusible design simplifies maintenance and aligns with common DC safety practices in solar applications. Its NEMA 4X enclosure, crafted from 304 stainless steel, delivers proven outdoor durability against rain, dust, and impact. This corrosion resistance lowers maintenance frequency and extends service life in rooftop and ground-mount installations. The rugged enclosure protects sensitive switching devices while delivering predictable thermal and environmental performance. Customers benefit from fewer field demounts and easier compliance checks during commissioning and audits. Grounded, isolated return operation improves fault containment and reduces arc exposure during servicing. Rated for 1000 VDC system voltage, the unit supports high-voltage DC strings and longer run lengths common in solar projects. NEC 690 compliance and UL 1741/UL 98B alignment provide documented performance and safety assurances for utility-scale deployments. The product’s heavy-duty construction and clear documentation help avoid configuration errors in complex array topologies. Main lug capacity accommodates #14-1/0 AWG wiring for both lugs and solid returns, streamlining field wiring inventory. This compatibility simplifies supplier procurement and reduces on-site wire waste by matching common PV conductor sizes. The 2-circuit design supports modular expansion as PV capacity grows without requiring additional disconnects. Manufacturers and installers appreciate explicit dimension tables guiding exact configurations for project-specific amperage demands. Eaton backs the product with a clear warranty policy and robust support materials to minimize project risk. Certification coverage includes NEC/UL considerations, UL 98B enclosure fire ratings, and reliable corrosion resistance data. Shop-ready documentation, including the Eaton specification sheet, accelerates commissioning and reduces field questions. Together, these factors contribute to lower lifecycle costs, higher uptime, and stronger return on investment for solar deployments.
