Feature: 200 A amperage rating enables you to safely interrupt full PV array current without oversizing components. Benefit: Improves system reliability and reduces the need for frequent panelboard upgrades, translating to lower lifecycle costs for commercial and utility-scale solar deployments. Application: Suitable for solar DC disconnects in rooftop and ground-mmount PV systems where high current handling is required. Feature: 600 VDC maximum voltage and four-pole design. Benefit: Provides robust isolation with a grounded return path, enhancing safety margins and simplifying compliance with utility interconnection standards. Application: Ideal for centralized DC switching in PV farms and battery storage projects. Feature: Non-fusible protection and isolated return. Benefit: Reduces maintenance complexity and allows straightforward fault visibility, while keeping the wiring topology clean and serviceable. Application: Preferred in PV PV+storage configurations where rapid maintenance is critical. Feature: NEMA 4 enclosure with painted galvanized steel. Benefit: Delivers weather resistance and corrosion protection for outdoor installations, minimizing downtime from dust, water, and temperature exposure. Application: Outdoor solar installations and harsh environments where reliable enclosure integrity matters. Feature: Large lug wires (In/Out LC: 300 kcmil-#6, In/Out SR: 300 kcmil-#6). Benefit: Supports heavy conductor runs with secure terminations, enabling efficient field wiring and reducing termination hassles. Application: Aligns with utility-grade photovoltaic system wiring practices. Feature: 4 poles, grounded, four-puse configuration. Benefit: Provides isolated return and independent switching per pole, improving fault isolation and safety during commissioning and maintenance. Application: Four-pole DC disconnects are standard for PV array isolation in multi-string configurations. Feature: Certifications NEC 690 per UL 1741 and UL 98B. Benefit: Ensures compliance with solar installation codes and electrical safety standards, reducing regulatory risk. Application: Essential for code-compliant PV installations and utility-grade interconnections.

FAQs
The DCG4064UPM is rated for 200 A and a maximum of 600 VDC. It supports four poles with main lug wire sizes of In/Out(LC) 300 kcmil-#6 and In/Out(SR) 300 kcmil-#6, enabling large conductor runs for PV arrays.
Yes. It uses a NEMA 4 enclosure with painted galvanized steel, designed to withstand outdoor, dusty, and wet environments, providing reliable protection for PV DC isolation in exposed locations.
The unit is specified for NEC 690 compliance and UL 1741 (with UL 98B) certifications, ensuring safe operation, appropriate overcurrent protection pathways, and code-aligned PV isolation for solar installations.
Consider four-pole isolation, grounded return configuration, and ample clearance for large conductors (up to 300 kcmil-#6). Plan for outdoor mounting in a NEMA 4 enclosure, and verify compatibility with In/Out LC and SR lug configurations to minimize wiring errors.
The unit carries Eaton's standard warranty policy (one year from installation or 18 months from shipment, whichever occurs first). Non-fusible protection simplifies maintenance by avoiding fuse replacements, reduces fault-tripping risk, and can lower total cost of ownership in PV installations.
