The DCG2064UPM is a two-pole, 200 A DC disconnect rated for 600 VDC, delivering reliable DC isolation for solar PV strings. This configuration helps meet NEC 690 and UL 1741 requirements while reducing fault propagation during maintenance and commissioning. It’s ideal for rooftop and ground-mounted solar installations that demand a durable, code-compliant DC disconnect switch for safe, uninterrupted operation. With a non-fusible design and an isolated-return configuration, the unit minimizes arc flash risk and simplifies troubleshooting by clearly separating the monitored path. This strengthens safety programs and reduces field repair time, especially in dense PV layouts where quick isolation matters. Use this in solar arrays where isolation integrity is essential. Encased in a NEMA 4, painted galvanized steel enclosure, the unit withstands rain, dust, and harsh environments while maintaining accessibility for routine maintenance. Outdoor-ready protection translates to longer service life and lower total cost of ownership for solar projects. Pair it with outdoor-rated wiring methods to maximize reliability in exposed installations. Rated for 2 circuits and with main lugs sized to 300 kcmil-#6, the DCG2064UPM accommodates large-diameter conductors without excessive splicing. The result is reduced installation time, lower voltage drop, and fewer termination points to fail. This is particularly advantageous for utility-scale solar feeders or high-current PV strings. UL 98B and NEC 690 per UL 1741 certifications validate compliance with North American safety standards, easing inspection and procurement. The NEMA 4 enclosure and grounded design further support safe outdoor operation and metadata traceability on projects. This certification combination provides confidence for engineering teams and project owners alike. Warranty coverage through Eaton’s policy adds a predictable maintenance horizon, while the unit’s compact footprint fits typical electrical rooms and outdoor enclosures. The 45 lb weight supports easier handling during installation and retrofit projects, helping teams meet tight schedules without compromising safety.

FAQs
Start by reviewing the Eaton specification sheet to confirm 200 A capacity and LC/SR termination options for 300 kcmil-#6 conductors. Mount the unit in a suitable enclosure, ensure proper grounding, and route conductors per NEC 690. Lockout/tagout during installation, verify a two-pole isolation, and test continuity and insulation resistance after wiring. This approach minimizes downtime and maintains compliance with UL 98B.
DCG2064UPM is a two-pole, non-fusible DC disconnect rated for 200 A and up to 600 VDC. It uses isolated return, supports 300 kcmil-#6 conductors, and provides NEMA 4 enclosure protection. The unit is designed for solar PV applications with UL 98B and NEC 690 per UL 1741 compliance, making it suitable for both rooftop and ground-mounted systems.
Yes. The product features a NEMA 4 painted galvanized steel enclosure, grounded configuration, and an outdoor-rated design that resists rain, dust, and harsh environments. It supports large conductors and reliable DC isolation, which is essential for safe rooftop PV commissioning, maintenance, and long-term reliability in exposed zones.
The device complies with UL 98B for electrical controls, NEC 690 considerations for solar installations, and UL 1741 as referenced in NEC 690. The enclosure is NEMA 4 rated for weather resistance, and the system uses an isolated return for safer operation. This certification set facilitates inspections and project approvals in North America.
Eaton provides a one-year warranty from installation or 18 months from shipment, whichever occurs first. The robust, non-fusible design reduces downtime and maintenance complexity, while the heavy-duty enclosure minimizes weather-related failures. For procurement, the 45 lb unit is manageable for field teams, and the 300 kcmil-#6 terminations support durable, long-life solar DC feeds.
