Eaton DCG4064FXM DC Disconnect - NEMA 4X and 600 VDC
Part Number: DCG4064FXM
Quick Summary
DC Disconnects provide safe isolation for solar DC circuits, and the Eaton DCG4064FXM delivers reliable 200 A isolation in four-pole configurations. Maintenance and downtime for PV arrays can be costly, but this unit's rugged 316 stainless steel enclosure and NEMA 4X rating withstand outdoor exposure, simplifying outdoor installations. It carries UL 98B and NEC 690 per UL 1741 compliance, reinforcing safety and code alignment for solar projects. Grounded, fusible protection plus isolated return support safe operation and robust fault response. For procurement teams, the four-pole arrangement, large main lug connections (LC and SR), and standardized form factor streamline wiring, commissioning, and service, delivering predictable performance, reduced maintenance, and a lower total cost of ownership.

FAQs
Plan for a four-pole DC disconnect with fusible protection to ensure full isolation of each string. Verify LC and SR lug sizes (300 kcmil-#6) for feed connections, ensure a grounded, isolated return configuration, and confirm compliance with UL 98B and NEC 690 per UL 1741. Install the 316 stainless steel, NEMA 4X enclosure in outdoor environments with appropriate mounting and clearances.
Yes. The unit is rated for 600 VDC per pole and 200 A continuous operation. It uses large lug connections for both LC and SR paths, specified as 300 kcmil-#6, supporting high-current solar feeder runs with reduced termination points and improved reliability.
The DCG4064FXM carries UL 98B and NEC 690 per UL 1741 accreditation, with a NEMA 4X enclosure. These certifications align the product with common safety and solar installation standards, facilitating permitting and inspection processes for PV projects.
The rugged 316 stainless steel enclosure and NEMA 4X rating resist corrosion in outdoor settings, reducing enclosure maintenance. Fusible protection and isolated return enhance safety, lowering fault-related downtime. Large lug connections simplify wiring and reduce field splices, lowering labor costs and delivering a favorable total cost of ownership over the project lifespan.
Outdoor exposure, corrosion, and complex wiring are common challenges in PV projects. This model’s durable enclosure, full four-pole isolation, and large LC/SR lugs simplify outdoor installs, improve fault clarity, and support fast commissioning, while UL and NEC compliance provide confidence during inspections and ongoing regulatory adherence.
