Feature: High current rating of 400 A and two-pole construction enable robust isolation for demanding solar arrays. This configuration ensures both poles switch together, preventing backfeed and reducing arc exposure during maintenance. Business Impact: Operators gain consistent, predictable performance even under heavy fault currents, lowering the risk of unscheduled downtime and safeguarding downstream equipment. Application: Ideal for DC photovoltaic circuits up to 600 V and large conductor runs, including In/Out(LC): (1) 750 MCM-1/0 and (1) 600 MCM-#2, as well as In/Out(SR): (2) 750 MCM-1/0. Feature: Fusible protection with an isolated return provides precise fault clearing and safer fault isolation. Business Impact: Improves overall system reliability by enabling controlled de-energization without disturbing neutral or grounding paths, which simplifies troubleshooting and reduces accidental energization. Application: Matches DC photovoltaic designs where selective protection and safe servicing are prioritized. Feature: NEMA 4X enclosure and 304 stainless steel construction deliver weather resistance and corrosion protection in outdoor environments. Business Impact: Extends service life in harsh environments, reducing replacement costs and downtime from weather-related deterioration. Application: Outdoor solar installations, marine-adjacent sites, or industrial facilities where washdowns or saline exposure are concerns. Feature: UL Listed and heavy-duty design supports code-compliant installations and faster approvals. Business Impact: Speeds installation and reduces permit delays by meeting recognized safety standards. Application: Industrial facilities, solar farms, and rooftop arrays in regulated sectors requiring certified protection. Feature: Flexible wiring configuration and practical installation advantages. In/Out wire sizing supports heavy conductors: In/Out(LC) (750 MCM-1/0 and 600 MCM-#2); In/Out(SR) (2) 750 MCM-1/0. Business Impact: Simplifies procurement and reduces field modification, speeding commissioning and minimizing errors. Application: DC PV installations that demand flexible lug arrangements and long-term reliability.

FAQs
Begin by selecting a suitable mounting location with access for service. Mount the unit in a weather-protected area, then connect the main lugs using the specified In/Out lug sizes: In/Out(LC) for 750 MCM-1/0 and 600 MCM-#2, and In/Out(SR) for 750 MCM-1/0. Ensure proper grounding and isolated return, install fuses per the protection type, and follow NEC/UL guidelines. After wiring, verify continuity, insulation resistance, and seal integrity of the NEMA 4X enclosure to ensure a safe, compliant installation.
It is rated for 400 A with a 600 VDC maximum voltage, two-pole design, and fusible protection with an isolated return, all of which support safe, reliable isolation and selective fault clearing in PV strings. UL Listed certification and a durable 304 stainless steel NEMA 4X enclosure further reinforce performance in outdoor environments, making it well suited for both utility-scale and commercial PV projects.
Yes. The enclosure is NEMA 4X rated and built from 304 stainless steel, providing excellent corrosion resistance and weather sealing for outdoor installations. The design supports routine maintenance, washdowns, and exposure to humidity or saline environments common in solar sites, while maintaining safe operation and easy access for fuse replacement and inspection.
The DCG2065FWM is UL Listed and features a NEMA 4X enclosure, confirming safety and weather protection for outdoor use. Complete installation guides and datasheets are available from Eaton, including conductor sizing and wiring diagrams for In/Out configurations. This certification package simplifies inspections, audits, and procurement for regulated facilities in need of certified solar isolation equipment.
By enabling rapid, safe isolation of PV circuits, the DCG2065FWM minimizes downtime during fault conditions and servicing. Its corrosion-resistant stainless steel enclosure reduces replacement costs, and fusible protection helps limit arc faults, contributing to lower maintenance and operating expenses over the system’s life.
