Eaton DCG3063URM DC Disconnect - NEMA 3R
Part Number: DCG3063URM
Quick Summary
Eaton DCG3063URM DC Disconnect provides rugged, safe isolation for DC circuits in solar PV installations. A common challenge is selecting a disconnect that withstands outdoor exposure, meets code, and doesn’t complicate maintenance. This unit aligns with NEC 690 per UL 1741 and UL 98B, and it uses a NEMA 3R painted galvanized enclosure to perform reliably outside. For installers and procurement teams, the 100 A rating, three circuits, and 600 VDC per pole translate into fewer components and faster commissioning. The design supports grounded PV systems with straightforward wiring, delivering robust protection with practical installation advantages and long-term reliability.

Selling Policy 25-000 - Distribution and Control Products and Services
Feature → Business Impact → Application: 100 A amperage rating provides solid headroom for typical residential and commercial PV strings, reducing the need for additional protection devices and enabling streamlined design. This translates to lower material costs and faster project timelines when wiring a three-pole, non-fusible DC disconnect in outdoor PV installations. Feature → Business Impact → Application: Non-fusible protection simplifies maintenance schedules and improves reliability in continuous-duty solar environments, minimizing fault-tripping risk while maintaining swift isolation during servicing. Feature → Business Impact → Application: NEMA 3R enclosure in painted galvanized steel delivers outdoor durability, corrosion resistance, and rain-sleet exposure protection, supporting rooftop and ground-mounted installations with less enclosure-related downtime. Feature → Business Impact → Application: In/Out wiring capability (1/0-#14 AWG input) enables flexible field configurations and compatibility with common PV cables, reducing time on the rack and permitting faster commissioning. Feature → Business Impact → Application: 600 VDC per pole with three-pole operation ensures compatible isolation for multi-string solar arrays, improving system safety and compliance with NEC 690 requirements. Feature → Business Impact → Application: Grounded system design and grounded isolation support safer fault handling and clearer current paths, aiding preventive maintenance and easier troubleshooting. Feature → Business Impact → Application: Compatibility with 3 circuits and a 600 VDC rating supports scalable solar installations, allowing phased expansion without replacing the disconnect. The result is improved efficiency, safer operations, and measurable cost savings over the system lifecycle.
