Eaton DCG3064UPM DC Disconnect - NEMA 4, 600VDC
Part Number: DCG3064UPM
Quick Summary
The Eaton DCG3064UPM DC disconnect provides rugged, field-installable DC power isolation for solar PV systems. In practice, engineers contend with outdoor exposure, large conductor sizes, and the need for reliable protection that minimizes downtime. This unit meets UL 98B and NEC 690 per UL 1741 requirements and wears a NEMA 4 enclosure, giving weather resistance and regulatory confidence. With a 200 A rating, 600 VDC per pole, and three poles, it handles demanding PV arrays while maintaining a grounded, isolated return. Designed for solar installations, it supports large lugs (300 kcmil-#6) and is compatible with common mounting and wiring practices, delivering safe, scalable protection with reduced maintenance costs.

Feature: 200 A, three-pole, 600 VDC rating. With these capabilities, the DCG3064UPM supports high-current PV strings and centralizes isolation, reducing the number of devices and simplifying fault clearance in solar DC distribution. Feature: NEMA 4 painted galvanized steel enclosure. Outdoor-rated housing delivers weatherproof protection that lowers weather-related downtime and maintenance costs for rooftop and ground-mounted installations. Feature: Non-fusible with isolated return and grounded configuration. This design minimizes arc-flash risk and streamlines fault isolation during service, improving safety and regulatory alignment. Feature: Large conductor compatibility. Main lug connections accept up to 300 kcmil-#6 (LC) and 300 kcmil-#6 (SR), reducing connector complexity and installation time while supporting long feeders with low resistance. Feature: Three-pole DC PV application with single-throw operation. The simple, robust switch arrangement suits frequent on/off control in PV inverters and DC distribution cabinets. Feature: Certifications and application fit. UL 98B and NEC 690 per UL 1741 compliance ensure critical solar protection standards are met, while the isolated return and grounded system support typical rooftop and utility-scale PV configurations.

FAQs
Install the unit on a level, code-compliant mounting surface with the enclosure oriented for easy access and clearances around the NEMA 4 housing. Ensure proper environmental protection and wiring routes that keep conductors within the LC and SR lug specified ranges (up to 300 kcmil-#6). Use appropriate hardware and follow local electrical codes for outdoor PV deployments.
Match a 200 A amperage rating, a 600 VDC maximum system voltage per pole, and three-pole configuration. Use In/Out LC and SR lugs rated at 300 kcmil-#6, ensure grounded, isolated return, and select non-fusible protection as specified for DC photovoltaic applications.
Yes. The NEMA 4 enclosure provides weather resistance for outdoor use, and the 600 VDC rating supports common rooftop and ground-mounted PV configurations. Its three-pole, non-fusible design is well-suited for isolating DC circuits in various PV system layouts.
The DCG3064UPM carries UL 98B and NEC 690 per UL 1741 certifications, with a NEMA 4 enclosure rating. These align with regulatory requirements for solar DC protection and outdoor service conditions.
Warranty terms follow Eaton policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first. Routine maintenance includes visual inspection, torque verification of lugs, and periodic cleaning of the enclosure to maintain corrosion resistance in outdoor environments.
