Feature → Business Impact → Application: The DCG3065UPM is a three-pole, non-fusible DC disconnect rated for 400 A, offering isolated return and a clear, safe path to de-energize solar arrays. This enables rapid fault isolation and reduces the risk of arc flash during maintenance, directly impacting on-site safety and uptime in solar farms and rooftop PV systems. Application: ideal for solar PV installations requiring reliable DC isolation with straightforward maintenance. Feature → Business Impact → Application: The enclosure is a painted galvanized steel NEMA 4 housing, delivering weather resistance and durability in outdoor environments. This reduces corrosion-related downtime and extends service life in harsh climates, ensuring consistent performance across exposure conditions. Application: outdoor PV installations, rooftop arrays, and exposed electrical rooms. Feature → Business Impact → Application: Main lug wiring accommodates large conductors in LC and SR configurations (In/Out(LC): (1) 750 MCM-1/0 and (1) 600 MCM-#2; In/Out(SR): (2) 750 MCM-1/0), supporting high current with fewer terminations and streamlined installation. This translates to faster assembly, lower labor costs, and improved reliability for 400 A circuits. Application: PV combiner boxes, DC combiner sections, and PV string infeed points. Feature → Business Impact → Application: UL Listing provides regulatory confidence and market readiness, while the NEMA 4 protection ensures compliance with outdoor installation standards. This combination reduces qualification time for projects and accelerates procurement cycles. Application: commercial and utility-scale solar projects seeking proven, standards-compliant protection solutions. Feature → Business Impact → Application: The product’s warranty policy (one year from installation or eighteen months from shipment) offers predictable support and risk mitigation for procurement and maintenance planning. Application: project rollouts, service contracts, and long-term asset management for solar DC protection devices.

FAQs
DCG3065UPM is a three-pole, non-fusible DC disconnect rated at 400 A with In/Out LC wiring of (1) 750 MCM-1/0 and (1) 600 MCM-#2, plus In/Out SR wiring of (2) 750 MCM-1/0. This design accommodates high-current PV strings and large conductor sizes, simplifying installations and reducing termination points while maintaining a robust 600 VDC system.
For outdoor PV deployments, ensure proper mounting access for maintenance, secure enclosure sealing against weather ingress, and correct clearance for wiring. The DCG3065UPM uses a painted galvanized steel NEMA 4 enclosure, so placement should protect the opening mechanism from direct exposure to severe weather while allowing safe, code-compliant wiring to In/Out conductors.
The DCG3065UPM is a non-fusible, grounded, three-pole DC disconnect optimized for PV systems. Its isolation capability, UL Listed compliance, and large-conductor capacity help minimize fault propagation and simplify maintenance, while the non-fusible design reduces nuisance tripping and offers straightforward integration with PV inverters and combiner boxes.
This product is UL Listed and housed in a NEMA 4 rated enclosure with painted galvanized steel. These standards support outdoor performance and electrical safety in solar installations, aligning with common regulatory requirements for outdoor DC protection devices and ensuring dependable operation in harsh environments.
The warranty follows Eaton's policy 25-000: one year from the date of installation or eighteen months from the date of shipment, whichever occurs first. This provides protection against manufacturing defects and helps with long-term maintenance budgeting for solar protection devices.
