DCU3062FPM features a 60 A per circuit rating across three circuits, delivering a compact, scalable solution for mid-size solar arrays and reducing the number of standalone disconnects. This translates into faster installation, fewer components to manage, and more predictable wiring layouts for field technicians. For Ungrounded PV Systems the device provides safe switching without creating a grounded path, improving fault isolation and reducing arc risk during maintenance. In a NEMA 4 painted galvanized steel enclosure, it resists dust and water ingress, boosting uptime in outdoor or harsh indoor environments. The fusible fuse configuration enhances protection against overcurrent while meeting NEC 690 requirements and UL 1741 expectations. With main lug connections sized for #14-#2 AWG lugs and #14-1/0 AWG solid returns, installation is straightforward and supports future expansion. The unit weighs 40 lb and measures 25.5 in by 13.25 in by 9 in, making it a manageable addition to standard electrical racks. Eaton’s one-year warranty (or 18 months from shipment) provides service continuity and peace of mind, reducing lifecycle costs and support overhead for operators. These design elements collectively improve safety, regulatory compliance, and total cost of ownership while supporting scalable PV projects.

FAQs
When planning installation, accommodate three circuits at 60 A each within a NEMA 4, painted galvanized steel enclosure. Allow space for 25.5 in L, 13.25 in W, and 9 in H, and plan lug connections for #14-#2 AWG and solid returns up to #14-1/0 AWG. Ensure proper mounting in a location that meets outdoor or harsh indoor conditions and verify NEC 690 and UL 1741 compliance during the wiring and labeling steps.
The DCU3062FPM is designed for PV applications and explicitly supports NEC 690 requirements as cited by UL 1741, with fusible protection and ungrounded system operation. It also carries UL 98B certification for enclosure reliability. In practice, this means safer switching of DC PV circuits, verified interrupt ratings, and documented compliance that simplifies inspections and system acceptance in commercial solar deployments.
Yes, the DCU3062FPM is rated for 600 VDC per pole and provides 60 A per circuit across 3 circuits. Main lug capacity accepts #14-#2 AWG lugs with #14-1/0 AWG solid returns, enabling flexible wiring configurations and easier integration with common PV combiner boxes and disconnect assemblies in mid-size solar projects.
The unit measures 25.5 inches in length, 13.25 inches in width, and 9 inches in height, with an approximate weight of 40 pounds. It features a NEMA 4 enclosure made from painted galvanized steel, designed for outdoor and harsh indoor environments, and provides fusible protection with a heavy-duty switch type suited for PV applications.
Eaton offers a one-year warranty from installation or eighteen months from shipment, whichever occurs first. The return on investment comes from increased safety, reduced downtime, simplified compliance with NEC UL 1741, longer service intervals, and easier field maintenance due to robust construction and clear labeling in a durable NEMA 4 enclosure.
