Three circuits rated at 30A each, with a 600 VDC maximum, deliver safe, scalable isolation for PV strings, reducing fault propagation and arc-flash risk while helping meet NEC/UL requirements in outdoor solar arrays. The NEMA 3R enclosure, crafted from painted galvanized steel, delivers outdoor durability against rain, hail, and temperature cycling, minimizing corrosion and maintenance costs in rooftop and ground-mounted installations. Lug compatibility includes main lug sizes of #14-#2 AWG and solid returns up to #14-1/0 AWG, streamlining wiring and reducing field modifications during installation and future upgrades. The product is part of Eaton’s DC Photovoltaic Applications series, aligning with industry standards for reliability, serviceability, and global solar deployments. A one-year warranty (or 18 months from shipment) provides peace of mind and supports consistent uptime in mission-critical PV controls. Dimensions of 25.5 in length, 13.25 in width, and 9 in height enable practical placement in standard electrical spaces while accommodating three separate circuits.

FAQs
The DCU3061FRM is designed for ungrounded solar PV systems with three independent circuits, each rated at 30A, and it accepts lug configurations of #14-#2 AWG per circuit with solid returns up to #14-1/0 AWG. For wiring, plan for 600 VDC per pole, follow NEC guidelines, and use the fusible protection model to ensure rapid isolation during maintenance or fault conditions. In rooftop or utility-scale PV installations, this unit simplifies output string isolation while maintaining compliance with UL 690 and UL 1741 requirements.
The DCU3061FRM combines three 30A circuits with a 600 VDC rating and fusible protection, specifically addressing solar PV needs for safe isolation and rapid shutdown procedures. Its NEMA 3R enclosure provides weather resistance for outdoor deployments, and its compatibility with common PV wiring sizes reduces field wiring complexity. This makes it well-suited for rooftop arrays and utility-scale solar installations seeking reliable isolation and long-term performance.
This unit adheres to NEC 690 requirements as specified by UL 1741, with UL 98B protection for disconnect enclosures. These certifications ensure safe operation in outdoor solar installations and align with industry safety expectations. Customers can rely on compliance for code-based installations, commissioning, and ongoing maintenance of PV systems.
Dimensions are 25.5 inches in length, 13.25 inches in width, and 9 inches in height, with a weight of approximately 40 pounds. Its NEMA 3R enclosure supports outdoor mounting on standard electrical chases or walls, and the unit’s form factor allows for straightforward installation alongside other DC protection devices. Plan for ventilation and clearance to ensure access for wiring and maintenance.
Beyond basic safety and compliance, the DCU3061FRM offers predictable maintenance costs due to its rugged galvanized steel enclosure and straightforward wiring. The part’s three-circuit configuration supports scalable PV layouts, reducing the need for future replacements during capacity expansion. The warranty (one year from installation or 18 months from shipment) provides protection against manufacturing defects, contributing to a favorable return on investment for rooftop and utility-scale PV deployments.
