60 A amperage rating and a single circuit configuration provide straightforward field wiring, improving safety by reducing potential fault paths and enabling efficient maintenance workflows on PV arrays. This translates to quicker string isolation during commissioning and routine checks, shortening project timelines while maintaining high reliability. The NEMA 4 enclosure with painted galvanized steel delivers outdoor durability, minimizing corrosion-related downtime and lowering enclosure maintenance costs for rooftop or ground-mounted installations. A 600 VDC rating supports high-voltage DC strings, expanding system design options and reducing the need for additional protective devices on smaller PV configurations. Lug compatibility for #14-#2 AWG and #14-1/0 AWG solid return simplifies wiring, cuts splicing needs, and accelerates field wiring. UL 98B and NEC 690 per UL 1741 certification ensure compliant, risk-mitigated PV system integration across commercial and industrial applications. Catalog notes remind users to consult dimension tables for available configurations, ensuring accurate selection for specific ampacity and circuit counts.

FAQs
Confirm that the DCU1062UPM is installed in a NEMA 4 weatherproof enclosure and that the lug sizing matches your conductors (#14-#2 AWG, #14-1/0 AWG solid return). Verify the single 60 A circuit configuration and that the system voltage does not exceed 600 VDC per pole. Reference the Eaton datasheet for dimension tables to ensure fitment in the planned enclosure footprint.
This unit carries UL 98B and NEC 690 per UL 1741 certifications, aligning with PV safety and performance requirements. Use in applications that demand certified isolation devices for ungrounded PV systems, and ensure installation complies with local electrical codes and utility interconnection standards.
Yes. The enclosure is NEMA 4 rated with painted galvanized steel, designed to withstand outdoor exposure and wet or dusty conditions typical of rooftop and outdoor PV installations, reducing corrosion-related maintenance and extending service life.
This device is specified as an ungrounded, non-fusible DC disconnect. It is intended for ungrounded solar applications where a simple, robust isolation device is required for PV strings, with appropriate protection upstream and in accordance with NEC 690 guidance.
The combination of a single 60 A circuit, durable NEMA 4 enclosure, and UL/NEC compliance reduces maintenance hours during commissioning and service checks. The straightforward wiring with standard lug sizes minimizes field labor, while the non-fusible design lowers replacement risk during fault events, contributing to faster ROI in commercial PV deployments.
