FAQs
Install the DCU1061FPM as a single-circuit, ungrounded DC disconnect in the PV array DC side. Mount per NEMA 4 outdoor guidelines, connect conductors with lug sizes from #14 to #2 AWG and solid returns up to #14-1/0 AWG, and wire the fusible protection path in series with the PV source. Follow NEC 690 for clearances and labeling.
Its painted galvanized steel enclosure provides NEMA 4 weatherproof protection, safeguarding the switch from rain, dust, and corrosion. With a 600 VDC maximum and 30 A rating for a single circuit, it supports typical solar string configurations, while the ungrounded design reduces ground fault risk. The rugged build ensures long-term reliability on rooftops or outdoor sites.
The DCU1061FPM is designed to meet NEC 690 requirements via UL 1741 recognition and UL 98B enclosure certification. These certifications validate safe PV isolation, proper fusible protection, and enclosure integrity, helping you stay compliant with utility interconnection and safety standards. The configuration also supports straightforward inspections and maintenance without compromising safety.
Yes. The main lug capacity accommodates #14-#2 AWG conductors for the circuit and up to #14-1/0 AWG for solid returns, offering flexibility for various PV string configurations and future expansions. This reduces mid-project rewiring and supports robust, code-compliant terminations in outdoor PV installations.
The product carries Eaton's warranty policy: one year from installation or eighteen months from shipment, whichever occurs first. Routine inspection of fusible links and enclosure integrity is straightforward due to the accessible design. Proper maintenance ensures reliable PV isolation and minimizes unscheduled downtime, protecting total cost of ownership in solar projects.
