FAQs
The DCU1061UPM is designed for outdoor PV installations with a NEMA 4 enclosure and painted galvanized steel body, providing weather resistance and robust protection. Important considerations include ensuring proper mounting, adequate space for wiring, confirmation of the single 30A, 600 VDC circuit, and correct lug sizing (#14-#2 AWG, up to #14-1/0 AWG solid return). Also verify NEC 690 compliance per UL 1741 and UL 98B certification during panel integration.
Yes. The DCU1061UPM is rated for 600 VDC per pole and supports a 30A, single-circuit configuration. This makes it suitable for many solar PV applications, including string protection and utility-scale or commercial rooftop installations, while maintaining safe isolation and non-fusible protection as specified.
An ungrounded DC disconnect minimizes ground potential paths and reduces ground fault current during normal operation. This simplifies protection coordination with other DC devices, lowers the risk of ground loops, and simplifies startup checks. For maintenance, operators should follow standard PPE and lockout/tagout procedures while verifying proper lug connections and enclosure seals to maintain corrosion resistance in outdoor environments.
The DCU1061UPM carries UL 98B and NEC 690 per UL 1741, ensuring compliance with recognized safety and electrical standards for DC switching equipment in solar installations. It also uses a NEMA 4 enclosure, suitable for outdoor use in harsh weather. Together, these certifications streamline approvals and help meet project-specific regulatory requirements.
