FAQs
For installation, mount the DCU1062URM in a NEMA 3R rated enclosure suitable for outdoor or damp locations. Plan for one 60 A circuit, use conductors sized #14-#2 AWG for lugs with a solid return up to #14-1/0 AWG, and ensure wire routing maintains clearances per UL 98B and NEC 690 requirements. The device is non-fusible and designed for ungrouded PV systems, simplifying the isolation point at the PV side.
Yes. The DCU1062URM is certified to UL 98B with NEC 690 referenced per UL 1741. This ensures it meets required safety and performance criteria for solar PV installations, including non-fusible protection and ungrouned system applications. Compliance supports safer field installations and smoother regulatory audits.
The unit supports a single circuit rated at 60 A with a maximum of 600 VDC per pole, suitable for ungrounded PV configurations. It accepts lug ranges from #14-#2 AWG and solid returns up to #14-1/0 AWG, making it adaptable to common solar array wiring schemes and enabling straightforward integration into existing PV layouts.
The device provides a robust, non-fusible disconnect with a NEMA 3R enclosure, enabling quick and reliable isolation of the DC side. This reduces arc exposure, simplifies maintenance shutdowns, and lowers risk during servicing. The rugged galvanized steel housing resists environmental wear, supporting long-term reliability with minimal upkeep.
Consider the 60 A, 1 circuit, 600 VDC per pole rating, ungrounded configuration, and NEMA 3R enclosure to suit outdoor PV deployments. Verify conductor compatibility (#14-#2 AWG lug capacity; #14-1/0 AWG return), required warranty terms, and alignment with UL 98B/NEC 690 per UL 1741. Confirm dimensions and mounting clearances for your enclosure design and site constraints.
