FAQs
The DCU3062UXM is rated for 60 A with three circuits, non-fusible and ungrounded, making it suitable for solar PV strings and similar DC installations. It supports #14-#2 AWG lugs and #14-1/0 AWG solid returns, enabling flexible wiring configurations and straightforward field wiring without oversized conductors. This compatibility helps engineers design scalable solar systems with reliable isolation at the point of interface.
It meets UL 98B and NEC 690 per UL 1741 requirements, ensuring recognized safety and performance in solar DC applications. The enclosure is NEMA 4X and the enclosure material is grade 316 stainless steel, providing outdoor durability and corrosion resistance essential for rooftop and ground-mounted installations.
Yes. With a 60 A, 3-circuit configuration, 600 VDC rating per pole, ungrounded design, and a rugged 316 stainless steel NEMA 4X enclosure, it is well-suited for both rooftop and utility-scale PV applications. Its non-fusible design simplifies protection schemes and allows easy integration into existing DC protection architectures.
Plan for a 10.22 in length, 12.88 in width, and 19.08 in height footprint with an approximate 37 lb weight to ensure proper mounting clearance. Ensure appropriate LOTO/lockout procedures and verify conductor sizes (#14-#2 AWG lug capacity, #14-1/0 AWG solid return). Confirm 600 VDC per pole rating in your PV string configuration and provide weatherproof routing for outdoor installation.
