FAQs
Yes. DCU2102UXM is designed for 60 A operation and features lug capacity for #14-#2 AWG conductors with a solid return. This makes field wiring straightforward for common PV string configurations, reducing cabling complexity and ensuring robust connections across two circuits. Always verify your specific conductor insulation and torque requirements per Eaton installation guidelines.
DCU2102UXM provides a 1000 VDC system rating, non-fusible protection, and an ungrounded configuration with two circuits. The enclosure is NEMA 4X and constructed from 316 stainless steel, delivering corrosion resistance and weather sealing suitable for outdoor solar installations. These specs support safe isolation, reliable operation, and compliance with high-voltage PV standards.
Absolutely. The NEMA 4X enclosure and 316 stainless steel construction are specifically selected for moisture, dust, and wash-down resilience. This makes DCU2102UXM a suitable choice for outdoor solar sites, rooftop arrays, and exposed equipment rooms where environmental protection and long-term durability are essential.
The unit complies with NEC 690 requirements as referenced by UL 1741, and it carries UL 98B ratings for motor or protective-switching equipment. This combination ensures high-voltage PV circuit protection meets established safety standards, supporting safe installation, maintenance, and regulatory alignment for solar projects.
Since the DCU2102UXM is non-fusible, routine maintenance focuses on connection integrity and enclosure condition rather than fuse replacements. The 316 stainless steel, corrosion-resistant enclosure reduces environmental wear. Plan periodic torque checks on lugs, inspect for moisture ingress, and reference Eaton’s warranty policy (one year from installation or 18 months from shipment) to manage lifecycle costs.
