FAQs
Install the three-pole disconnect in a suitable electrical space, ensuring the In/Out terminals accommodate 300 kcmil-#6 conductors (LC and SR) and that the unit is mounted in the NEMA 3R enclosure to withstand the site environment. Connect the grounded and isolated-return wiring per the UL 1741 and NEC guidelines, verify 600 VDC maximum, and inspect the fusible protection arrangement before commissioning.
DCG3064FRM carries UL 98B and NEC 690 per UL 1741 credentials, confirming high-level safety and performance for DC disconnects in solar installations. The NEMA 3R enclosure rating further validates weather resistance for outdoor use. These certifications streamline compliance checks, reduce risk during inspections, and support reliable operation in utility-scale or commercial PV projects.
Yes. The main lug wiring supports In/Out(LC): 300 kcmil-#6 and In/Out(SR): 300 kcmil-#6, enabling direct termination of substantial PV conductors. This compatibility minimizes splices, improves reliability, and simplifies installation in high-current solar configurations, while maintaining a grounded, isolated-return arrangement for safe operation.
Key benefits include robust 200 A capacity, 600 VDC rating, and fusible protection for rapid fault isolation. The NEMA 3R weather-rated enclosure supports outdoor deployment, while UL 98B/NEC 690 compliance ensures regulatory alignment. Its grounded, isolated-return design reduces potential fault paths, and its three-pole configuration supports scalable PV strings, contributing to improved uptime and lower lifecycle costs.
Expect minimal maintenance beyond routine inspection of connections and enclosure seals. The fusible protection reduces risk of damage from overloads, while the rugged galvanized steel enclosure resists corrosion in harsh environments. The warranty provides coverage during early life, and the device’s compatibility with large conductors streamlines future PV system expansions, improving total cost of ownership.
