FAQs

What should I know when installing DCG6064FRM in a solar PV layout? This unit requires a six-pole, fusible disconnect designed for 600 VDC systems. Ensure In/Out LC and SR conductors are prepared to 300 kcmil-#6, with proper grounding and isolated return. Verify enclosure clearances, securing the NEMA 3R rating for outdoor exposure and adherence to UL 98B and NEC 690 per UL 1741 requirements.
The DCG6064FRM is certified to UL 98B and NEC 690 per UL 1741, with a NEMA 3R enclosure. These certifications confirm safe operation, fire resistance, and code compliance for solar DC isolation in outdoor environments. They streamline permitting, ensure interoperability with other PV components, and support long-term reliability in industrial applications.
Yes. The unit supports main lugs sized for In/Out(LC) 300 kcmil-#6 and In/Out(SR) 300 kcmil-#6 conductors, enabling robust connections for large PV strings and DC distribution runs. Compatibility with these conductor sizes reduces the need for additional splices and simplifies the electrical design while meeting current rating and voltage requirements.
Absolutely. The DCG6064FRM’s NEMA 3R enclosure, painted galvanized steel construction, grounded system with isolated return, and 600 VDC rating make it well-suited for outdoor grid-tied PV installations. Its fusible protection and six-pole design support safe strategic isolation, electrical code compliance, and reliable operation in grid-connected solar projects.
Eaton offers a one-year warranty from installation or eighteen months from shipment, whichever occurs first (policy 25-000). Routine maintenance is typically focused on ensuring enclosure integrity, verifying conductor connections, and confirming fuse status. The robust NEMA 3R enclosure and UL-listed components help minimize downtime and simplify spare-part planning.
