FAQs
DCG6064UPM supports large feeder conductors with In/Out LC 300 kcmil to #6 and In/Out SR 300 kcmil to #6, enabling direct connection to common solar DC components like combiner boxes and inverters. Its six-pole, non-fusible design reduces the need for additional switching devices while maintaining safe isolation for 600 VDC systems.
Isolated return means the return path for the circuit is electrically separated, which minimizes parallel fault paths and helps isolate faults quickly. This reduces arc-flash risk and simplifies fault diagnosis during maintenance, making it particularly beneficial for utility-scale and commercial PV installations where reliability and safety are paramount.
Yes. The unit features a NEMA 4 enclosure with painted galvanized steel, designed to resist dust, rain, and temperature fluctuations. This makes it well-suited for outdoor solar deployments on rooftops or field installations where rugged protection and durability are required to maintain uptime.
The DCG6064UPM complies with UL 98B and NEC 690 per UL 1741, ensuring safety and regulatory alignment for DC PV applications. These certifications support safe installation, regular maintenance, and smoother inspections in commercial and industrial energy systems.
Eaton provides a one-year limited warranty from installation or 18 months from shipment, whichever occurs first. Routine maintenance typically involves inspection of terminations and enclosure integrity. Its robust enclosure, high amperage rating, and non-fusible design help reduce ongoing maintenance costs and downtime.
