FAQs
The DCG4064FPM should be mounted in a NEMA 4-rated enclosure or weather-protected location. Use the In/Out LC terminals for 300 kcmil-#6 conductors and SR terminals for the same gauge. Ensure proper clearances and follow cold-termination practices during wiring. Verify labeling and protective coordination with upstream devices and inverter input circuits.
This unit is rated for 200 A, four poles, and 600 VDC per pole. It features fusible protection, isolated return, and a four-pole design suitable for DC photovoltaic applications. Main feed connections are rated for In/Out(LC) and In/Out(SR) with 300 kcmil-#6, enabling robust current handling in solar arrays.
Yes. The enclosure is NEMA 4 rated and constructed from painted galvanized steel, providing outdoor protection against dust, water ingress, and corrosion. This makes it well-suited for rooftop and other outdoor PV installations where harsh weather conditions are common.
The DCG4064FPM carries UL 98B and NEC 690 per UL 1741 certifications, which support compliant solar DC isolation. The combination ensures safe operation, proper labeling, and conformity with industry safety codes relevant to utility-scale and commercial PV systems.
With fusible protection and isolated return, fault energy is minimized and maintenance intervals can be extended due to rugged construction. Its compatibility with 600 VDC PV circuits and straightforward wiring reduces installation time, lowers labor costs, and helps achieve faster commissioning and system reliability.
