Eaton DCG4064URM DC Disconnect - 600V, NEMA 3R
Part Number: DCG4064URM
Quick Summary
Eaton heavy-duty DC disconnect safely interrupts and isolates solar DC power for photovoltaic systems. Engineers often struggle with rugged outdoor enclosures, space constraints, and the need to meet strict safety codes. UL 98B, NEC 690 per UL 1741, and a NEMA 3R rating help ensure compliant, weather-ready operation. This four-pole, non-fusible device simplifies wiring, isolation, and maintenance, while the painted galvanized steel enclosure resists the elements. The DCG4064URM supports In/Out LC and SR lugs up to 300 kcmil-#6, is grounded, and delivers a clear, field-proven path to reliable solar DC protection, aligning with project schedules and total cost of ownership goals.
