Eaton DCG4065FPM DC Disconnect - UL Listed, NEMA 4
Part Number: DCG4065FPM
Quick Summary
Eaton heavy duty DC disconnect provides safe, code-compliant DC power isolation for solar installations. Engineers often struggle with bulky enclosures, under-rated protections, and complex wiring in large PV projects. UL Listed safety, NEMA 4 weather resistance, and a 600 VDC four-pole design help ensure compliance and long-term reliability in outdoor sites. Painted galvanized steel enclosures, fusible protection, and a 400 A rating translate into easier field installation, fewer field modifications, and reduced downtime. This solution balances rugged performance with installation flexibility, making it suitable for solar arrays, battery charging, and utility-scale PV applications while delivering tangible business value through improved reliability and lower lifecycle costs.

The 400 A four-pole design provides robust fault isolation and high current handling, reducing arc flash risk and simplifying protective coordination for large solar installations. This translates to faster commissioning, fewer reworks, and lower total cost of ownership as system upsets are contained at the source. The NEMA 4 enclosure, crafted from painted galvanized steel, delivers weatherproof protection for outdoor PV sites, improving uptime in rain, dust, and exposure to the elements. Large main lug wire sizes (LC and SR configurations) enable streamlined terminations with 750 kcmil-1/0 and 600 kcmil-#2 conductors, supporting rapid field wiring and future capacity upgrades without hardware changes. The fusible protection and 600 VDC per pole rating align with common solar DC requirements, ensuring compliance and predictable performance across a broad range of PV architectures. Compatibility with 4-pole, DC photovoltaic applications makes integration straightforward, while Eaton’s specification data and UL Listed certification support installation QA and ongoing maintenance in regulated environments.
