FAQs
When deploying the DCG4065FXM in solar PV installations, plan for outdoor mounting with the 316 stainless steel NEMA 4X enclosure to withstand weather conditions. Ensure properly rated conductors in the LC and SR lug configurations and verify the 600 VDC maximum voltage and four-pole fusible design are compatible with your array layout. Grounding provisions should follow site-specific electrical codes and Eaton guidelines. Field wiring should accommodate large conductors up to 750 MCM, with torque values per spec to maintain a secure connection and reliable protection.
Key specifications include a 400 A amperage rating, 600 VDC maximum system voltage, four-pole configuration, fusible protection, and grounded operation. It uses NEMA 4X enclosure with 316 stainless steel, suitable for solar DC applications. Main lugs accept substantial conductor sizes: LC side supports 750 MCM-1/0 and 600 MCM-#2, SR side supports 750 MCM-1/0. These features enable heavy-duty solar protection with robust fault isolation and simplified maintenance.
