FAQs
For outdoor solar arrays, install the DCG1105FPM in a protected location or weatherproof enclosure as required by your project. Ensure solid grounding and isolated return are maintained, verify that the enclosure remains sealed to prevent moisture ingress, and route conductors to minimize exposure to moisture, corrosion, and mechanical stress. Regular inspection should focus on terminal connections and enclosure integrity.
The DCG1105FPM is rated for 400 A and 1000 VDC with a single circuit. It provides fusible protection and grounded operation with an isolated return, delivering safe DC fault isolation and protection for PV strings and DC distribution points in solar installations.
Yes. With a 400 A rating and 1000 VDC capability, the DCG1105FPM is adaptable for either string-level disconnections in mid-size to large PV installations or central DC distribution points. Its NEMA 4 enclosure and fusible protection help meet outdoor installation requirements and simplify system layout and safety compliance.
The DCG1105FPM carries UL Listed certification and a NEMA 4 rating. UL Listing confirms compliance with safety standards, while NEMA 4 provides weatherproof protection for outdoor installations. Together, they help meet regulatory requirements and industry best practices for solar and other DC PV applications.
Maintenance is focused on periodic inspection of fusible elements, terminal connections, and enclosure integrity, with attention to corrosion resistance and seal performance. The 25-000 Eaton warranty supports uptime, and reliable protection reduces unplanned downtime in PV systems, contributing to a lower total cost of ownership over the asset’s lifecycle.
