FAQs
The DCG2104UPM is designed for solar photovoltaic systems and other 1000 VDC installations. It provides two isolated circuits, 200 A capacity, and a NEMA 4 rated enclosure for outdoor or challenging environments, enabling safe, code-compliant DC isolation and straightforward integration into existing DC rail layouts.
Main lug sizing supports LC: 300 kcmil-#6 in/out, SR: 300 kcmil-#6 in/out, and EG: in #4-#14 AWG out 1/0-#14. This variety allows flexible wiring schemes, simplifies retrofits, and reduces the need for additional components when upgrading PV or DC circuits.
The DCG2104UPM meets UL 98B and NEC 690 per UL 1741 requirements, and it is housed in a NEMA 4 enclosure with painted galvanized steel. These certifications ensure combustible safety, rain and dust resistance, and compliance for outdoor solar and industrial DC protection.
The non-fusible, grounded with isolated return design provides clearer fault isolation and safer de-energization. A rugged NEMA 4 enclosure protects internal components from environmental ingress, reducing corrosion-related maintenance. Together with UL/NEC compliance, this reduces downtime and helps meet stringent safety programs and audits.
Yes. The unit supports common conductor sizes and isolated return configurations, enabling straightforward integration into current DC solar or industrial setups. Its robust enclosure and grounding option help align with typical plant grounding schemes, while its portable form factor and clear labeling streamline commissioning and maintenance activities.
