Three-pole, non-fusible DC disconnect rated at 100 A per pole provides a robust single-point isolation for DC bus sections. This arrangement minimizes arc flash exposure during maintenance and creates clear fault boundaries that technicians can trust. In PV systems, the configuration supports safe disconnects between array sections, combiner boxes, and inverter inputs, delivering predictable operation and faster fault localization in real-world sites. NEMA 4 enclosure and painted galvanized steel construction protect the disconnect from wind-driven rain, dust, and corrosion. This rugged housing reduces service calls and extends equipment life in outdoor or industrial environments. The enclosure supports simple field mounting and cable routing, helping installers meet tight project schedules without compromising safety. Grounded system compatibility and isolated return improve fault detection and safety margins. The DCG3063UPM’s grounding strategy aligns with common PV topologies, enabling straightforward integration with monitoring, PV disconnects, and overcurrent protection schemes. This reduces the need for custom wiring tricks and improves overall reliability in utility-scale and commercial deployments. Main lug wiring accepts In/Out LC/SR: 1/0-#14 AWG, simplifying procurement and installation by using widely available PV conductors. The three-pole design and clear labeling support efficient wiring and future expansion, while non-fusible protection minimizes unnecessary component changes. Installers benefit from faster wiring checks during commissioning and easier fault tracing in the field. UL 98B and NEC 690 with UL 1741 support, plus a NEMA 4 rating, provide strong regulatory alignment for solar projects. The combination of features establishes compliance confidence for audits, reduces risk in safety inspections, and helps protect warranties. For projects requiring outdoor reliability and scalable DC power distribution, this Eaton disconnect delivers long-term value and peace of mind.
