The 30A amperage rating across three poles provides controlled isolation for small to medium PV strings, with a non-fusible design that simplifies compliance and reduces nuisance tripping. This translates to faster maintenance and predictable lockout/tagout procedures in the field, enabling technicians to safely isolate solar arrays without compromising system uptime. In solar applications, a three-pole, grounded, non-fusible disconnect ensures consistent performance across daily start-ups and fault conditions. The 304 stainless steel enclosure with NEMA 4X rating offers robust corrosion resistance and ingress protection, reducing enclosure damage and maintenance costs in outdoor installations, such as rooftops or carport PV setups. Engineers benefit from longer service life and reduced cosmetic degradation while keeping a professional exterior look. Main lug wiring supports In/Out(LC): #2-#14 AWG and In/Out(SR): 1/0-#14 AWG, enabling straightforward field terminations and minimizing rework during commissioning. This compatibility shortens installation time and lowers inventory complexity for standard PV conduits. The 600 VDC system voltage and per-pole rating align with modern PV arrays, ensuring safe operation under peak input conditions and simplifying electrical design. The isolated return, combined with a non-fusible protection scheme, enhances maintenance safety and reduces arc-flash exposure during routine service. The enclosure’s NEMA 4X rating is reinforced by detailed Eaton documentation, fostering rapid approvals during project handoffs and rigorous commissioning. A one-year warranty, extendable to eighteen months from shipment, gives procurement teams confidence in expected lifecycle costs while Eaton’s datasheets and dimension tables clarify the exact circuit configurations available for a given amperage.

FAQs
For installation, ensure the device is configured as a three-pole, grounded, non-fusible DC disconnect rated for 600 VDC. Use In/Out(LC) wiring up to #2-#14 AWG or In/Out(SR) up to 1/0-#14 AWG, and mount the unit within a NEMA 4X rated enclosure to withstand outdoor exposure. Follow NEC 690 guidelines and secure lockout/tagout procedures during service.
The DCG3061UWM is specified for NEC 690 in conjunction with UL 1741 and UL 98B, ensuring it meets solar PV isolation and overcurrent protection standards. Its non-fusible, isolated-return design plus NEMA 4X enclosure support safe operation in outdoor PV systems and align with regulatory expectations for industrial DC protection equipment.
Yes. The unit features a 304 stainless steel enclosure with a NEMA 4X rating, designed to resist corrosion and ingress in outdoor environments such as rooftops and carports. Its grounded, isolated-return configuration also enhances safety during maintenance, making it a reliable choice for outdoor solar DC protection.
Isolated return provides clear separation between input and output conductors, reducing fault paths and simplifying troubleshooting. The non-fusible design reduces nuisance tripping and simplifies field maintenance, while still offering reliable isolation for routine servicing and de-energization of PV strings in a controlled, safe manner.
Eaton provides a specification sheet (DCG3061UWM) detailing wiring, dimensions, and configurations, along with installation notes and YouTube safety videos. The enclosure and component data support regulatory submissions and quick project handoffs, helping procurement and engineering teams expedite approvals and field commissioning.
