Feature → Business Impact → Application: The 60 A amperage rating provides headroom for typical solar strings, reducing the likelihood of nuisance tripping and enabling safer, compliant protection in mid-size PV installations. Application: solar PV arrays and ungrounded DC systems where reliable protection and easy maintenance are required. The 3-circuit design offers modular separation of strings, improving fault isolation and service speed in rooftop or ground-mounted setups. This supports faster commissioning and easier future expansion without major rewiring. Feature → Business Impact → Application: NEMA 4X enclosure with 304 stainless steel delivers corrosion resistance and washdown capability, decreasing maintenance costs in dusty, salty, or humid environments. Application: outdoor PV enclosures on rooftops, carports, or harsh industrial sites. Feature → Business Impact → Application: Ungrounded, non-fusible configuration simplifies testing, reduces arc-flash exposure risk during service, and aligns with PV system safety practices. Application: solar installations requiring straightforward non-fusible DC protection. Feature → Business Impact → Application: 600 VDC system voltage supports modern PV strings, enabling safer and compliant interconnection with mid- to high-voltage modules. Application: solar arrays with higher-voltage strings. Feature → Business Impact → Application: Main lug capacity for #14-#2 AWG lugs and #14-1/0 AWG solid return reduces splicing and simplifies field wiring. Application: quick, reliable onboarding of conductors in new builds or upgrades. Feature → Business Impact → Application: The Eaton warranty (one year from installation or 18 months from shipment) provides risk mitigation and predictable maintenance planning. Application: project handover and ongoing asset management for industrial solar systems.

FAQs
What mounting options and wiring configurations are supported by DCU3062UWM for outdoor PV installations? This unit uses a sturdy NEMA 4X enclosure in 304 stainless steel and supports up to three separate circuits. It accepts lug sizes from #14 to #2 AWG with a solid return up to #1/0 AWG, enabling quick, code-compliant field wiring and safer maintenance access in rooftop or ground-mounted arrays.
DCU3062UWM is designed specifically for PV applications with a 60 A rating, three circuits, ungrounded configuration, and 600 VDC maximum. Its non-fusible protection and rugged NEMA 4X enclosure in 304 stainless steel provide reliable outdoor protection, while NEC 690 per UL 1741 and UL 98B compliance ensures safety and performance in solar electrical protection tasks.
This disconnect aligns with NEC 690 as referenced by UL 1741, and UL 98B for enclosure protection. The NEMA 4X rating and 304 stainless steel enclosure further certify its outdoor durability and suitability for harsh environments, making it a compliant choice for utility-scale and rooftop PV deployments.
Main lug capability supports #14-#2 AWG lugs with a solid return up to #14-1/0 AWG. This reduces splicing and simplifies wiring for multiple PV strings. The 60 A rating covers typical string currents, and the 600 VDC rating supports standard PV module arrays, offering safe, scalable wiring in compact footprints.
Eaton provides a warranty under policy 25-000: one year from installation or eighteen months from shipment, whichever occurs first. This reduces lifecycle risk, supports predictable budgeting, and ensures access to Eaton support for field issues, replacements, or technical guidance during the critical commissioning phase.
