FAQs
DCU1062FXM is designed to integrate with Eaton’s DC PV accessories and other ungrounded DC components. The unit supports versatile lug options and a 60 A rating, enabling straightforward wiring within standard electrical rooms or outdoor cabinets. When planning, verify lug sizes (#14-#2 AWG lug capacity, #14-1/0 AWG solid return) and ensure the enclosure can be securely mounted to maintain NEMA 4X protection in outdoor environments.
Key specs include a 60 A amperage rating, 600 VDC maximum per pole, and fusible protection. The 1-circuit design simplifies protection coordination for PV strings, while the ungrounded configuration reduces neutral-related complexities. Together with UL 98B and NEC 690 compliance, these features support reliable, code-conforming PV isolation and safe maintenance access.
Yes. The enclosure is NEMA 4X rated and constructed from 316 stainless steel, delivering superior corrosion resistance and weatherproofing. This makes the unit well-suited for outdoor PV sites subject to moisture, dust, and temperature variations, helping extend service life and reducing enclosure-related maintenance.
The device is UL 98B listed and complies with NEC 690 per UL 1741, aligning with recognized safety and solar-specific electrical standards. Such certifications ensure proper fault protection, safe operation in PV environments, and compliance with national electrical codes, giving project teams confidence during procurement and inspections.
Expect lower maintenance frequency due to durable 316 stainless steel construction and a rugged NEMA 4X enclosure that withstands outdoor exposure. The fusible protection and straightforward wiring reduce downtime during service or replacements, while the compact footprint and compatible lug options speed installation—translating to shorter project cycles and improved uptime for solar operations.
