Feature → Business Impact → Application: 400 A amperage rating supports large solar installations without oversizing the main disconnect, reducing capital costs and panel counts while maintaining safe isolation. This feeds into improved reliability and faster maintenance cycles in utility-scale or commercial PV projects; engineers can select a single disconnect for a single circuit, simplifying wiring schemes and stocking. Feature → NEMA 4 enclosure delivers weather resistance, dust protection, and rain ingress prevention, ensuring uptime in outdoor installations and harsh industrial environments; the result is fewer weather-related faults and longer service intervals in rooftop and ground-mounted PV systems. Feature → Fusible protection provides a defined fault-clearing path, minimizing arc flash risk and enabling predictable protection coordination with other PV protection devices; this supports compliance with industry standards and safer field servicing. Feature → Ungrounded system compatibility reduces ground fault pathways and simplifies PV system topology, aiding installer flexibility and reducing integration costs. Feature → Painted galvanized steel enclosure offers durability and corrosion resistance, lowering maintenance costs and extending service life in challenging environments. Feature → UL Listed certification confirms formalized safety and performance benchmarks, facilitating procurement approvals and regulatory compliance in diverse jurisdictions. Feature → 600 VDC system voltage and per-pole voltage rating ensure compatibility with modern PV arrays and inverters, avoiding overrating or undersizing issues; this translates to scalable deployments and improved long-term ROI for capital projects.

FAQs

DCU1065FPM requires mounting in a NEMA 4 rated enclosure, with space for a single 400 A circuit, and conforming to 600 VDC per pole. Plan for ungrounded system wiring, fuse configuration, and accessible disconnect points to ensure safe maintenance and compliance with UL Listed standards. Verify clearance for door swing and adequate ventilation to prevent overheating during fuse operation.
Yes. The DCU1065FPM is specified for 600 VDC per pole and is designed for ungrounded DC photovoltaic applications. Its 400 A rating and fusible protection support safe isolation and protection coordination within PV arrays, while the NEMA 4 enclosure protects against environmental exposure.
The unit is UL Listed and features a NEMA 4 rated enclosure, which matters because UL Listing confirms adherence to recognized safety standards and performance criteria, while NEMA 4 ensures reliability in wet, dusty, and outdoor environments. These certifications facilitate procurement approvals and regulatory compliance for industrial and solar installations.
The DCU1065FPM provides a clearly identifiable, fusible disconnect point that reduces arc flash risk during service. Its robust enclosure and 600 VDC per pole capability enable safe, maintenance-friendly isolation, minimizing downtime and enabling faster fault diagnosis and replacement of fuses within PV systems.
Consider the 400 A rating, single circuit configuration, and NEMA 4 enclosure to determine if it matches your PV array size and environmental conditions. The UL Listed status simplifies compliance, while the durable painted galvanized steel housing lowers maintenance costs. The warranty and total installed cost versus downtime reduction should be included in lifecycle analyses to justify capital expenditure.
