Eaton DCU1155FDM-000W DC Disconnect - UL Listed

Heavy‑duty construction enables reliable isolation in high‑voltage DC networks. The DCU1155FDM-000W delivers 1500 VDC and 400 A in a single‑circuit fusible design, reducing arc flash risk and protecting your power rails. In solar installations and battery storage systems, this translates to safer maintenance windows and predictable fault clearance. With a single circuit and fusible protection, wiring complexity is minimized and space is conserved in control panels, simplifying cabinet layout, speeding installation, and lowering commissioning time in continuous‑process environments. Its NEMA 12/3R‑rated enclosure, painted galvanized steel, keeps dust and moisture out while maintaining mechanical integrity in harsh industrial settings. The upper window provides visual confirmation of fuse status without opening the enclosure, supporting faster diagnostics. Designed for straightforward mounting and compatible with common Eaton switching devices, the DCU1155FDM-000W integrates with existing protection schemes and replacement parts. Its UL Listed status reinforces compliance with North American electrical codes, helping meet procurement standards and reducing vendor risk. Investing in a dedicated DC disconnect reduces unscheduled downtime and extends equipment life by ensuring immediate, safe isolation during faults. The combination of 1500 VDC rating, robust enclosure, and fused protection delivers predictable performance that supports compliance efforts and lowers total cost of ownership in energy‑intensive facilities.
