FAQs
The DCG1155UDM-000W is designed for indoor high-voltage DC distribution, handling 1500 VDC and up to 400 A in a single 1-circuit arrangement. It fits control rooms, manufacturing floors, and energy storage installations where reliable isolation, safety, and UL-listed compliance are required. Its NEMA 12/3R enclosure supports rugged indoor environments, while its non-fusible design simplifies maintenance planning.
UL Listed signifies compliance with recognized safety standards, reducing regulatory risk and accelerating approvals during audits and new installations. For maintenance planning, UL listing provides confidence in component reliability and documented safety performance, enabling safer servicing of high-voltage DC systems without requiring extensive requalification for each project.
Yes. The DCG1155UDM-000W is a single-circuit, non-fusible DC disconnect designed for straightforward integration into DC distribution schemes. Its 1500 VDC rating and 400 A capacity align with typical high-voltage DC buses, and the NEMA 12/3R enclosure simplifies cabinet layout. Always verify conductor sizing, enclosure space, and protective clearances per applicable electrical codes during commissioning.
The NEMA 12/3R enclosure is intended for indoor, rugged environments with protection against dust and moisture. The painted galvanized steel construction offers durability in factory floors and control rooms. When planning installation, ensure proper indoor mounting clearances, secure fastening to a stable surface, and alignment with service access windows for maintenance checks. Outdoor use or exposure to weather requires alternative enclosures or protections.
Expect improved uptime due to reliable high-voltage isolation and a non-fusible design that reduces maintenance complexity. The UL Listed rating supports faster regulatory clearance, while the sturdy enclosure minimizes corrosion-related downtime. Although initial cost is higher than basic disconnects, long-term savings come from reduced outages, safer maintenance, and easier system upgrades in energy storage and manufacturing DC networks.
