High voltage, high current capability enables safe isolation of 1500 VDC systems with a 400 A rating for a single circuit. The DCG1155FDM-000W is engineered for solar PV, energy storage, and industrial DC distributions, delivering reliable fault isolation with fast switching. This design minimizes arc flash risk and simplifies de-energization procedures, supporting safer maintenance windows and lower incident severity. Fusible protection within the enclosure provides overcurrent protection without needing extra fuses, improving protection coordination and reducing BOM complexity. The integrated fuse path supports selective protection schemes and quick replacement, cutting downtime during battery storage or DC bus faults. Enclosure rated NEMA 12/3R provides dust, splash, and corrosion resistance in indoor and semi-outdoor installations. Painted galvanized steel adds durability in harsh plant environments, while the upper window offers fast visual status indicators. This combination supports quick commissioning and long service life in aggressive industrial settings. With a footprint of 8.15 in depth, 24.12 in width, and 57.47 in height, and a weight of 138.2 lb, the unit is designed for floor-standing or cabinet-anchored installations. The upper window and sturdy mounting provisions simplify wiring access and field service, while the 1 Ckt, 400 A configuration aligns with common utility and contractor installation practices. UL Listed certification confirms compliance with safety standards for heavy duty DC switches, while the DC ground type supports robust grounding schemes in DC power distribution. The Eaton DCG1155FDM-000W integrates seamlessly with standard modular switchgear, reducing integration risk in new builds or retrofits.

FAQs
When retrofitting into battery storage, plan for floor-standing or cabinet-mounted installation using the enclosure’s 8.15 in depth, 24.12 in width, and 57.47 in height. Ensure indoor or ventilated spaces accommodate the 138.2 lb weight and use the NEMA 12/3R enclosure to protect against dust and moisture. Check that the system is grounded via the DC ground type and that UL Listed protection is maintained throughout wiring.
The integrated fusible protection provides overcurrent protection for a single circuit, enabling selective protection without additional fusing components. This simplifies the protection scheme, reduces BOM complexity, and speeds fault isolation, which translates to shorter downtime and safer, more predictable maintenance in high-voltage DC installations.
Yes. With a 1500 VDC rating, 400 A capacity, and a single fusible circuit, it supports both solar PV DC combiner applications and industrial DC distribution. The NEMA 12/3R enclosure and upper status window facilitate safe, quick servicing in demanding environments, while UL Listed certification ensures compliance for energy projects and drive systems.
The DCG1155FDM-000W is UL Listed, indicating conformance to recognized safety standards for electrical equipment. It uses a NEMA 12/3R enclosure with painted galvanized steel, suitable for indoor and semi-outdoor environments. The DC ground type and 1500 VDC rating align with high-voltage DC distribution safety requirements, simplifying regulatory compliance in modern energy systems.
Expect reduced maintenance downtime due to integrated fusible protection and a simplified single-circuit design, which lowers spare parts and replacement frequency. The rugged enclosure and UL certification provide long service life in harsh environments, improving uptime and return on investment in solar, energy storage, and industrial DC power applications.
