Eaton Specification Sheet - DH323FRKA1240
Heavy-duty 100 A, 240 V three-pole fusible switch provides safe, immediate isolation for motor circuits and feeders, reducing fault propagation and startup risk. This translates to lower downtime and easier troubleshooting in critical processes. Ideal for industrial power distribution panels and outdoor installations where reliable disconnection is essential. Enclosure protection is provided by a NEMA 3R painted galvanized steel shell, guarding internal components from weather, dust, and moisture, which translates to longer service life and lower maintenance costs in harsh environments. The fusible without neutral configuration with Class H fuses enables proper coordination and selective protection for motor circuits, minimizing nuisance outages and extending fuse life in plant utilities. An integrated 15A GFI receptacle enhances operator safety during maintenance and diagnostics, aligning with electrical codes and best practices for control panels. UL Listed certification supports regulatory compliance, simplifying procurement and audit readiness for new builds and retrofit projects. The compact footprint—depth 9.89 in, height 21.99 in, width 10.78 in—facilitates installation in tight panels, while compatibility with standard Eaton accessories streamlines installation and future upgrades.

FAQs
The DH323FRKA1240 is designed for motor control and feeder circuits in industrial panels, including outdoor or damp locations protected by its NEMA 3R enclosure. It integrates as a three-pole fusible switch rated for 100A at 240V, making it suitable for single-throw disconnect applications in manufacturing lines and utility panels.
The three-pole configuration with Class H fuses provides coordinated, selective protection for three-phase motor circuits. This reduces nuisance trips, protects the motor from overload, and simplifies maintenance by allowing straightforward fuse replacement without compromising the disconnect function.
Yes. The enclosure is rated NEMA 3R and manufactured from painted galvanized steel, offering protection against weather, dust, and moisture. This makes it well-suited for outdoor installations, wash-down areas, and demanding factory floors where reliability and durability are essential.
The product is UL Listed, ensuring compliance with widely adopted electrical safety standards. This certification, combined with the NEMA 3R enclosure and standard mounting compatibility, supports regulatory adherence and smoother acceptance in code-required installations.
Maintenance is simplified by using Class H fuses and a built-in 15A GFI receptacle for service tooling, reducing downtime during maintenance cycles. The robust enclosure and UL-listed certification contribute to lower lifecycle costs through extended service intervals, fewer field failures, and faster project approvals in retrofit or new-build projects.
