Eaton Specification Sheet - DH223NRKLPR
The 100A amperage rating translates to robust protection for demanding loads such as motors and conveyors, delivering measurable efficiency gains and reduced downtime. This safety switch’s fusible with solid neutral configuration simplifies fuse coordination while offering predictable fault clearing, which protects both equipment and personnel during maintenance or upgrades. The 2-pole design at 240V provides a clean, straightforward disconnect that minimizes wiring complexity in control panels and switchgear assemblies, improving installation speed and accuracy. Posi-Lok reverse pin enhances enclosure alignment and engagement, reducing mis-feed risks during maintenance or modular upgrades in factory cabinets. The Series K construction supports quick-connect style wiring and rugged, long-life operation in industrial environments, while the UL Listed certification and NEMA 3R enclosure support conformance to safety and environmental standards. The switch’s compact footprint versus its high capacity aids in panel space optimization, lowering overall system cost and enabling easier retrofits. In practice, maintenance teams report easier diagnostics and faster part swaps thanks to standardized mounting and wiring footprints, which translates into lower total cost of ownership for industrial protection schemes.
