Feature → Business Impact → Application: 800 A amperage rating with Class L fuse and fusible with neutral enables coordinated protection for large motor circuits, reducing nuisance fuse operations and improving safety during isolation. This translates to higher equipment availability and lower maintenance costs on 480/600 V motor feeders across manufacturing lines. Feature → Business Impact → Application: NEMA 3R enclosure built from painted galvanized steel provides durable outdoor and harsh-environment protection, minimizing corrosion risk and maintenance while enabling installation in outdoor substations and exposed plant areas. Feature → Business Impact → Application: Three-pole, four-wire configuration with a neutral simplifies wiring schemes for standard three-phase systems, streamlining installation and making retrofits or expansions straightforward in warehouses and process facilities. Feature → Business Impact → Application: NEC 230.62 compliant barrier and UL Listed certification deliver regulatory alignment and safer work practices, reducing project risk and speeding approvals for new builds or upgrades. Feature → Business Impact → Application: Max HP rating of 500 hp (3PH @480/600 V) and 600 V rating support high-demand drives, delivering predictable protection for large motor loads in packaging, textile, and water treatment applications. Feature → Business Impact → Application: Overall dimensions (57.5 in length, 27.5 in width, 12.38 in height) and a 210 lb weight provide a clear installation footprint, improving planning accuracy for equipment rooms and outdoor areas and informing crane/rigging needs when deploying in new or upgraded facilities.
