Eaton FL3K100 Fuse Link Type K

The Eaton FL3K100 Fuse Link provides essential overcurrent protection for distribution networks within the medium-voltage segment of the electrical grid, operating as a precision component within Eaton or Cooper Edison high-voltage fuse holders. With a continuous current rating of 100 amperes and a 27 kilovolt voltage classification, this fast-acting Type K fuse is engineered to melt under short-circuit conditions while maintaining stability against normal load surges and thermal cycling inherent in demanding commercial power grids or heavy industrial operations. The unit measures 24 inches in overall length, ensuring mechanical compatibility with existing mounting structures and standardized fuse clips used in outdoor substations. Technicians utilize this specific replacement part to recover system functionality after a trip event, maintaining the integrity of the coordination profile required for reliable electricity delivery, preventing cascading failures across the grid during emergency maintenance situations.
