Eaton KTN-R-150 Fuse - 200 kAIC at 250 Vac Class RK1

Fast-acting, current-limiting design minimizes fault energy and protects downstream electronics, reducing arcing, insulation stress, and component wear. This translates to longer equipment life and fewer unplanned maintenance cycles in automated systems. In practice, you get more predictable protection for power supplies, drive electronics, and I/O interfaces in industrial control panels and machine control cabinets where transient faults are common. An amperage rating of 150 A paired with a 200 kAIC interrupt rating at 250 Vac enables safe interruption of high-energy faults without nuisance trips elsewhere in the system. The result is higher line availability and reduced downtime on production lines, critical for packaging, assembly, and process industries where rapid fault isolation matters. Class RK1 construction and 70/30 brass end caps improve contact reliability and durability under vibration and thermal cycling. Blade-end connections streamline integration with standard Bussmann series holders, supporting straightforward field retrofits, consistent stocking across sites, and faster design-in for control panels with minimal engineering overhead. Compact physical footprint supports dense panel layouts: 7.1 inches long, 1.56 inches wide, 1.56 inches high, and about 0.92 lb. The single-element, melamine glass tube construction offers robust performance in harsh environments while enabling easy replacement and minimal panel intrusion during maintenance. Procurement and design workflows benefit from full compatibility with Bussmann catalogs and data sheets, including the KTN-R data sheet no. 1043. This simplifies specification, verification, and ordering across automation projects, reducing risk of mismatch and supporting consistent protection strategies across machines and facilities.
