Eaton KTN-R-80 Fuse - Class RK1, 80 A, 200 kAIC at 250 Vac

Feature: Fast-acting current-limiting Class RK1 fuse design. Benefit: Quickly interrupts fault currents to minimize damage to downstream devices, reducing downtime and extending equipment life in industrial controls. Application: Ideal for motor starters, control panels, and machine feeders where fast clearing is critical. Effect: Improves overall equipment efficiency and reliability in manufacturing environments.Feature: High interrupt ratings of 200 kAIC at 250 Vac and 100 kAIC at 250 Vdc. Benefit: Withstands severe short-circuit conditions without catastrophic failure, lowering arc energy exposure and protecting power distribution infrastructure. Application: Main buses and branch circuits in harsh production lines facing high fault duties. Effect: Enhances safety margins and reduces unplanned outages.Feature: 80 A amperage with 250 Vac and 250 Vdc voltage ratings. Benefit: Provides precise protection for medium- to high-current circuits while remaining compatible with standard industrial power supplies. Application: Control circuits, drives, and protected loads in automation systems. Effect: Supports compliant protection sizing and predictable fuse coordination.Feature: Solid construction with Melamine glass tube, 1 element, and 70/30 brass end caps. Benefit: Durable performance under thermal and vibration stress, plus reliable contact integrity during operation. Application: Panel-mounted fusing in rugged environments where long life and stable contacts are required. Effect: Reduces maintenance frequency and enhances connection reliability.Feature: Blade end x blade end connection and standard packaging. Benefit: Simple, drop-in replacement in existing RK1 fuse holders, streamlining maintenance and spare parts inventory. Application: Retrofit projects or new installations in machine rooms and electrical closets. Effect: Minimizes downtime during fuse changes and supports fast repair cycles.
