Bussmann series KTS-R 600 V Class RK1 fuse data sheet no. 1044
Feature: 500 A amperage rating with a 200 kAIC interrupt rating at 600 Vac. Business Impact: High fault-current scenarios are quickly cleared, protecting downstream equipment and reducing fault energy that can damage motors, drives, and switchgear. Application: Ideal for motor control centers, large panelboards, and power distribution assemblies where heavy fault currents are possible. Feature: Class RK1, fast-acting design. Business Impact: Rapid fault clearance improves selective coordination with upstream devices, minimizes arc energy, and helps prevent collateral damage in critical lines. Application: Suitable for distribution panels and MCCs in manufacturing and process facilities. Feature: Rejection style with knife blade. Business Impact: Safer handling during installation and maintenance, with easier field replacement and reduced risk of mis-insertion. Application: Retrofit projects and service workloads in enclosed cabinets. Feature: Physical footprint and weight. Business Impact: The 13.38 in length and 2.5 in square footprint fit standard Bussmann holders and 19 in rack enclosures, simplifying panel layout and reducing installation time. Application: Enclosures and switchgear assemblies with limited space. Feature: Compliance and packaging. Business Impact: CE marking confirms regulatory alignment; standard packaging and a single-element design streamline inventory and ordering. Application: New builds and spare-stock programs across industrial plants.
