Bussmann series KTS-R 600 V Class RK1 fuse data sheet no. 1044
Class RK1, fast-acting fuse design delivers targeted protection for motor controllers, reducing arc energy and enabling selective coordination. This directly lowers downstream damage and minimizes unplanned downtime in manufacturing lines and packaging facilities, while maintaining safety margins needed for critical drives. The current-limiting characteristic with a 200 kAIC interrupt rating at 600 Vac enhances equipment protection during short-circuit events and supports compliant protection schemes in switchgear and control panels. An 80 A rating paired with a single melamine glass tube provides predictable performance and simplifies fuse sizing for common motor-control circuits. Ferrule design with blade-end x blade-end connections offers robust terminations, enabling faster, more reliable installations in both retrofits and new builds. The fuse’s compact footprint and 0.5 lb weight maximize panel density while preserving ease of maintenance and serviceability. Non-indicating indicators reduce panel visual clutter, suitable for control rooms and automated environments, with CE Marking confirming international safety compliance and broad procurement acceptance.
