Features: Catalog Symbol: KTS-R-(amp) Single-element, fast-acting fuses with minimal time-delay Ratings: Provides a high degree of short-circuit current-limitation (component protection) Volts 600Vac Particularly suited for circuits and loads with no heavy surge Amps 1-600A currents of motors, transformers, solenoids, and welders IR 200kA Vac RMS Sym. Commonly used to protect circuit breakers with lower inter- rupting ratings. Agency Information: If used in circuits with surge currents (motors, etc.) must be CE, UL Listed, Std. 248-12, Class RK1, Guide JDDZ, sized to prevent unwanted opening. It is recommended to File E4273 use an ultimate protection Low-Peak LPS-RK time-delay fuse for inductive load applications.
