• Single-element, fast-acting fuses with minimal time-delay
• Provides a high degree of short-circuit current-limitation (component protection)
• Particularly suited for circuits and loads with no heavy surge currents of motors, transformers, solenoids, and welders
• Commonly used to protect circuit breakers with lower interrupting ratings.
• If used in circuits with surge currents (motors, etc.) must be sized to prevent unwanted opening. It is recommended to use an ultimate protection Low-Peak™ LPS-RK time-delay fuse for inductive load applications.
• Incorporate Class R rejection feature. Can be inserted in non-rejection type fuse holders to physically and electrically replace fast-acting Class H, K1, K5, RK5, and other fastacting fuses.
