Features:
• 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 and thus only provide
short-circuit protection
• 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 fast-
acting fuses.
