General Information:

• 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.

• LIMITRON fuses are 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 non­rejection type fuseholders. Thus, can physically and electri­cally replace fast-acting Class H, K1, K5, RK5, and other
fast-acting fuses.
