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 inter-

rupting 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 fast-

acting fuses.
