UL Class K5 Fuses
Ferrule Style

Use these fast-acting fuses in applications where temporary overload current is not present, such as in lighting and heating. They open circuits quickly when surges are detected. Use with Fuse Blocks for UL Class K5 Fuses.
Breakthrough current, labeled on the fuse as IR, is the maximum current that a fuse can safely stop in the event of a short circuit.
