About Fuses

These fuses can withstand the high inrush current caused by a motor starting. They provide comparable performance with a smaller footprint than standard size fuses. All have a rejection-style end that safeguards against replacement errors. Use them to protect power distribution branch circuits. Designed for use with Fuse Blocks for UL Class CC 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.
