About Fuses

Designed to handle high inrush currents and the initial current cycle unique to transformers, these fuses provide comparable performance with a smaller footprint than standard size fuses. Use them to protect power distribution branch circuits. They’re for use with Fuse Blocks for UL Class CC Fuses.

Fuses with a rejection-style end safeguard against replacement errors.

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.
