Automotive Fuses

These fuses are suitable for low-voltage automotive and other electronic applications. Use with Fuse Blocks for Automotive Fuses.

Fast Acting—Fast-acting fuses open circuits quickly when surges are detected.

With Blown Fuse Indicator—Fuses with blown fuse indicator have a light that turns on when the fuse blows.

Breakthrough Current @ Voltage—Breakthrough current at voltage, labeled on the fuse as IR, is the maximum current that a fuse can safely stop in the event of a short circuit.
