Prevent accidental contact with electrical circuits—these fuses have an enclosed design with recessed plug-in blades. Also known as dual-element fuses, they withstand current overload for a short time so they won't open when exposed to harmless temporary surges, such as when starting a motor.

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.

Fuses with blown fuse indicator have a dot on the side that turns red when the fuse blows.
