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.

UL Class J Time-Delay Fuses for Tight Spaces

Ferrule Style with Blown-Fuse Indicator

Knife-Blade Style with Blown-Fuse Indicator

Also known as dual-element fuses, these fuses withstand current overload for a short time so they won't open when exposed to harmless temporary surges, such as when starting a motor. More compact than UL Class RK1 or RK5 fuses, they are suitable for tight spaces. Use with Fuse Blocks for UL Class J 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.

Fuses with blown fuse indicator have a dot on the side that changes color when the fuse blows.

Fast-Acting Ceramic-Tube Fuses

1/4" Dia.

These fuses open circuits quickly when surges are detected. They can withstand temperature swings and high ambient temperatures better than glass-tube fuses. Use with electronics, control panels, and other sensitive components. Select these fuses by their diameters. Designed for use with Fuse Blocks for Ceramic-Tube 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.

1/4" dia. fuses can be used in high-current electronic circuits such as microwave ovens.
