Compare across fuse type, UL class, and voltage. Then cross-reference manufacturer part numbers to find suitable replacements.
UL Class RK5 Fuses
 |  |
Ferrule Cartridge Fuse, Without Blown Fuse Indicator | Knife-Blade Cartridge Fuse, Without Blown Fuse Indicator |
Also known as dual-element fuses, these time-delay 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. They have a rejection-style end design that safeguards against replacement errors. Use with Fuse Blocks for UL Class RK5 Fuses.
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.

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

UL Class RK1 Time-Delay Fuses
 |
Ferrule Cartridge Fuse |
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. They have a rejection-style end design that safeguards against replacement errors. Designed for use with Fuse Blocks for UL Class RK1 Fuses.
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.

Time-Delay Ceramic-Tube Fuses
|
1/4" Dia. |
Able to withstand current overload for a short time, these fuses will not open when exposed to harmless temporary surges. They can withstand temperature swings and high ambient temperatures better than glass-tube fuses. Use them with electronics, control panels, and other sensitive components. Select these fuses by their diameters. Designed for use with Fuse Blocks for Ceramic-Tube Fuses.
1/4" Overall Diameter—1/4" dia. fuses can be used in high-current electronic circuits such as microwave ovens.
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.
