GSL Equivalent Fuse and S Equivalent Fuse—Type GSL and S fuses have a non-interchangeable base to prevent the wrong size fuse from being used.
GTL Equivalent Fuse, TL Equivalent Fuse, and TLO Equivalent Fuse—Type GTL, TL, and TLO fuses can be used in motor applications.
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.

Touch-Safe Fuses
 |
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.
With Blown Fuse Indicator—Fuses with blown fuse indicator have a dot on the side that turns red 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.
