UL Class T Fuses for Extra-Tight Spaces
Smaller than UL Class J fuses, these fast-acting fuses can be used in extra-tight spaces such as meters, uninterruptible power supplies, and variable-speed drives. They open circuits quickly when surges are detected. Use with Fuse Blocks for UL Class T Fuses.
Breakthrough current, also known as interrupt current, is the maximum current that a fuse can safely stop in the event of a short circuit.

Fast-Acting Inline Fuses
Also known as LGR fuses, these fuses protect fluorescent light fixtures. They open circuits quickly when surges are detected. You'll need both a fuse and a fuse holder (not included) to add an inline fuse to an existing circuit. Fuses have a built-in cap that securely connects to the fuse holder.
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.

Time-Delay Inline Fuses
Able to withstand current overload for a short time, these fuses will not open when exposed to harmless temporary surges. They are designed to handle high inrush loads from ballast transformers in fluorescent lighting systems. You'll need both a fuse and a fuse holder (not included) to add an inline fuse to an existing circuit. Fuses have a built-in cap that securely connects to the fuse holder. Also known as LMF 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.
