UL Class T Fuses for Extra-Tight Spaces

Ferrule Style
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.
