About Fuses

UL Class CC Fast-Acting Midget Fuses

These fuses open circuits quickly when surges are detected.

UL Class J Fast-Acting Fuses for Tight Spaces

These fuses open circuits quickly when surges are detected.

UL Class RK1 Fast-Acting Fuses

These fuses open circuits quickly when surges are detected.

UL Class K5 Fuses

Use these fast-acting fuses in applications where temporary overload current is not present, such as in lighting and heating.

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.

UL Class G Fast-Acting Midget Fuses

These fuses open circuits quickly when surges are detected.

UL Class H Replaceable-Element Fuses

Replace the current-carrying element rather than the entire fuse after the fuse breaks. These fuses are fast-acting.

Replacement Elements for UL Class
H Replaceable-Element Fuses

Fast-Acting Glass-Tube Fuses

These fuses open circuits quickly when surges are detected.

Fast-Acting Ceramic-Tube Fuses

These fuses open circuits quickly when surges are detected.

Fast-Acting Midget Fuses

These fuses open circuits quickly when surges are detected.

Fuses for Sensitive Electronics

With a quicker response than standard fast-acting fuses, these fuses provide the best protection for sensitive electronics.

Fuses for Multimeters

Compatible with most multimeters, including Fluke.

1,000V DC Fuses

Developed for the solar industry, these fuses meet the needs of high-voltage DC applications.
