About Fuses

These fuses can withstand the high inrush current caused by a motor starting. They provide comparable performance with a smaller footprint than standard size fuses. All have a rejection-style end that safeguards against replacement errors. Use them to protect power distribution branch circuits. Designed for use with Fuse Blocks for UL Class CC 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.

Thermal Fuses

Inline Leads

Also known as thermal cut-offs, these fuses prevent equipment from overheating by opening circuits to cut off power. They react to excessive temperature in the same way electrical fuses react to excessive current. They can’t be reset, so replace them once they open.

Choose a fuse based on your device's normal operating temperature and the temperature at which you want the fuse to trip. Opening temperature is the temperature at which the fuse trips and turns off the device. Maximum operating temperature is the highest temperature a fuse can handle on an ongoing basis. These fuses tolerate temperature spikes that fall between the two values, but prolonged exposure to temperatures above the maximum operating temperature may cause the fuse to fail.

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.

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.

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.

Fuses with blown fuse indicator have a dot on the side that turns red when the fuse blows.
