Power dissipated from the device while in the tripped state.

Refers to the temperature of the air immediately surrounding the fuse and is not to be confused with "room temperature." The fuse ambient temperature is appreciably higher in many cases, bec [..]

Without crystallization in the ultimate texture of a solid substance. Used to describe the material structure in the tripped state of a Multifuse® device.

The SI unit of measure for electrical current. The unit of electrical current or rate of flow of electrons. 1 ampere = 1 coulomb of charge/second.

A conductive material used in Multifuse® devices to provide a path for current flow under normal operating conditions.

The flow of electric charge that transports energy from one place to another. Measured in amperes, where one ampere is the flow of 6.25 x10^18 electrons (or protons) per second.

The maximum current a Multifuse® device can pass without interruption.

The maximum fault current a Multifuse® device can withstand without damage at the rated voltage.

The nominal amperage value marked on the fuse. It is established by the manufacturer as a value of current which the fuse can be loaded to, based on a controlled set of test conditions (see Rerating).
