This is the maximum current, which the fuse will carry for an indefinite period without undue deterioration of the fuse element.

Current rating can be defined as the maximum current carrying capacity of the power cable under normal operating condition

The maximum current in amperes, at rated current and frequency, that a device will carry continuously under defined conditions without exceeding specified performance limits.

The amount of electrical current flow a device has been designed to withstand. Cutout - An assembly of a fuse support with either a fuse holder, fuse carrier, or disconnecting blade. A fuse holder or fuse carrier may include a conducting element (fuse link), or may act as the disconnecting blade by the inclusion of a non-fusible member.

Units:  A Rated output current of power supply. Rated output current of power supply. A

The safe current-carrying capacity of a wire or cable on a continuous basis. See AWG [wire gauge].

Designation of rating given in amperes at which the device will not trip. A specific temperature is usually assigned.

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).
