Fuses

A fuse is a device that, by the fusion of one or more of its specially designed and proportioned components, opens the circuit in which it is inserted and breaks the current when this exceeds a given value for a sufficient time. The fuse comprises all the parts that form the complete device (BS 88). We see in the definition that the fuse is the complete device, consisting of a fuse-holder (which comprises a fuse base and fuse carrier) and a fuselink.
