An electrical fuse comprises a conductor arranged with a U-shape where the desired break point is at the base of the U so that the mutually repellant magnetic fields around the two limbs of the U cause their separation at the break-point at the fusing current. In an embodiment (Fig. 2) a fuse carrier 17 comprises a plate 18 with dependent oppositely curved flanges 19 carrying leaf contacts 20 and a bridge member 21 separating the flanges around three sides of which passes a fusing link 23. The carrier is engageable with a fuse base 10 (Fig. 1) comprising a casing ventilated at 25 carrying terminal blocks 12.
