Abstract: A fuse holder (20) is provided that can be used to replace a dropout fuse element in an insulator and that can accommodate the removed dropout fuse element. The fuse holder (20) has an electrically insulating body providing at least one electrically insulated elongate fuse passage (21) associated with the body and adapted to receive a fuse wire (22) held under tension therein and to drop out if the fuse is blown. A dropout fuse element is installed between co-operant mating contact means (26, 27) on the body and switch means (29, 31, 32) are adapted to automatically close, in use, when the fuse element drops out in consequence of its fuse being blown. The switch means (29, 31, 32) is biased to its closed position and is held open against such bias by a catch (41) associated with a release arm (42) located to be moved to disengage the catch (41) by motion of a dropout fuse element dropping out of its operative position after its fuse has blown.
