ABSTRACT:
A fuse holder assembly (1) is provided having at least two electrically insulated fuse housings in the form of passages (5, 33) associated with the body and each of which is adapted to receive a fuse (6) held under tension therein by means of an elongate tension member (7) and cooperating spring loaded tensioning element. The fuse housings have separate intermediate contacts (16, 17, 34, 35) at one end adapted for sequential connection to a circuit contact (20) by way of a rotatable conductive arm (18, 37) spring loaded to effect rotation of the arm from one intermediate contact to the other. Stop means (22, 23, 36 39) for temporarily maintaining the arm in association with one intermediate contact against the spring loading of the arm acts to release the arm for movement towards a subsequent intermediate contact only when the spring loaded tensioning element has substantially reached the end of its operative movement to clear the blown fuse.
