Patent ID: 7012498

Claim:
A fuse holder assembly comprising a body providing at least two electrically insulated fuse housings in the form of passages associated with the body and each adapted to receive a fuse held under tension therein by means of an elongate tension member, wherein the fuse housings have electrical contact means connected together at one end to a common first circuit contact for connecting one end of each fuse assembly into a circuit and at the other end with separate intermediate contacts adapted for sequential connection to a second circuit contact by way of a rotatable conductive arm spring loaded to effect rotation of the arm from one intermediate contact to the other; stop means for temporarily maintaining the arm in association with one intermediate contact against the spring loading thereof wherein the stop means is releasable to allow the arm to rotate to a following intermediate contact after the fuse associated with the particular intermediate contact with which the arm communicates has blown; a tensioning device associated with each passage at an end thereof corresponding to the intermediate contacts and comprising a spring loaded tensioning element for engaging the tension member associated with the fuse and adapted to move the tension member in a direction outwards of the associated passage in the event of the associated fuse being blown; wherein the stop means and spring loaded tensioning element are arranged such that the stop means only releases the arm for movement towards the subsequent intermediate contact when the spring loaded tensioning element has substantially reached the end of its operative movement to clear the blown fuse.
