ABSTRACT:
A novel fuse arrangement for electrical and electronic circuits is provided having shorter arcing time and arc-extinguishing time as compared to the prior art fuses. The fuse arrangement described herein comprises a pair of electrodes having contact terminals for connection to the circuit and a support member preferably disposed triangularly relative to the electrodes. In one embodiment, a fusible wire elment is stretched between the electrodes and has its mid portion supported by the support member. The support member is made from a material of large heat capacity and high thermal conductivity to provide a heat dissipating surface for the heat generated in the fusible wire element.
