Abstract: A multiple fuse device for a vehicle includes a circuit board with a battery-side bus bar portion and an alternator-side bus bar portion connected together by a temporary joint portion at a position apart from a fusing portion that provides charging current protection. An insulator housing is placed over the circuit board but the temporary joint portion is left uncovered by the insulator housing. A temporary joint portion is then at least partially removed.

Abstract: A high voltage current limiting fuse has improved low fault current interruption due to an end-sealed sleeve separating a fusible length from pulverulent sand in a casing of the fuse while permitting venting of gas and vaporized metal plasma due to melting and arcing at the fusible length. The fuse can have one or more fusible elements, of which at least one, preferably each one, is surrounded along at least a selected portion along its length by a polytetrafluoroethylene polymer, fluoroethylene polymer, or derivatives thereof, which can be heat shrinkable or not. The sleeve is sealed so as to allow escape of gases upon arcing from the sleeve but to prevent pulverulent materials from penetrating within the sleeve. The sleeve seals are either melted and crimped together with the fusible element, heat shrunk down onto the fusible element, or taped over the fusible element so as to leave a gap small enough to exclude the pulverulent material while venting gas and plasma.

Abstract: The dual element fuse of the present invention has at least one fusible element and at least one mass of heat softenable material; and that fusible element will respond to a short circuit to fuse and thereby assure opening of the circuit, whereas that mass of heat softenable material will respond to a long-continued relatively-low potentially-hurtful overcurrent to soften and thereby initiate opening of the circuit. That dual element fuse has a shunt element which shunts the mass of heat softenable material and which will fuse after that mass of heat softenable material has initiated opening of the circuit; and hence that shunt element will minimize arcing as that mass of heat softenable material initiates opening of the circuit.

Abstract: The fusible element of an electric fuse has a first electrical path, a second electrical path in parallel relation with the first electrical path, a weak spot in the first electrical path which can respond to a potentially-hurtful overcurrent to fuse and thereby form a first arc in the first electrical path, and a weak spot in the second electrical path longitudinally displaced from the weak spot in the first electrical path which can respond to that overcurrent to fuse and thereby form a first arc in the second electrical path. The weak spots form primary arcs as they fuse; and one important function of those primary arcs is to establish the point at which the rate of rise of the overcurrent starts to diminish, while another important function of those primary arcs is to burn the adjacent portions of the respective electrical conducting paths.
