    Abstract: Some embodiments include a fuse element assembly having a first portion configured to rupture as materials of the first portion flow to a second portion through electromigration. The assembly has a second portion configured to accumulate the materials that have flowed from the first portion. The assembly also has a control element configured to divide the flow of materials into at least two paths along the second portion. The first portion may be a fuse-link and the second portion may be a cathode coupled to the fuse-link through a narrow neck region. The control element may be, for example, a slit, a hole, a conductive contact, etc.

    Abstract: An electric component includes a first base body that connects to a first contact, and an ally conducting element positioned along a current path between the first contact and a second contact. The electrically conducting element melts when an operating voltage of the electric component is exceeded. The electric component also includes an electrically insulating material that substantially surrounds the electrically conducting element and that is arranged so as to prevent an electric flashover between regions of the current path that are bridged by the electrically conducting element.

    Abstract: The invention relates to a method for producing a protective component, for example a fuse component or a fusing resistor, including a fusible element and a heating element, which are attached as stacking components to the surface of a substrate. The fusible element is configured in such a way that a current flow between its connections is interrupted, if the fusible component is heated, at least in one fusible region, for a predetermined time period to above a predetermined temperature. The fusible element and the heating element are arranged on the substrate in such a way, that heat created by the heating element is transported to the fusible element and the current flow through the heating element exceeds a threshold value for a predetermined time period. During production, the heating element is positioned next to the fusible element, at a predetermined distance from it. A predetermined, local thermal capacitance is set, at least approximately, at the location of the heating element and is coupled to the latter. Alternatively, a predetermined, local thermal capacitance is set at least at one predetermined location between the heating element and the fusible element. The capacitance accumulates part of the heat that is dissipated from the heating element to the fusible element. This produces, at least approximately, a defined time response of the thermal transmission from the heating element to the fusible element.

    Abstract: The fuseholder includes a current limiting fuse mounted within a fuse body and a lower contact and hinge assembly. The fuse body has contact assemblies mounted on each end thereof. The lower contact assembly on the fuse body is mounted on a hinge which is rotatably supported on an interchangeable cutout mounting. The current limiting fuse includes a fuse element spirally wound around a spider which extends the length of the fuse body. The fuse element includes a high current fusible element and a low current fuse element. The fusible element includes a plurality of spaced reduced areas and is supported on the spider by support surfaces which are located between adjacent reduced areas of the fusible element. An auxiliary wire also extends the length of the fuse body about the spider. The hinge includes a hinge member rotatably mounted on the interchangeable cutout mounting, a connective member supporting the contact assemblies and fuse body with current limiting fuse, and a latch for latching the hinge member to the connective member in a contracted position. The latch is connected to a trigger wire attached to the lower end of the auxiliary wire to maintain the hinge and connective members in their contracted position. Upon the melting of the trigger wire due to a current overload, the trigger wire releases the latch thereby allowing the connective member to move to an extended position with respect to the hinge member such that the current limiting fuse drops out of the interchangeable cutout mounting.

    Abstract: The invention relates to a circuit arrangement (12) for monitoring and triggering an igniter (5) of an active electrical fuse (6). The arrangement comprises: a control and evaluation unit (1), an alternating current generating unit (2) activated by the control and evaluation unit (1), an alternating current transmission unit arranged between the igniter (5) and the alternating current generating unit (2), the control and evaluation unit (1) being designed and programmed, in a first operational state, to determine the electrical resistance of the igniter (5) from a current detected on the primary side and a voltage detected on the primary side, the value of the resistance being a measure for tripping of the igniter (5), and, in a second operational state, to trigger the igniter (5) by means of the alternating current generating unit (2). The invention further relates to an associated method, to a computer program product which carries out the method and a computer-readable medium, and to a converter and to an aircraft having such a circuit arrangement.
