Abstract
The invention relates to a fuse having an input connection (1), an output connection (2) and two parallel current paths which connect both connections to one another. The current paths are namely a main current path (3) and a partial current path. The electric fuse comprises a single fuse element (5) arranged in the main current path (3). In addition, a switch (6) which is arranged inthe partial current path is provided. The switch (6) is configured in such a way that it opens when given limiting values are exceeded, said limiting values pertaining to the current flowing through the fuse and/or to the temperture of the fuse element.
Claims19
An electric fuse having an input connection, an output connection, two parallel current paths, namely a main current path and a partial current path, which connect the two connections to one another, a single fusible element and a normally closed switch, with the single fusible element being disposed in the main current path and the switch being disposed in the partial current path, and with the switch being designed to open when at least one of predetermined limit values of the current flowing through the fuse, and the temperature of the fusible element, is exceeded.
An electric fuse having an input connection, an output connection, two parallel current paths, namely a main current path and a partial current path, which connect the two connections to one another, a single fusible element and a normally closed switch, with the single fusible element being disposed in the main current path and the switch being disposed in the partial current path, and means for directly detecting the temperature of the fusible element and for opening the switch when a predetermined limit value for the temperature of the fusible element is exceeded.
