Beschreibung
Zusammenfassung:	The invention relates to an electrical fuse (1), comprising: an electro-pyrotechnic igniter (2); a separating element (3), which can be moved by means of the electro-pyrotechnic igniter (2); and a busbar (4) with a separating section (5), wherein the separating element (3) is arranged in such a manner that the separating element (3) can move after the electro-pyrotechnic igniter (2) is triggered and, in this way, can separate the busbar (4) in the separating section (5); and at least one inductive coupling means (6) arranged on the busbar (4) or a high-voltage line (20). The electrical fuse further comprises a control circuit (8) for controlling an ignition current (15) for triggering the electro-pyrotechnic igniter (2), wherein the control circuit (8) comprises at least one semiconductor switch (9) for switching the ignition current (15) provided, at least one capacitor (10) connected to a control input (13) of the semiconductor switch (9), and a diode (12), with the diode (12) being connected on one side to
