An electrical fuse that includes an electro-pyrotechnic igniter, a separating element, which can be moved by the electro-pyrotechnic igniter, and a busbar with a separating section. A separating element is arranged so that it can move after the electro-pyrotechnic igniter is triggered to separate the busbar. At least one inductive coupler is arranged on the busbar or a high-voltage line. The electrical fuse further includes a control circuit for controlling an ignition current for triggering the electro-pyrotechnic igniter. The control circuit includes at least one semiconductor switch for switching the ignition current provided, at least one capacitor, connected to a control input of the semiconductor switch, and a diode coupled on one side to the at least one inductive coupler and on the other side to the capacitor and a control input of the semiconductor switch.
