Classification: CPC H  B | IPC B  H

Claim 13:
14. An electrical fuse, comprising:
an electro-pyrotechnical detonator;
a separating element configured to be moved by the electro-pyrotechnical detonator;
a busbar comprising a separating section, wherein the separating element is configured in relation to the electro-pyrotechnical detonator and the separating section in the busbar such that the separating element moves after the electro-pyrotechnical detonator is triggered to sever the busbar;
at least one inductive coupler configured on the busbar or a high voltage line; and
a control circuit for controlling a detonating current for triggering the electro-pyrotechnical detonator, wherein the control circuit comprises at least one semiconductor switch for switching the detonating current on, at least one capacitor coupled to a control input on the semiconductor switch, and a diode, wherein the diode is coupled at one side to the at least one inductive coupler, and at another side to the capacitor and the control input in the semiconductor switch,
wherein an inductance in the at least one inductive coupler is configured on the basis of (i) a minimum current supplied by a high voltage power source and flowing through the busbar, and/or (ii) an increase to the minimum current.
