An inductively compensated trigger conductor for use in a chemically augmented fuse, of the type in which current flow through the fuse generates a magnetic field, employs at least one loop of electrically conductive material to inductively couple the trigger conductor to the magnetic field of the fuse. This inductive coupling increases the electrical inductance of the trigger circuit, and allows the fuse to be constructed so that the current division between the fuse conductor and the trigger conductor is constantly proportional, or at least more nearly so. When employed in a fuse which also includes a non-magnetic fuse support structure, a trigger device, and a means for chemically augmenting the separation of the fuse conductor into more than one segment during current interruption, the trigger circuit of this invention provides triggering action which is responsive only to the level of current flowing through the fuse, and not to a high rate of rise of current.
