Claim:
1. A redundant disconnection system for use in an electrical circuit, the system comprising: a switch; a resistive metallic fuse connected within the electrical circuit in series with the switch; an inductor comprising a coil of at least one turn of wire about a longitudinal axis; and an AC power source configured to provide an alternating current through the inductor; wherein the resistive metallic fuse is disposed within the inductor along the longitudinal axis, and the AC power source is configured to cause the inductor to induce eddy currents within the resistive metallic fuse, the eddy currents having a root mean square amplitude greater than the root mean square amplitude of the alternating current through the inductor and being of sufficient magnitude to melt or vaporize at least a portion of the resistive metallic fuse disposed therein.
