Abstract
A method for operating a protective apparatus and a protective apparatus, in particular a self-tripping explosive fuse, wherein the protective apparatus includes a fuse element, which is designed to interrupt a conductor section by an explosion. A tripping unit is designed to trip the explosion by an ignition voltage (U) when the ignition voltage exceeds a prescribed value. The protective apparatus has a thermoelectric element, which generates the ignition voltage (U) depending on heating of the conductor section.
