ALEXANDRIA, Va., Aug. 25 -- United States Patent no. 12,718,992, issued on Aug. 25, was assigned to Siemens AG (Munich).
"Protective switching device and method" was invented by Marvin Tannhauser (Hausen, Germany).
According to the abstract* released by the U.S. Patent & Trademark Office: "A method for protecting an electrical low-voltage circuit for a protective switching device. A mechanical break contact unit, which is switched by opening or closing contacts for current flow in the low-voltage circuit, and an electronic interrupter, which is switched by semiconductor-based switching elements into a high-impedance state or a low-impedance state of the switching elements, are connected in series. If the level of current in the low-voltag...
