Abstract: A device for thermionic arc extinction via anode ion depletion. The device includes a body including an inner compartment. The inner compartment includes at least an arc shield housing at least two arcing contacts, wherein the two arcing contacts are zinc-plated. The at least two zinc-plated arcing contacts further comprise a thickness and contact area customized based on a desired corrosion time of the zinc, wherein the corrosion time corresponds to extinction of the arc. A sensor is associated with the device. The sensor is configured to operate the movement of the at least two arcing contacts.
