Abstract
The disclosed concept relates to vacuum interrupters having an electrically floating arc-enduring center shield component made out of an alloy of copper (Cu) and chromium (Cr), with or without additional minority alloying element or elements, and contact assemblies positioned in a vacuum envelope. In an open position, the contact assemblies include a contact gap formed there between. In accordance with the invention, contact assemblies are axially positioned such that the axial position of the contact gap aligns with a portion of the wall of the Cu—Cr alloy-based center shield component that has a maximum thickness and outer diameter.
