Abstract
A vacuum interrupter including a cylindrical insulator, a first end cap sealed to one end of the insulator and a second end cap sealed to an opposite end of the insulator to provide a vacuum chamber. The vacuum interrupter further includes a fixed contact stem extending through the first end cap and having a contact positioned within the chamber, and a movable contact stem extending through the second end cap and having a contact portion positioned within the chamber. A first vapor shield is formed around the fixed contact stem so as to define a gap between the fixed contact and the insulator and a second vapor shield is formed around the movable contact so as to define a gap between the movable contact and the insulator.
