Abstract: An electrical disconnect includes a housing having a recess defined therein extending from an opening toward a base. The disconnect also includes a vacuum envelope defined within the housing near the base; a fixed contact assembly including a fixed contact structured to be in electrical communication with a voltage source disposed partially within the vacuum envelope; and a movable contact assembly including a movable contact having a first end disposed within the vacuum envelope and a second end disposed in the recess near the base and movable between a closed position in electrical contact with the fixed contact and an open position spaced apart from the fixed contact a separation distance. The housing includes a dynamic shield electrically connected to the movable contact, the dynamic shield being disposed about the recess within the housing and extending from the base toward the opening thereof.
