Abstract
A medium voltage switching pole includes: a fixed contact of a vacuum interrupter; a movable contact of the vacuum interrupter; a piston; at least one electrical contact; a first terminal; and a second terminal. The fixed contact is fixedly connected to the first terminal. The movable contact is fixedly connected to the piston. The piston moves within the second terminal along an axis. The at least one electrical contact makes an electrical connection between the piston and the second terminal. An outer surface of the piston and an inner surface of the second terminal are arranged such that: when in an open configuration the fixed contact and movable contact are separated, at least one first radial line perpendicular to the axis extends through locations of the at least one electrical contact, and a first distance along the at least one first radial line extends from the outer surface.
