Abstract
The invention discloses a vacuum contactor assembly for controlling current flow in a single or multi-phase electrical circuit wherein each phase of the electrical circuit is controlled by a single vacuum interrupter. The stem pressure or pressure exerted on the electrical contacts of each vacuum interrupter during and after closing may be individually adjusted to an optimum operating pressure. The individual interrupter stem pressure adjustment is accomplished by placing a spring and an adjustment nut on the stem screw between the operating arm and the interrupter stem. By adjusting the free length of the spring with the adjusting nut, the interrupter stem pressure may be controlled.
