ABSTRACT:
An electric power interrupter with an internal contactor that is suitable for use as a line and load switch constructed from light weight materials including a fiberglass or composite insulator and aluminum flanges. The light weight design feature allows the power interrupter to be supported above a standard disconnect switch insulator without having to replace or reinforce the insulator. The power interrupter also includes a latch mechanism with a low-force trip action, such as a spring-driven toggle mechanism that accelerates the internal contactor to break the electric power circuit on the opening stroke. This low-force trip action allows the power interrupter to be actuated by a standard disconnect switch operating mechanism without having to upgrade or augment the standard operating mechanism. For these reasons, the power interrupter may be installed as a retrofit upgrade to an existing standard disconnect switch without having to modify the underlying disconnect switch.
