Abstract:
1. A medium voltage vacuum circuit interrupter comprising: a first terminal; a second terminal; a vacuum switch comprising a vacuum envelope containing a fixed contact assembly and a movable contact assembly movable between a closed circuit position in electrical communication with the fixed contact assembly and an open circuit position spaced apart from the fixed contact assembly, said fixed contact assembly electrically interconnected with said first terminal; a flexible conductor electrically connecting said movable contact assembly with said second terminal; an operating mechanism moving said movable contact assembly between the closed circuit position and the open circuit position; an elongated housing including a first end supporting said first terminal and an opposite second end supporting said second terminal, said housing enclosing said vacuum switch, said flexible conductor and said operating mechanism; wherein said operating mechanism includes a current sensor sensing current passing between said movable contact assembly and said second terminal, and a trip unit responsive to said sensed current to move said movable contact assembly from the closed circuit position to the open circuit position; and wherein said elongated housing has an opening; and wherein said trip unit includes a wireless communication port, which protrudes through the opening of said housing.
