More Information
Summary:A connection system for connecting electrical devices to busses within a switchgear cabinet includes an independently movable shutter that slides along a bus bar, the shutter covering access to the bus bar in a disconnected position and allowing access in a connected position. The bus bar has an insulator cap covering its free end. The shutter is mounted to a spring-biased support. The shutter has an opening through which the bus bar passes. The shutter slides along the bus bar backwardly away from the insulator cap, in the connected position. The shutter slides forwardly along the bus bar toward the insulator cap, in the disconnected position. The insulator cap fits closely within the opening in the shutter to prevent access to the bus bar when in the disconnected position. The shutter can fit within arc attenuating phase barriers surrounding each bus bar and be constructed to be arc resistant.
