Abstract (en)
[origin: EP2306482A1] The present invention is to provide a main circuit terminal assembly for a vacuum circuit breaker, which can prevent temperature increase by increasing a surface area of a main circuit conductive unit, the main circuit terminal assembly for a vacuum circuit breaker which is electrically connected to a vacuum interrupter, including: a clamp electrically connected to a movable unit of the vacuum interrupter, and configured as a pair of conductors so as to support the movable unit by clamping; a heat sink fixed to the clamp that increase a surface area of the clamp; a flexible shunt having one end thereof electrically and mechanically connected to the clamp, and configured as a flexible conductor to allow the movable unit to move; a terminal block electrically and mechanically connected to another end of the flexible shunt, and configured as an electrical conductor; and a contactor unit electrically connected to the terminal block and having a plurality of clip-shaped contactors.
