Claim Text:
1. A circuit breaker designed for use with AC voltages greater than 30 kilovolts and AC currents greater than 400 amperes, the circuit breaker comprising: a main enclosure housing an interrupter that is electrically insulated from the main enclosure, wherein the interrupter is switchable between a closed state where first and second contacts of the interrupter are electrically connected defining a conductive path for current to flow between the first and second contacts and an open state where the first and second contacts of the interrupter are electrically isolated from each other; first and second electrically insulating bushings having proximal ends coupled to the main enclosure; first and second conductors disposed inside of the first and second bushings, wherein proximal ends of the first and second conductors are electrically connected to the first and second contacts of the interrupter defining a conductive path for current to flow between the first and second contacts and the first and second conductors, respectively; first and second terminal pads coupled between distal ends of the first and second bushings and distal ends of the first and second conductors disposed inside of the first and second bushings, respectively; and first and second extruded radiators coupled between the distal ends of the first and second bushings and the first and second terminal pads, respectively, wherein portions of the first and second conductors are disposed inside of the first and second extruded radiators.
