Abstract
A circuit breaker according to the present disclosure includes a cradle having an accommodation space therein, the cradle having a plurality of terminals and a breaker main body having a plurality of terminal connectors contactable with the terminals, respectively, and a plurality of vacuum interrupters connected to the terminal connectors, respectively, the breaker main body being installed within the cradle to be movable between a connected position where the terminal connectors are connected to the terminals and a disconnected position where the terminal connectors are separated from the terminals. Each of the terminal connectors includes a plurality of segment conductors each having one end connected to the vacuum interrupter and the other end facing the terminal. According to the configuration, an amount of heat radiated may increase without an increase in an amount of copper used, thereby facilitating for cooling the terminal connectors.
