Circuit breaker

A circuit breaker comprising:

• a cradle having an accommodation space therein and a plurality of terminals;
• and
• a breaker main body having a plurality of terminal connectors and a plurality of vacuum interrupters, each of the plurality of terminal connectors contactable with one of the plurality of terminals and each of the plurality of vacuum interrupters connected to one of the plurality of terminal connectors, the breaker main body installed within the cradle such that the breaker main body is movable between a connected position in which the plurality of terminal connectors are connected to the plurality of terminals and a disconnected position in which the plurality of terminal connectors are separated from the plurality of terminals,
• wherein each of the plurality of terminal connectors comprises:
• a plurality of segment conductors each having one end connected to the corresponding vacuum interrupter and the other end facing the corresponding terminal;
• a contact member connected to the other end of each of the plurality of segment conductors to allow for current flow and connected to the corresponding terminal at a connected position of the breaker main body;
• and
• a coupling conductor simultaneously coupled to the other end of the plurality of segment conductors and having a periphery coupled with the contact member, and
• wherein each coupling conductor comprises a body and a plurality of coupling portions formed on one side of the body for connection to an end portion of each of the plurality of corresponding segment conductors.
