Vacuum circuit breaker

A vacuum circuit breaker comprising:

• an electric conduction pole electrically connected to an external power source or a load;
• and
• a temperature detection sensor disposed adjacent to the electric conduction pole,
• wherein the electric conduction pole comprises:
• a plate part provided to have a plate shape;
• and
• an electric conduction pole terminal provided to have a column shape extending in one direction and having one end coupled to the plate part, and
• the temperature detection sensor comprises:
• a sensor body arranged adjacent to one side of the plate part and having an input unit accommodated therein;
• a fixing terminal which is in contact with a specific point of the electric conduction pole and configured to measure temperature of the specific point;
• and
• a connection line positioned in the electric conduction pole terminal, and having one end coupled to the sensor body and another end coupled to the fixing terminal.
