PROBLEM TO BE SOLVED: To provide a DC breaker capable of simplifying a circuit structure and having a current limiting function. SOLUTION: The DC breaker includes an ultra-low temperature-controlled oven 11 filled with liquid nitrogen, a breaking switch 13 dipped in the liquid nitrogen 12 of the ultra-low temperature-controlled oven 11, and a bushing 16 pulling up a transmission line for transmitting opening and closing instructions to a primary conductor 15 connected with the breaking switch 13 and the breaking switch 13 from the ultra-low temperature-controlled oven 11.
