PROBLEM TO BE SOLVED: To provide a circuit breaker capable of easily achieving the duty to shut off, which is required for a high voltage circuit breaker and shortening the shut off time.SOLUTION: The circuit breaker includes: pressure vessels 1 and 2 filled with an electrical insulator; plural contact parts 7 and 9: an insulation spacer 3 that segments the pressure vessels 1 and 2 into the same number of contact parts to form internal spaces 101 and 102; and a spacer electrode 6 penetrating the insulation spacer 3 and is fixed to the insulation spacer 3. Each of the plural contact parts 7 and 9 has a contact and an operation section 29 that drives the contact. Each of the internal spaces 101 and 102 has a contact part. All contacts are electrically connected to each other in series via the spacer electrode 6. An operation section 29 drives the contacts. |
