Estimating the term…
An object is to provide a gas circuit breaker having improved reliability. To solve the above-described problem, a gas circuit breaker is characterized by having a fixed contact, a movable contact configured to come into contact with or separate from the fixed contact, an insulating enclosure internally having the fixed contact and the movable contact, the inside of the insulating enclosure being filled with an insulating gas, and an operating mechanism configured to allow drive force for movement of the movable contact to be generated, wherein the operating mechanism includes a mover including permanent magnets or magnetic bodies disposed in a direction along which the operating mechanism allows the drive force to be generated, and a magnetic pole disposed to be opposed to the mover, and having a winding.
