The vacuum circuit breaker contains a vacuum arc suppression chamber, inside which there are movable and fixed contacts connected to current leads, the movable contact is connected to a mechanical drive, and the contacts have working parts in the form of coaxially arranged conical surfaces with a hole in the center of the fixed contact. The fixed contact is connected to a housing made in the form of a metal cylinder closed at the ends with metal plates with a hole in one of them for the passage of the moving contact and connected to a mechanical drive. Outside the metal cylinder there is a coil connected to the current source. The body and the fixed contact are made with radial cuts along the entire height and placed inside the dielectric shell. The coil is connected to a pulse current source.
