Abstract
A rotating arc circuit breaker comprising a pair of separable arcing contacts, a coil to set the arc in rotation, and an annular migration electrode. Guiding fins are arranged in the extinguishing chamber to slow down the rotation of the gas in a first peripheral zone, so as to generate a differential speed between the arc and the gas favoring the heat exchange in the second zone close to the breaking gap.
