Each arcing chamber has a hinged contact bridge cooperating with a stationary contact arrangement. An interrupter shaft common to the poles of the multipole circuit breaker and including a number of shaft segments made of an insulating material, in each of which a contact bridge is arranged, is provided. The adjoining shaft segments are joined to each other by a respective coupling element, each coupling element including two tab-shaped parts joined to each other by a support shaft. Each tab-shaped part supports at least two first connecting pins on a side facing away from the support shaft and extending in an axial direction. The shaft segments each include recesses a side facing the coupling element, the recesses for receiving the connecting pins. A support, or bearing, for supporting the support shaft is provided in the arcing chamber housing in a transition area between adjacent arcing chambers.
