Abstract

A vacuum-type circuit breaker comprises a plurality of vacuum circuit interrupters stacked one above the other and electrically connected in series. For mounting the interrupters, a pair of horizontally-spaced, vertically-extending channels of insulating material are provided. Extending horizontally between the webs of the channels are a plurality of interrupter-supporting plates, to which the interrupters are respectively secured. Each of these plates is detachably connected to the webs and, when detached, is removable laterally of the channels from the space between the webs to permit the plate together with its associated interrupter to be removed from the circuit breaker.
