Abstract

The present invention provides a medium voltage switchgear comprising per phase, two switches A,B, each switch comprising means for performing the disconnection function and means for performing the breaking function. This switchgear is characterized in that it comprises per phase, one single breaking system (2), said breaking system being adapted to be operated, independently relative to each other, by either one or the other of two mechanisms M,N, said mechanisms being operated respectively by said two switches A,B, said switches belonging respectively to two independent medium voltage power electrical circuits C1,C2.
