A modular switching device is disclosed which includes a plurality of interconnected modules, the modules having a control device module and a pole cell module, the modules of the switching device being interconnected with a shaft adapted to transfer a torque required for operating the switching device from one module to another module. The modular switching device is configured such that each module has a shaft element, and the shaft transferring the torque is composed of directly interconnected shaft elements.

Modular switching device

A switching device module comprising a frame (), the switching device module being adapted to be connected to another switching device module for providing a modular switching device. The frame () of the switching device module is provided with one or more wire troughs (), each of which is adapted to receive at least one wire of an auxiliary circuit of said modular switching device.

Switching device module

A switching device is disclosed which includes a frame, a first connector and a second connector, the first connector and the second connector extending from inside the frame outside the frame. The first and the second connector are electrically connected to one another, and one or more gas flow openings are provided in the frame and arranged for a gas flow produced by a switching event. In its portion remaining inside the frame, the first connector includes a hole provided for said gas flow.
