Switch

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 fuse holder is disclosed which includes a frame, spring and a limiter,the frame having a first contact member and a second contact member adapted to receive an end of the fuse between them, the spring being adapted to press the contact member against the fuse end, and the limiter being adapted to define the largest possible depth of the fuse end in the installation direction between the first and second contact members. The spring includes a substantially circular arch-formed ring spring adapted to also serve as the limiter.
