Manual operating mechanisms allow for manual operation of any COELME-EGIC disconnector and, upon request, they can also be easily adapted to equipment from other manufacturers.

Different models are available. The main are:

CM102 and CM113, for the operation of disconnectors without earthing blades (with a lever, acting directly on the vertical driving shaft, and by means of a crank to be inserted into a reduction gear located inside the box, respectively);
CM202 and CM213, for the operation of disconnectors provided with earthing blades (with a lever, acting directly on the vertical driving shafts, and by means of two cranks, each to be inserted into its own reduction gear located inside the box, respectively).

The CM102 and the CM113 are provided with one output shaft (to be connected to the disconnector transmission system), whereas models CM202 and CM213 can count on two output shafts coming from the same box (one to be connected to the disconnector transmission system, the other to the transmission system of the associated earthing switch): thanks to this configuration the mechanical interlock between the disconnector and the earthing switch is located in the optimal position, i.e. as close to power sources as possible, thus making the device robust and fully reliable, which is fundamental both for the device itself and the safety of the staff operating it.

All models are extremely versatile, which allows implementing any electric diagrams quite easily as well as meeting all possible specifications.
