Motor operator for switchgear for mains power distribution systems

A motor operator for switchgear mains power distribution systems,

• said switchgear (1) comprising a closed cabinet (5) with an operating shaft (53) protruding there from, said operating shaft being rotable at least between two positions and has a coupling part (2),
• said motor operator (6,7) comprising a housing mountable in front of the switchgear cabinet, a rotatable connection shaft (51) connected to an electric motor via a drive mechanism, and has a first coupling part (52) to fit with the coupling part (2) of the switchgear in a non-rotational interlocking manner, and further has a second coupling part (54) accessible from outside of the housing to operate the switchgear manually and for which purpose the motor operator has a release mechanism releasing the connection shaft (51) from the electric motor for manually operations,
• wherein the motor and the drive mechanism comprise an electro-mechanical actuator with a rear mounting (23) for mounting the actuator in the housing of the motor operator and a front mounting (29) on an activation element (17) of the actuator for connection of the activation element to the rotatable connection shaft (51).
