Abstract
A motor operator for switchgear for use in mains power distribution systems comprising a closed cabinet (5) with an operating shaft (53) protruding there from said operating shaft being rotatable at least between two positions and has a coupling part (2). The motor operator (6, 7) comprises a housing mountable on the external surface of the switchgear cabinet. A rotatable connection shaft (51) is 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) extending from the housing to operate the contact of the switch manually and, for which purpose, the motor operator has a release mechanism releasing the connection shaft. The motor and the drive mechanism is designed as an electro-mechanical actuator with a rear mounting (23) for mounting the actuator in the housing of the motor operator and μ. front mounting (29) on the activation element (20) for connection of the activation element to the rotatable connection shaft (51).
