3) QZR…FM device line extend the line. This device design has main advantage that whole drive can swivelled around 360° with minimum step 15°. The angular displacement of the drive mechanism can set depending the vertical mounting the switch disconnector the inside of the switching cell, with respect the control options the withdrawable insulated rod. This unit placed the right or on the left side the main devices frame.D0075. The client can order switch disconnector almost with any displacement angle the drive axis. This arrangement serves minimize the torque exerted the operating handle. These types of switch disconnectors, when operated manually emergency situations, need use the insulated rod of IMT 2. Everything minimised, also the main frame of device. The emergency manual operation using gear box output shaft, usually driven the electric motor, serves for switching the disconnector OFF and via the transmission gear including also transmission pre- stage.
