2. DESCRIPTION
Manual operating mechanisms type NR-5 are intended for cooperation with disconnectors, switch discon-
nectors and earthing switches of outdoor distribution network with rotary movement of the coupling/driving
shaft. Application of the operating mechanism enables local manual control of the apparatus. It is dedicated
for cooperation with every switch activated by a shaft placed along the supporting structure with a rotation
angle of up to 190 degrees, which torque does not exceed 300 Nm. It is possible to mount an additional cardan
module that allows the operating mechanism to work at an angle to the apparatus. The operating mechanism
is equipped with an auxiliary switch contact for control and signaling circuits as well as a manual blockade or
electromagnetic blockade ensuring the correct sequence of connections.
