Closing Operation of Load Switch
Insert the operating handle into the closing shaft hole (bottom right), and rotate it clockwise by 180°. The mechanism drives the contacts to complete rapid closing of the load switch. Meanwhile, the spring is charged for opening.
To open the load switch, press the opening button to release the energy of the opening spring via the trip catch. The mechanism drives the main shaft to complete rapid opening.
Earthing Operation of Load Switch
The earthing operation of CT-□C (A-type) spring operating mechanism is the same as that of CT-□C (K-type) spring operating mechanism.
Notes:
The outgoing spring operating mechanism is equipped with fuse trip and manual opening button, and can be fitted with a shunt trip coil as an option.
When ordering a motor spring operating mechanism, please specify the voltage level (e.g. DC220V, DC110V, DC48V, DC24V for A-type motor operating mechanism).
If a shunt release is required, please state it in the order and mark its voltage level (e.g. DC220V, DC110V, DC48V, DC24V). If not specified, the voltage shall be the same as that of the motor of the motor operating mechanism.
