Ordering Information (Must be specified when ordering)
1. Main circuit scheme number, purpose, single-line system diagram, arrangement diagram, and layout diagram of the distribution room.
2. Auxiliary circuit wiring diagram, terminal arrangement diagram.
3. Models, specifications, and quantities of electrical components inside the switchgear.
4. Requirements for control, measurement, and protection functions of the switchgear, as well as other interlocking and automatic device requirements.
5. If busbar bridges are required between switchgear or incoming cabinets, provide specific requirements such as the rated current, span, height above ground, etc., of the busbar bridge.
6. When accessories or spare parts are needed, specify the type and quantity.
7. If the switchgear is used in special environmental conditions, provide detailed information when ordering.
Structural Features
Power-On Operation (Maintenance– Run):
1. After completing maintenance, close the rear door, remove the key, and close the front door.
2. Move the small handle from the “Maintenance” position to the “Disconnection Lock” position. The front door is now locked, and
the circuit breaker cannot close.
3. Insert the operating handle into the grounding switch operation hole, pull down, and move to the disconnection position.
4. Remove the handle, insert it into the upper isolating switch operation hole, push up, and move to the upper connection position.
5. Remove the handle, insert it into the lower isolating switch operation hole, push up, and move to the lower connection position.
6. Remove the handle, move the small handle to the working position, and now the circuit breaker can be closed.
