FGF-12 Earth switch (Ground switch)
Overview
The FGF-12 series Earth Switch (Ground Switch) is designed to provide a safe and reliable grounding function, suitable for use in high-voltage power systems. Its simple operation and rational structure allow it to be widely used in various electrical facilities, ensuring the safety of the system.
Operating Instructions
1.Disengaging the Earth Switch: Insert the operating handle into the earth switch operation hole and turn it counterclockwise to disengage. At this point, the open/close indicator on the panel center will display a star shape, and the lower panel will be locked, ensuring operational safety.
2.Engaging the Earth Switch: Insert the operating handle into the load switch operation hole and turn it clockwise (or press the closing button for electric operation) to engage the switch. The open/close indicator will then display the closed state, indicating that the switch is engaged.
3.Contact Types: When using fan-shaped contacts, the earth switch's grounding contacts are assembled at positions 1, 4, and 6. For copper bar overlaps, the grounding contacts are assembled at positions 2, 3, and 5. These different contact configurations meet various installation needs, ensuring flexibility and reliability in grounding operations.
Application Scenarios
The FGF-12 earth switch is suitable for grounding protection in various high-voltage power systems, providing safety during maintenance and fault handling of electrical equipment. Its simple and user-friendly design, coupled with high mechanical strength and durability, makes it ideal for long-term use.
