RH-B Series Outdoor Disconnecting Switch/LBS
Product Overview:
The FN7-12DR Type AC High Voltage Load Break Switch (LBS) is a new generation of indoor high-voltage load break switches designed for use in 3-phase AC power systems with a frequency of 50Hz and a rated voltage of 12kV. It serves to interrupt load currents and close circuits under short-circuit conditions, offering enhanced operational flexibility and improved safety features for modern power distribution networks.
Key Features:
• Advanced Switching Capability: The FN7-12DR is engineered to break load currents and safely handle short-circuit conditions, ensuring reliable protection and control in high-voltage power systems.
• Side Operation Actuator: This version builds upon the FN12 model by incorporating a side operation actuator, which simplifies the installation process and makes the switch easier to operate, catering to different customer requirements.
• Compact Design: With its streamlined design, the FN7-12DR takes up less space and can be easily integrated into various high-voltage switchgear panels, making it an ideal choice for compact installations.
• High Performance: The load break switch ensures reliable performance across a wide range of environmental conditions, with high short-circuit closing capability to protect other electrical equipment during faults.
• Enhanced Safety: The design of the FN7-12DR incorporates multiple interlocking and isolation mechanisms, ensuring safe operation under high-voltage conditions and preventing accidental operation.
Applications:
The FN7-12DR is ideal for use in:
• Indoor power distribution systems for industrial and utility sectors
• High-voltage switchgear panels in substations and power plants
• Load current interruption and short-circuit protection in AC distribution networks
Technical Specifications:
• Rated Voltage: 12kV
• Rated Frequency: 50Hz
• Rated Current: As per system requirements
• Short-Circuit Current: Capable of safely closing under short-circuit conditions
