FN3-12 Series Indoor Load Break Switch
Product Overview:
The FN3-12 Series Indoor Load Break Switch, including the FN3-12, FN3-12R, and FN3-12R/S models, is designed for use in AC networks with a frequency of 50Hz and voltage levels ranging from 6kV to 12kV. This switch is specifically engineered to break or switch on-load and overload currents, as well as to manage no-load equipment switching. The FN3-12R and FN3-12R/S models, when combined with the RN3 Fuse, can safely interrupt short-circuit currents, thereby providing robust protection for the switch itself. These switches can be equipped with either the CS3 or CS2 handle as the operating mechanism.
Application Environment:
The FN3-12 series is primarily utilized in indoor medium voltage power distribution systems, often found in industrial, commercial, and utility sectors. These switches are essential for ensuring reliable operation in environments where secure and efficient load management is critical. They are suitable for installation in compact spaces and are designed to function optimally in controlled indoor environments.
Operating Conditions:
1. Temperature Range: The switch is designed to operate effectively in environments with temperatures ranging from -5°C to +40°C.
2. Altitude: Suitable for use at altitudes not exceeding 1000 meters above sea level.
3. Humidity: Designed for operation in areas where the relative humidity does not exceed 90%.
4. Pollution Level: Applicable in environments with pollution levels up to class II.
Usage Considerations:
1. Voltage and Current Handling: The switch is capable of handling both load and overload currents in 6kV to 12kV networks, ensuring safe operation during switching events.
2. Short-Circuit Protection: The FN3-12R and FN3-12R/S models, when paired with RN3 fuses, offer enhanced protection by safely breaking short-circuit currents, preventing potential damage to the switch and associated equipment.
3. Routine Maintenance: Regular inspections are recommended to ensure the operating mechanism and contacts are functioning correctly and to maintain the integrity of the insulation.
4. Operational Safety: Operators should be well-trained in the proper use of the switch, particularly in understanding the limitations of load and overload switching to prevent unnecessary wear or damage.
Key Features:
• Versatility: The FN3-12 series offers a range of models to suit different load and overload switching needs, with the option for fuse integration for enhanced short-circuit protection.
• Compact Design: Ideal for indoor installations where space is limited and efficient load management is required.
• Reliable Operation: The robust design and quality construction ensure long-term reliability and safety in medium voltage distribution systems.
