## Long description

The FF LE-03 is a high-quality 3-phase electricity meter engineered for the precise measurement of active electrical energy in 230/400V AC systems. This device is built to handle a maximum current of 100A, making it a robust solution for monitoring power consumption in various electrical installations. Equipped with a traditional mechanical drum display, the meter offers excellent readability and reliability, ensuring that energy data remains visible even in environments where digital displays might be less practical. Its durable construction is designed for long-term operational stability in both residential and industrial settings.
Advantages
The primary benefit of the FF LE-03 is its mechanical drum display, which provides a clear and permanent reading of energy consumption without the need for an external power source to maintain the display. This design choice enhances the longevity of the device and ensures that data is preserved during power outages. Furthermore, the meter is built to withstand the demands of 3-phase electrical systems, offering consistent accuracy and reliable performance for sub-metering and energy management tasks. Its compact design allows for efficient installation in standard distribution boards, saving valuable space while providing essential monitoring capabilities.
Suitable for
Residential energy consumption monitoring
Industrial facility power usage tracking
Sub-metering in multi-tenant buildings
Energy management systems in commercial properties
When it may not be suitable
This device is not suitable for measuring reactive energy or for applications requiring advanced smart grid connectivity, such as remote data transmission or wireless monitoring. It is designed specifically for standard active energy measurement in 3-phase systems and does not support complex billing features or digital communication protocols.
Key specifications
Voltage: 230/400V AC
Maximum current: 100A
Phase type: 3-phase
Display type: Mechanical drum
Measurement type: Active energy
How to use
The FF LE-03 should be installed by a qualified electrician in accordance with local electrical regulations. The device is typically mounted on a standard DIN rail within an electrical distribution cabinet. Ensure that the input and output wiring is connected securely to the corresponding terminals as indicated on the device housing. Once installed, the mechanical drum display will begin to increment as electrical energy passes through the meter, providing a continuous and easy-to-read total of consumed power.
What to consider before purchase
Verify that your electrical system is a 3-phase 230/400V configuration
Ensure the maximum load does not exceed the 100A rating
Confirm that physical space is available on your DIN rail for installation
Check if your local regulations require a specific type of meter certification
Usage recommendations
Regularly inspect the installation for secure terminal connections to prevent overheating. Ensure the meter is protected from extreme moisture and dust to maintain the clarity of the mechanical display over time.
