## Summary description

Three-phase electric energy meter FF LE-03MW-CT designed to measure active energy in three-phase electrical installations. The meter is suitable for monitoring consumption in commercial or industrial environments and for integration with systems using current transformers (CT). It provides accurate energy measurement for load balancing, billing and consumption analysis.

## Long description

The FF LE-03MW-CT three-phase electric energy meter is designed to measure active energy in three-phase electrical installations where measurement via external current transformers (CT) is required. It provides metering suitable for commercial and industrial environments, enabling monitoring of consumption, load balancing and data collection for billing or energy analysis. The compact panel-mount enclosure and clear display make it practical for integration into switchboards and energy management systems.
Advantages
The meter supports three-phase measurement with external CT inputs, delivering accurate active energy readings across a wide range of loads. Its design allows installation in industrial or commercial switchgear with secure connections for current transformers and voltage inputs. The meter presents measured values on a readable front display and is compatible with systems that require reliable consumption data for billing, reporting and energy efficiency assessments.
Suitable for
Monitoring energy consumption in commercial buildings and retail outlets
Measuring active energy in industrial plants and production lines
Installation in distribution panels using current transformers for higher currents
Integration with energy management systems for load balancing and billing
Key specifications
Measurement type: Active energy (three-phase)
Input method: External current transformers (CT) for current measurement
Voltage measurement: Three-phase voltage inputs compatible with standard low-voltage networks
Display: Front-mounted readable display for energy values
Mounting: Panel or switchboard installation
Use environment: Commercial and industrial applications
How to use
Install the meter in a panel or switchboard following local electrical codes and ensure the panel is de-energized before making connections. Connect the three-phase voltage inputs to the appropriate line terminals and wire the secondary side of the selected current transformers to the meter’s CT input terminals, observing correct polarity and phasing. After powering the circuit, verify the display shows expected voltage and energy readings and confirm correct CT ratios in any connected monitoring system. Periodic verification against reference measurements is recommended to ensure ongoing accuracy.
Usage recommendations
Select current transformers with appropriate primary/secondary ratios and accuracy class for the expected current range. Ensure proper toroidal or clamp CT placement to avoid measurement errors. Follow manufacturer guidance and local regulations for installation, grounding and safety. For billing or contractual measurements, arrange periodic calibration and verification by qualified personnel.
