Energy meter with CT measurement, 3-phase 5A with RS485 output, 2 tariffs 412043

Intelligent Energy Measurement for Demanding Installations

This three-phase Legrand energy meter, designed for current transformer (CT) measurement, is an advanced solution for both professional installers and end users. The device offers precise energy consumption measurement in 3-phase systems, while the RS485 interface enables easy integration with energy monitoring and management systems. Two independent tariffs allow for energy cost optimization by billing consumption across different time zones or for different consumers.

The meter complies with the MID Directive, ensuring its legal metrological approval and suitability for commercial billing. Robust construction and high accuracy class (B) guarantee reliable long-term operation. DIN rail mounting simplifies installation in electrical distribution boards.

Functionality and Applications

The device measures both active and reactive power, providing a complete picture of energy consumption. Its capability to measure import/export makes it ideal for applications involving energy recovery or generation from renewable sources. Thanks to its wide range of rated voltages (197-265V N-L and 340-460V L-L) and rated currents (5A), the meter is compatible with diverse electrical installations.

The RS-485 interface enables remote data reading and meter configuration, significantly simplifying energy management in commercial and industrial buildings. The possibility of blocking reverse meter rotation and password protection enhance security and prevent unauthorized access to data.

Design Features and Specifications

The meter features a compact design with a width of 4 modules, allowing space savings in the distribution board. An IP54 protection rating ensures resistance to dust and moisture, enabling installation in various environmental conditions. The durable enclosure made from high-quality materials guarantees long-term device reliability. Additionally, the absence of a pulse output simplifies the design and reduces costs while maintaining high basic functionality – precise electrical energy measurement.
