Three-phase electricity meter, 125A 6M, Modbus, MID ECR310D

Three-phase energy meter – precise measurement and remote reading

This three-phase energy meter, with a maximum current of 125A, is a reliable solution for both installers and end-users. It provides accurate energy consumption measurement, and thanks to the Modbus interface, it enables remote data reading and integration with monitoring systems. It meets MID requirements, which guarantees legalization and measurement reliability. A width of 6 modules simplifies installation in standard distribution boards.

Features and application

The meter is designed to measure electrical energy in three-phase installations with a neutral wire. Thanks to the ability to measure both energy consumption and return, it is ideal for systems with renewable energy sources (RES), such as photovoltaics. The pulse output allows data logging in building automation systems or remote reading systems. Accuracy class B ensures precise measurements, and the meter's anti-tamper lock protects against manipulation.

• Versatility: Suitable for use in residential, commercial and industrial buildings.
• Remote reading: Modbus interface enables integration with energy consumption monitoring systems.
• Legalization: Compliance with MID requirements guarantees measurement reliability and compliance with regulations.
• Anti-tamper protection: Meter's anti-tamper lock ensures data integrity.
• Multi-tariff support: Support for multiple tariffs allows for energy cost optimization.
• Direct measurement: Model designed for direct connection to the electrical installation, without the need for current transformers (in most cases).

Technical parameters and construction

The meter is made of high-quality materials, ensuring its durability and reliability. Installation is done on a standard 35mm DIN rail, which simplifies installation. A width of 6 modules allows for efficient use of space in the distribution board. The housing with a protection degree of IP20 protects against touch and dust. The range of rated voltages L-L (160-480V) and L-N (92-276V) makes the meter compatible with various electrical installations. The optical pulse output allows easy connection to external systems.

The meter is characterized by a maximum current of 125A, a rated voltage L-L in the range of 160-480V and a rated voltage L-N in the range of 92-276V. The accuracy class is B, and the communication interface is Modbus. It is equipped with an optical pulse output, has a width of 6 modules, a protection degree of IP20 and has MID legalization.

The meter has a wide frequency range (45-65 Hz), which ensures its stable operation in various network conditions. Power consumption at 2 VA minimizes the impact on the energy efficiency of the installation. The device is designed to operate at a temperature of -25°C to +55°C, making it suitable for indoor use in most environments.
