Three-phase bidirectional indirect, semi-indirect, m-bus, 100(5)A, MID LE-03MB-CT meter

Three-phase energy meter with M-Bus communication

This advanced three-phase energy meter, designed for indirect or semi-indirect measurement, offers precise and reliable energy consumption measurement in electrical installations. Equipped with an M-Bus communication interface, it enables remote data reading and integration with energy consumption monitoring systems. It is an ideal solution for both professional installers and end-users looking for accurate energy billing.

The LE-03MB-CT meter is designed to work with current transformers (1A or 5A) and voltage transformers, providing flexibility in adapting to different network configurations. Its compact housing with a width of 4 modules simplifies mounting on a DIN rail, and the MID certificate guarantees compliance with applicable standards and device legalization.

Functionality and application

The meter measures both active and reactive energy in three-phase networks, and also monitors key parameters such as voltage, current, active and reactive power, power factor and frequency. It provides bidirectional energy measurement, allowing registration of both imported and exported energy. The anti-tamper function and password protection for configuration access increase data security and integrity.

Thanks to the S0 pulse output (configurable pulses per kWh/kvarh), the meter can be easily integrated with building automation systems and remote data reading systems. The MeternetPRO software (available separately) enables remote reading of meter states and data analysis in the Excel environment.

Construction and parameters

The device is characterized by a solid construction and high quality workmanship. It has a digital LCD display with backlight, which facilitates reading measured values even in low light conditions. Accuracy class B ensures precise measurements, and a wide range of rated voltages (230…400 V) and rated currents (5 A) allows the meter to be used in various electrical installations. Protection class IP20 provides protection against touch and dust.
