Three-phase active and reactive energy meter, m-bus, 100(5)A, MID LE-03MB

Three-phase energy meter – precise measurement and reliable communication

This three-phase electricity consumption meter, catalog number LE-03MB, is an advanced device designed to measure both active and reactive energy. Designed for precision and reliability, it is perfect for both industrial and commercial installations. Thanks to the M-bus interface, it enables remote data reading and integration with energy consumption monitoring systems.

Functionality and application

The LE-03MB meter is designed for direct measurement in three-phase circuits (including the neutral wire). Its design allows for mounting on a DIN rail, which facilitates installation and servicing. The device measures energy drawn from and delivered to the grid, which is particularly important in installations with renewable energy sources or cogeneration systems. The meter's anti-tamper feature ensures the integrity of the measurement data.

This meter is used in:

• Commercial buildings: offices, shopping centers, warehouses – anywhere where accurate energy consumption measurement is required.
• Industrial installations: production plants, workshops – monitoring energy consumption to optimize costs.
• Renewable energy systems: measuring energy production and consumption in photovoltaic or wind installations.
• Applications requiring remote reading: integration with energy management systems (EMS) via the M-bus interface.

Construction features and operating parameters

The LE-03MB meter is characterized by high measurement accuracy (class B) and a wide range of rated voltages (230…400 V) and rated currents (5 A). It has a MID (Measuring Instruments Directive) certificate, which confirms its compliance with European metrological standards and guarantees the legality of measurements. The IP20 protection class provides protection against accidental contact. The S0 type pulse output allows easy integration with external data logging systems – the number of pulses is configurable in the range of 0.01…100 Imp/kWh (kvarh). The meter's width is 4.5 modules, allowing for convenient placement in a distribution board. A single-rate billing method simplifies device operation.
