Energy meter iEM3355 125 A Modbus MID A9MEM3355

Intelligent energy measurement for demanding installations

The iEM3355 energy meter is an advanced device designed for precise measurement of electricity consumption in three-phase networks. Mounted on a DIN rail, it offers a wide range of configuration and communication options, making it an ideal solution for both installers and end-users. Thanks to its compliance with the MID standard, this meter ensures measurement reliability, which is crucial in billing applications.

Functionality and technical parameters

This three-phase energy meter with a Modbus interface allows for remote data reading and integration with energy management systems. Equipped with a digital display, it presents key network parameters such as voltage, current, active and reactive power. Multi-tariff support with external or internal control allows for energy cost optimization. A maximum current of 125A enables use in installations with significant power consumption. Accuracy class B guarantees the precision of active energy measurements, and a rated voltage range of 100…277 V / 173…480 V ensures compatibility with various power grids. Additionally, a D0 type pulse output enables external systems to record energy consumption.

• Versatility: Measurement of active and reactive power and active and reactive energy in 50/60 Hz networks.
• Communication: Modbus interface enables integration with monitoring and remote data reading systems.
• Accuracy: Accuracy class B ensures reliable active energy measurements.
• Tariff flexibility: Multi-tariff support with external or internal control allows for energy cost optimization.
• Safety: Compliance with the MID standard guarantees measurement legalization (no counter-rollback lock).
• Compact size: Width of 7 modules (126 mm) facilitates mounting in electrical panels with limited space.
• Durability: Protection class IP20 provides protection against touch and dust.

Application and installation

The iEM3355 meter is used in commercial buildings, industrial plants, and residential installations requiring precise energy consumption monitoring. Installation is done via an adapter on a DIN rail, which greatly simplifies installation and device replacement. Thanks to its compact dimensions (126 x 103.2 x 69.3 mm), the meter can be easily mounted even in tight electrical panels. The device is designed for direct current measurement up to 125A, eliminating the need for additional current transformers in many applications.
