Energy meter IEM3335 125A MBUS MID A9MEM3335

Three-phase energy meter for precise measurement and billing

The IEM3335 125A energy meter is an advanced device designed to measure electricity consumption in three-phase installations. Designed for both professional installers and end-users, it offers reliability, accuracy, and a wide range of functions to facilitate energy monitoring and optimization. Equipped with an M-Bus interface, it enables easy integration with building automation systems and remote data reading.

Functionality and application

This meter is an ideal solution for applications in commercial buildings, industrial plants, and residential installations with higher energy demands. Thanks to the ability to measure active and reactive power, it allows for a comprehensive analysis of the load profile. Support for multi-tariff billing (controlled externally or internally) enables optimization of energy costs by billing consumption depending on the time of day or day of the week. The meter is designed for direct mounting on a DIN rail, which simplifies its installation and replacement.

Key features and benefits

• Measurement accuracy: Accuracy class B ensures reliable and precise measurements of active energy, which is crucial for correct billing of consumption.
• M-Bus communication: The M-Bus interface enables easy integration with energy monitoring systems and remote data reading, which translates into time and cost savings.
• Multi-tariff billing: The ability to configure tariffs allows for optimization of energy costs by billing consumption depending on the time of day or day of the week – particularly important for companies with high energy demand at specific times.
• Wide voltage range: Support for rated voltages of 100…277 V (N-L) and 173…480 V (L-L) makes the meter universal and can be used in various types of electrical installations.
• Safety and compliance with standards: It has MID (Measuring Instruments Directive) approval, which guarantees compliance with European metrological and legalization standards.
• Solid construction: The housing with a protection degree of IP20 provides protection against touch and dust, and a width of 7 modules facilitates mounting in electrical switchboards.
• Pulse output: An available D0 type pulse output allows integration with external data logging and control systems.
• Rated current 125A: Direct current measurement up to 125A eliminates the need for additional current transformers in many applications, simplifying installation and reducing costs.

The maximum current (Imax) is 125 A, and the rated voltage range is 100…277 V (N-L) and 173…480 V (L-L). Communication is via an M-Bus interface, and the accuracy class is B. The meter is 126 mm wide (7 modules) and has a protection degree of IP20.

This meter is not only a tool for measuring energy consumption, but also an element of an energy management system that allows you to identify areas for potential savings and optimize the operation of the electrical installation. Thanks to its functionality and reliability, it is an investment that quickly pays for itself by reducing energy costs.
