Three-phase electricity meter, CT 1-5A 4M, M-bus, MID ECM300C

Three-phase energy meter – precise measurement and reliability

This three-phase energy meter, designed to work with current transformers in the range of 1-5A, is an advanced solution for measuring energy consumption. Equipped with an M-bus interface, it provides easy integration with monitoring systems and remote reading. It meets the requirements of the MID directive, guaranteeing measurement accuracy and legalization. Ideal for both installers and end-users looking for a reliable and precise device.

Functionality and application

The ECM300C meter is designed to measure electricity consumption and return in three-phase installations with a neutral wire. Thanks to the accuracy class B, it provides reliable measurement results, which is crucial in settlements with the energy supplier and in consumption analysis. Remote data reading via the M-bus interface facilitates real-time energy consumption monitoring and cost optimization. The pulse output (optical) allows integration with building automation systems and load control.

• Versatile application: ideal for homes, commercial buildings, and industrial facilities.
• Measurement accuracy: accuracy class B ensures compliance with standards and precise billing.
• Remote reading: M-bus interface enables remote energy consumption monitoring.
• MID legalization: guarantee of measurement reliability and compliance with regulations.
• Multi-tariff: possibility of configuring different energy consumption tariffs (T1...T2), allowing for cost optimization depending on the time of day or day of the week.
• Meter tampering protection: protection against manipulation and unauthorized interference with measurement results.

Technical characteristics and installation

The ECM300C meter is characterized by a compact design, occupying 4 modules on a DIN rail (72 mm wide, 90 mm high, 60 mm deep). Mounting on a DIN rail is quick and easy, making installation easier even in difficult conditions. The device operates in the frequency range of 45-65 Hz and rated voltages of 92-276 V (N-L) and 160-480 V (L-L). The maximum measurement circuit current is 6 A at a rated current of 5 A. Made of high-quality materials, it ensures durability and reliable operation even in demanding environmental conditions (operating temperature -25°C to +55°C). Protection class IP20 provides protection against finger contact.
