Telemecanique A9MEM3310 is an Acti 9 iEM3000 series electronic energy meter (iEM3310) designed for accurate monitoring of active energy in electrical distribution panels. Suitable for sub-billing and partial metering applications, it supports 1P+N, 3P, and 3P+N configurations with a direct-connected rated current of 125 A and a rated voltage range of 100–277 V or 173–480 V at 50/60 Hz. The unit features a clear LCD display, 32 samples per cycle measurement, and a single pulse output for straightforward energy reporting, with local status indication via a green power LED and a yellow flashing LED for accuracy checking. It is DIN-rail, clip-on mounted with screw terminals up to 50 mm², offers overvoltage category III performance, and meets relevant metering and monitoring standards including IEC class 1 accuracy and MID class B requirements.

What does this device measure?
It measures active energy consumption (kWh) using an electronic metering method, making it suitable for tracking electricity usage over time.
Which electrical systems can it be used on (single-phase or three-phase)?
It supports multiple pole configurations: 1P + N, 3P, and 3P + N, so it can be applied to both single-phase and three-phase installations depending on how it is wired.
What voltage ranges are supported?
The rated voltage ranges are 100…277 V and 173…480 V, covering many common low-voltage distribution systems.
What is the maximum current rating and measurement range?
It is rated for 125 A with direct current measurement from 0…125 A (direct input, no external CTs required within this range).
Does it work on both 50 Hz and 60 Hz supplies?
Yes. It is designed for 50/60 Hz networks.
What accuracy classes does it meet for active energy metering?
Active energy accuracy is Class 1 to IEC 62053-21 and IEC 61557-12, and Class B to EN 50470-3.
Is it suitable for sub-billing or allocating energy costs within a facility?
Yes. It is intended for sub-billing and partial metering applications, commonly used for cost allocation across tenants, panels, or internal departments.
Does it have a communications port (such as Modbus)?
No. This variant does not provide a communication port protocol or communication port support; it focuses on local display plus a pulse output.
What outputs are available for external monitoring or logging?
It provides 1 pulse output, which can be used for external counting or simple energy logging via a compatible pulse counter/PLC input.
What local indications are provided on the front?
It includes an LCD display plus local LEDs: a green indicator for power ON and a yellow flashing LED for accuracy checking.
What is the maximum energy value it can display?
The maximum value measured is 99,999,999.9 kWh.
How is it mounted in a panel?
It is DIN-rail mountable with a clip-on mounting mode, designed for straightforward installation in distribution boards.
What type of terminals and cable size does it accept?
It uses screw terminals and supports cables up to 50 mm².
What is the IP rating of the unit?
The front panel is rated IP40 and the body is rated IP20 (per IEC 60529).
What environmental conditions is it designed to operate in?
Typical operating ambient ranges are -25…60 °C (IEC/NMI) and -25…55 °C (MID), with relative humidity 5–95% at 50 °C and operating altitude up to 2000 m.
What are the approximate dimensions for panel planning?
It is approximately 126 mm wide, 103.2 mm high, and 69.3 mm deep, occupying 14 pitches of 9 mm. The catalogue reference for this configuration is A9MEM3310.
