Schneider Electric A9MEM3110 IEM3110 Three Phase Energy Meter 63A

Product Overview:

The Schneider Electric A9MEM3110 (iEM3110) is a small three-phase DIN-rail energy meter that is made for accurately sub-billing and allocating costs for active energy in commercial and industrial settings.

The A9MEM3110 is part of the Acti 9 iEM3000 series and has Class 1 accuracy for measuring active energy. This makes it great for sub-billing and partial metering. It can measure up to 63 A directly without needing external current transformers, which makes it easier to install in distribution boards. The meter works with 1P+N, 3P, and 3P+N networks at 50/60 Hz and has a wide voltage range of 100–277 V (phase–neutral) or 173–480 V (phase–phase), making it work with most low-voltage systems. The clear LCD screen and pulse output make it easy to read locally and connect to BMS, PLC, or data-logging systems for energy management.

Key Features of A9MEM3110 Three Phase Energy Meter:

1) Direct 63 A measurement: For loads up to 63 A, you don’t need any current transformers, which makes wiring easier and cheaper.

2) Class 1 accuracy: Meets the IEC 62053-21 and EN 50470-3 Class B standards for reliable sub-billing and MID-compliant uses.

3) The open collector gives proportional pulses for connecting to PLCs, BMS, or data loggers.

4) Wide voltage range: Works with 1P+N, 3P, and 3P+N networks at 50/60 Hz and can handle 100–277 V L-N or 173–480 V L-L.

5) 8-digit LCD screen: You can easily see the total kWh, partial counters, and status in your area with navigation keys.

6) LED lights: A green power/status light and a yellow flashing light for pulse verification and quick checks.

7) The front is rated IP40 and the body is rated IP20. The size is 90 mm wide (10 modules) and 95×69 mm.

8) Strong performance: works well in temperatures from −25 to 55°C and humidity levels from 5% to 95%. Perfect for industrial automation panels.

Industrial Uses:

1) OEMs and machine builders: Monitors energy use for OEE optimization and energy-efficient design on each machine or production line (like conveyors and pumps).

2) Process plants: Keeps track of sub-mains for compressors, chillers, and utilities so that costs can be divided up and energy audits can be done according to ISO 50001.

3) Panel builders: Puts in MCC/PLC panels for feeder-level metering in automated systems like assembly or packaging lines.

4) Commercial buildings: Sub-billing in tenant boards, AHU/lighting panels for load profiling, and facility management.

5) Utilities and data centers: Partially metering important loads for benchmarking, managing demand, and reporting on the environment.
