1. Energy Meters ME

2. Aims You need to keep control of your power consumption,
to follow the power consumption by sector, unit, workshop,
to better manage your electrical installation and optimize your building energy efficiency
Schneider Electric has designed the ME for the sub-metering of active energy (rms) consumed by a single phase or three phases electric circuit.

3. Scope of application Commercial & Industry
shops in shopping centers, airports, railway stations, hospitals …
Shared spaces, offices, workshops, machines
Energy Efficiency (new rules to save energy in some countries)
Exhibitions
Trade and fun fairs,
camping sites, mobil-homes, caravans, bungalows,
weekly street market,
marinas, quaysides.
energy generation: windmills, solar energy, photo-voltaics, fuel …
