Energy Meters ME

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.

ME Kilowatt hour meters: a complete range Direct three-phase+neutral ME4 63A Direct three-phase ME3 63A Direct single-phase ME1 63A Class 1 40 to 6000A Through CT’s three-phase+neutral or three-phase ME4zrt

ME Energy Meters The ME kilowatt hour meters: comply with the IEC 61557-12 standard are available in 8 versions, according to their options: Single-phase 3-phases 3-phases + N Global Meter ME1 ME3 ME4 + Partial meter ( with reset: zero ) ME1z + Remote ( remote transfer ) ME1zr ME3zr ME4zr Partial meter + Remote + CT ME4zrt ( zrt ) DIRECT 63 A Via CT

Improvements on the last version Class 1 Lead sealing accessory (for direct measurement versions) Complies with new standards: IEC 61557-12 & IEC 61557- 21 (accuracy) Marking improvement Icons rather than text when possible rather than Imp. Rather than Pulse Clarification: Imax: 63A Ib: 10A rather than 10(63)A Adding of the consumption in VA Individual date – code Note about the individual calibration and tester reference Instruction leaflet improvement More languages: 16 More technical data’s: ex I start Explanation about the flashing meter indicator utilization Explanation about error messages
