Three phase electricity meters A43 and A44
EQ meters in Bronze version from ABB
The compact and versatile EQ meters A43 and A44 are
three phase meters with full four quadrants measuring
meaning both active/reactive energy measurements and
import/export of energy. They can be used in most of
the common applications for reliable and trustworthy
metering of energy usage.
EQ meters A43 and A44 in Bronze version can be used
in stand-alone applications or metering network instal-
lations with the option of inbuilt M-Bus or Modbus.

The A43 and A44 meters are type approved according to IEC
M-Bus A44 213 - 100 2CMA170535R1000 0.35
as well as type approved and verified according to MID.
MID is the Measure Instruments Directive 2004/22/EC from
European Commission. The type approval is according to
standards that covers all relevant technical aspects of the
meter. These include climate conditions, electromagnetic
compatibility (EMC), electrical requirements, mechanical re-
quirements and accuracy.A series
