Product leaflet Three phase electricity meters B23/B24 EQ meters in Steel version from ABB The compact and versatile EQ meters B23 and B24 are three phase meters with outstanding performance. They can be used in most of the common applications for reliable and trustworthy metering of energy usage. EQ meters B23/B24 in Steel version can be used in stand-alone applications or metering network installa- tions with the option of inbuilt M-Bus or Modbus. General features ApprApprovalsovals B23 is a three phase direct connected meter up to 65 A The B23 and B24 meters arThe B23 and B24 meters are type appre type approved accoroved according to IECding to IEC and B24 is a three phase transformer connected for 5 A. as well as type approved and verified according to MID. The B23 and B24 are measuring active energy with accuracy MID is the Measure Instruments Directive 2004/22/EC from class B (Cl. 1). The low rated or base currents of these prod- European Commission.
