Notes
Note 1: CURRENT RATINGS
IEC/EN 62052-11 defines only Basic, Reference and Maximum currents as follows:
Basic Current (Ib) Direct Connected
Reference Current (In) CT Operated
Direct Connected Maximum current (Imax) shall preferably be an integral multiple of Ib.
Direct Connected A1120/A1140 meters may have Imax values up to a maximum of 100A
CT Operated shall have maximum currents of 1.2 In, 1.5 In and 2 In
CT Operated A1120/A1140 meters may be:
1 - 2A (suitable for use as 1 - 1.2A, 1 - 1.5A, or 1 - 2A)
5 - 10A (suitable for use as 5 - 6A, 5 - 7.5A, or 5 - 10A)
1 - 10A (suitable for use with any of the above 6 ratings)
EN 50470-1 (MID) defines basic values or Itr from which Imin, Iref and Imax can be derived
Imin, Iref and Imax have been chosen so that the following relationships are met
Note 2: VOLTAGE RATINGS
Of the values IEC/EN 62052-11 defines for reference voltages, the following may be accepted
Ref Voltages for meters not connected through current transformers
EN 50470- 1 (MID) defines for reference voltages, the following standards and exceptional values
Ref Voltages for Direct Connected
Meters with marked currents and voltages other than the above values CANNOT be provided when the nameplate
shows the IEC/EN Standard Number.
If a valid requirement exists for meters with marked values within the acceptable ranges, but not listed above, specific
arrangements to provide nameplates not showing the IEC/EN standard must be made.
Note 3: TEST INDICATOR OUTPUT VALUES
The following values are to be used for the Test Indicator LED outputs:
Direct Connected: 1,000 p/kWh (kvarh)
Note 4: SCHEME COMPATIBILITY
Schemes generated for VERSION 'A' meters are not compatible with VERSION 'C' meters
Note 5: SPECIAL ADDITIONS
Early issues of this code used the final (16
voltage terminals".
