Scope of Use
■ 220V 2.5(10)A----10(100)A is for direct connected meters suitable for residential energy measurement
at urban or rural areas.
■ 220V 1.5(6)A is for transformer operated meters suitable for small low-voltage electric power utility
at 0.4kV or suitable for the case when one 3-phase 4-wire meter is replaced by three single-phase
meters.
