• [A] / [kA], and when
• [kW] and [MW]

1. The display format for current depends on the parameter for the CT configuration. If the Ampere for the primary side of the CT is configured >1000 Ampere, then the HMI display will switch from "A" to "kA".
   
   
2. The display format for the active power depends on the actually measured power. If the measured power gets  higher than 1000 kW, then the HMI display will switch from "kW" to "MW".

This is a fixed internal function which cannot be configured, as the space on the display is limited, and otherwise it would be bad to read; high values need to be shown as kA/MW.
