MicroLogic Display

Presentation

The MicroLogic display operates without an external power supply.

The display goes off if the current drops below 0.2 x In (In = rated current).

An optional 24 Vdc external power supply may be used to maintain the display of currents even when the current drops below 0.2 x In.

For more information on connecting an external power supply, refer to the electrical diagrams in DOCA0221EN ComPacT NS - Circuit Breakers and Switch-Disconnectors - User Guide .

Back-Lighting and Maximeter

Display back-lighting is disabled in the following situations:

  • Current less than 1 x In on one phase

  • Current less than 0.4 x In on two phases

  • Current less than 0.2 x In on three phases

The maximeter does not operate for currents under 0.2 x In.

NOTE: The display back-lighting and the maximeter may be maintained, whatever the current, by adding a 24 Vdc external power supply.
