24 Vdc Power Supply Connector
Introduction
The 24 Vdc power supply connector connects the MicroLogic 5, 6 or 7 trip unit to an external 24 Vdc power supply to allow it to be powered when the circuit breaker is open or when the current is low (15 to 55 mA depending on the rating).
The commercial reference for the 24 Vdc power supply connector is LV434210.
The MicroLogic 5, 6 or 7 trip unit is powered by the current through the internal current transformers to provide the protection functions when the circuit breaker is closed.
An external 24 Vdc power supply is optional for:
-
Modifying the settings when the circuit breaker is open.
-
Displaying measurements when there is a low current through the closed circuit breaker.
-
Displaying the trip cause and the breaking current when the circuit breaker is open after a trip.
For more information about installation, consult the instruction sheet on the Schneider Electric website: GHD16256AA 24 Vdc Terminal Block and SD Auxiliary Contact for BSCM Modbus SL/ULP.
Installation
The slots used to install the 24 Vdc power supply connector depend on the circuit breaker type.
