ERMS installation on Masterpact MTZ breaker

Published date: 22 May 2020

Issue:
How to implement ERMS on Masterpact MTZ

Product Line:
Circuit Breakers

Environment:
Masterpact MTZ

Resolution:
The ERMS function on an MTZ breaker requires the ERMS digital module LV850009.  ERMS can be controlled with the Schneider Ecostruxure Power Device smart-phone app.  
For local control and indication via an external switch, the breaker also requires the ESM module plus switch components as indicated in the installation bulletin. This should be ordered factory installed as it is much easier, but alternatively it can be field installed.  Please refer to document PHA58571 for installation and connection of the ESM module to local switch and indication.   See attached for ESM installation and components required.
