Can ERMS be activated with a physical switch on an Masterpact MTZ breaker?

Published date: 19 June 2020

Issue:
On an MTZ breaker ERMS is normally activated by use of a smart-phone; can it be activated with a physical switch like it was with Masterpact NW?

Product Line:
Circuit Breakers

Environment:
Masterpact MTZ

Resolution:
Yes, it can be activated by installing the ESM module, LV836300SP.  It will allow activation and deactivation of ERMS by means of a push button.
The breaker can be ordered with this option from the factory. If not factory installed, it will require a Schneider Services call to install it in the field.
See attached for details.
