Issue:
How to implement ERMS on Masterpact MTZ

Product Line:
Circuit Breakers

Resolution:
The ERMS function on an MTZ breaker requires the ERMS digital module LV850009. ERMS can be controlled with

• with the Schneider Ecostruxure Power Device smartphone app
• with a physical switch

The customer-supplied physical switch option allows the user to remotely engage/disengage the circuit breaker’s ERMS function.
The EcoStruxure Power Device App allows a user to engage and disengage the ERMS function via Bluetooth wireless communications using an Android or iOS compatible device.
