Purchasing and Installing Digital Modules (MasterPacT MTZ)

Overview

Digital Modules are optional modules that expand the features available across the range of MicroLogic X control units. They can be purchased along with the MasterPacT MTZ circuit breaker in the initial order or at a later date by contacting the Customer Care Center (CCC).

Digital Modules designed for the MicroLogic X control unit are digitally signed for added security using the Schneider Electric public key infrastructure (PKI). The PKI helps to ensure both the authenticity and integrity of these downloads. The Digital Modules must be installed using EcoStruxure Power Commission software.
