This MicroLogic 7.0Xi is an electronic control unit used on MasterPact MTZ1 drawout circuit breakers. This control unit is compatible with MasterPact MTZ1 06 to MTZ1 16, all in drawout version. MasterPact MTZ is the last generation of high current air circuit breakers up to 6300A embedding advanced digital technologies. MasterPact MTZ is designed to protect electrical systems from damage caused by overloads, short circuits and equipment ground faults. It is possible to customize MicroLogic Xi control unit anytime with digital modules to add new protection, measurement or diagnosis functionalities. MicroLogic XI control units have a wired communication (no Bluetooth) . MicroLogic 7.0Xi has an adjustable long time protection against overloads. It provides also adjustable short-time protection and instantaneous protection against short-circuits. MicroLogic 7.0Xi has an adjustable earth-leakage protection. With its embedded backlight HMI, MicroLogic Xi allows the quick identification of alarm messages. The information processed by the MicroLogic Xi may be displayed on the embedded backlight HMI or a PC through the USB connection. The protections can be set by means of the embedded display or with a PC running EcoStruxure Power Commission, and additionally via Ethernet and Modbus SL communication. MasterPact MTZ and MicroLogic Xi can be used in EcoStruxure architecture system. MasterPact MTZ is part of the global Schneider environmental data program.
