The Micrologic 2.0 X is an electronic control and tripping device used in the MasterPact MTZ circuit breakers with plug-in technology. It features adjustable long-time protection and short-circuit protection. This control device is compatible with MTZ1 06 to MTZ1 16, MTZ 08 to MTZ2 40, and MTZ3 40 to MTZ3 63. MasterPact MTZ represents the latest generation of open circuit breakers up to 6300 A, integrating advanced digital technologies. It is designed to protect electrical installations from damage caused by overloads, short circuits, and ground faults. The Micrologic X control devices can be customized at any time with digital modules to add new protection, measurement, or diagnostic functions. They offer multiple communication channels, including Ethernet, Modbus SL, and wireless communication facilities. With the integrated HMI featuring backlighting, the Micrologic X allows for quick identification of alarm messages. The processed information can be displayed on the integrated HMI, on a smartphone via Bluetooth or NFC, and on a PC through the USB port. The protection functions can be set via the integrated display, a smartphone through Bluetooth, or with a PC using EcoStruxure Power Commission, as well as through Ethernet and Modbus SL communication. MasterPact MTZ and Micrologic X are part of the EcoStruxure architecture system.
