The Micrologic 6.0 X is an electronic control and trip unit used with the MasterPact MTZ fixed circuit breakers. The Micrologic 6.0 X has adjustable long-term protection, short-time delayed and instantaneous short-circuit protection, as well as earth fault protection. This control unit is compatible with MTZ1 06 to MTZ1 16, MTZ 08 to MTZ2 40, MTZ3 40 to MTZ3 63. MasterPact MTZ is the latest generation of air circuit breakers up to 6300 A, incorporating advanced digital technologies. MasterPact MTZ is designed to protect electrical installations from damage caused by overloads, short circuits and earth faults. It is possible to adapt the Micrologic X control units at any time with digital modules to add new protection, measurement or diagnostic functions. The Micrologic X control units have several communication channels, including Ethernet, Modbus SL and wireless communication facilities. With its integrated backlit HMI, Micrologic X allows for quick identification of alarm messages. The information processed by Micrologic X can be displayed on the integrated backlit HMI, on a smartphone via Bluetooth or NFC, and on a PC via the USB port. The protection functions can be set via the integrated display, a smartphone via Bluetooth or with a PC, with the EcoStruxure Power Commission and additionally via Ethernet and Modbus SL communication. MasterPact MTZ and Micrologic X are part of the EcoStruxure architecture system.
