The new worldwide benchmark for high current circuit breaker (ACB)
Building on the legendary performance and reliability of the MasterPact range, MasterPact MTZ circuit breakers are Future Ready. Incorporating the latest digital and communication technologies, they are key components within Schneider Electric’s Smart Panels, contributing to smart operation, power uptime and energy efficiency.
MasterPact MTZ circuit breakers connect your electrical switchboard to any building and energy management system.
A simple smart phone can act as the main HMI to monitor and control MasterPact MTZ, giving you maximum convenience and ease of management, even in the event of a power outage. The MicroLogic X control units are customizable with additional digital modules available.
The standardization of electrical switchboards remains the same with MasterPact MTZ circuit breakers keeping the same size frames, standardized auxiliaries and accessories, providing peace of mind for choice, installation, retrofit and operation.
