PRODUCT OVERVIEW
MasterPact UR
Ultra-fast current-limiting ACB platform for 5000 A and 6000 A high short-circuit applications.
MasterPact UR combines a MicroLogic control unit with a dedicated UR control and energy module for ultra-fast operation. It is a project-engineered solution rather than a direct substitute for a standard ACB.
