U-Series MCCB supplies you with wide and powerful production range; 3 to 1600A, 5 to 150kA at AC415V from general distribution boards to nuclear power plants. U-Series MCCB also completely covers Hi-Series MCCB range with better characteristics. Our optimized design by advanced current-limiting technology allows U-Series MCCB to realize high breaking capacity in a smaller size compared to Hi-Series MCCB, contributing to compact design of system. The current-limiting characteristic of U-Series MCCB also minimizes the effects from fault currents and offers cost-effectiveness.
Wide production range: 3 to 1600A, 5 to 150kA at AC415V.
Versatile application: from general distribution boards to nuclear power plants.
Better characteristics than Hi-Series MCCB.
Optimized design: advanced current-limiting technology for high breaking capacity.
Minimized effects from fault currents, offering cost-effectiveness.
Easy replacement: minimized size difference between models.
