U-Series MCCB supplies you with wide and powerful production range; 630A, 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.
Surpasses Hi-Series MCCB with superior characteristics.
Optimized design for high breaking capacity in a smaller size.
Minimizes effects from fault currents for cost-effectiveness.
Easy replacement with uniform size across models.
Internationally type-tested for reliability.
