Hyundai UCB250LF High Breaking Capacity Adjustable Thermal MCCB Model
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.
U-Series MCCB minimizes the difference in size of each model, so that they can be easily replaced whenever the specifications of the system changes. U-Series MCCB is type-tested by international test authorities such as KEMA and KERI as well satisfying IEC60947-2 and NEMA AB-1 standards. It also acquired various marine classes and certificates for nuclear power plants.
