The Hyundai UCB800HF 3 Pole Molded Case Circuit Breaker offers a wide production range from 3 to 1600A, with a breaking capacity of 5 to 150kA at AC415V, suitable for applications ranging from general distribution boards to nuclear power plants. Surpassing the Hi-Series MCCB range with superior characteristics, its optimized design and advanced current-limiting technology ensure high breaking capacity in a smaller size, contributing to a compact system design. The current-limiting feature minimizes the effects of fault currents, enhancing cost-effectiveness. With uniform size across models, it allows for easy replacement to adapt to changing system specifications. Type-tested by international authorities and compliant with standards such as IEC60947-2 and NEMA AB-1, it holds various marine certifications, making it suitable for diverse environments, including nuclear power plants.
