Product OverviewThe Hyundai 350A HGM400E 3 Pole Molded Case Circuit Breaker (MCCB) is a heavy-duty, fixed-type industrial circuit protection device engineered by HD Hyundai Electric. Designed to manage high-capacity electrical loads in both residential and industrial environments, this premium MCCB provides reliable protection and control of electrical machinery against overloads, short circuits, and optional ground faults. It serves as a critical safety component in main low-voltage switchgears, heavy motor control centers, and high-output generator distribution systems. With a high rated current of 350 Amps and a robust short-circuit breaking capacity of 30kA, the HGM400E ensures immediate fault isolation. This limits downstream equipment damage, reduces costly operational downtime, and maintains safety across large-scale electrical networks.
