application scenarios:

deployed as the primary protection component in data centers and incoming cabinets of communication rooms to ensure power supply safety for high-density computing equipment; installed in main distribution rooms of steel metallurgy plants, petrochemical facilities, and large-scale manufacturing plants to provide first-level protection for heavy industrial loads; applied in urban municipal power distribution hubs, commercial complexes, and rail transit substations to coordinate power security for large building complexes and public facilities; widely used in the main grid-connected circuits of new energy distribution systems such as photovoltaic and energy storage systems to safeguard stable power transmission. As the core protection device at the top level of low-voltage distribution systems, frame circuit breakers have become standard components in high-power distribution projects due to their comprehensive advantages of high current capacity, robust protection capabilities, and intelligent functionality.
