The power distribution cabinet is the core distribution device in the power system, which is used to centrally receive, control and distribute electric energy. It integrates circuit breakers, protection devices, instruments and other components to achieve circuit on/off, overload/short circuit protection and power consumption monitoring functions to ensure the safe transmission of electricity to terminal equipment. It is widely used in industries, commercial buildings, data centers and other fields, and is a key infrastructure to ensure power supply reliability and management efficiency.
