Distribution Box Principle

A distribution box is a low-voltage distribution box that assembles switching equipment, measuring instruments, protective devices, and auxiliary equipment in a closed or semi-closed metal cabinet or panel according to electrical wiring requirements. During normal operation, circuits can be connected or disconnected manually or automatically. In case of faults or abnormal operation, protective devices will disconnect the circuit or trigger an alarm. Measuring instruments can display various operating parameters, allow adjustment of certain electrical parameters, and provide alerts or signals for deviations from normal operating conditions.
