Why can the distribution box play a warning role?

In many equipment, the distribution box will be used. When it is installed in some products, it can not only interrupt the power supply, but also assemble the switchgear, measuring instruments, protective appliances and auxiliary equipment in the enclosed or semi enclosed metal cabinet or panel according to the electrical wiring requirements, so that it can form a low-voltage distribution box.

When it is in normal operation, it can turn on or off the circuit with the help of manual or automatic switch. In case of fault or abnormal operation, it can turn off the circuit or give an alarm with the help of protective electric appliance. By means of measuring instruments, various parameters in operation can be displayed, and some electrical parameters can be adjusted to prompt or send signals for deviation from normal working state. It can also adjust some electrical parameters, prompt or signal the deviation from the normal working state to solve these problems.
