The 380 plug-in meter will automatically cut off power after a period of time, and it must be plugged in to talk.

A: Three-phase meters will automatically cut off power for the following reasons:

1. There is something wrong with the meter itself, so it cannot use high power.

2. The energy transmitted by the wires in your home is too low. As soon as the high-power electrical appliance is started, the overload will trigger the leakage protection of the electric meter. 3. There is a short circuit, resulting in power failure. It is recommended to check it to ensure the safety of electricity use. If the problem is not solved, it is recommended to contact the power supply company.
