380V is used for three-phase transparent meter boxes. At the same time, the specifications of meter boxes with circuit breakers may include ordinary/cost control three-phase 1-bit, three-phase 2-bit, three-phase 4-bit, three-phase 8-bit, three-phase 12 bit, etc.

In the projects we have done, the electricity meter boxes with circuit breakers account for a large proportion of the total, and are more cost-effective.
