Single phase electricity meter:
Function: Single phase electricity meters are mainly used to measure the electrical energy in single-phase circuits, with a rated voltage of 220V, monitoring single-phase voltage and single-phase current.
Wiring method: Single phase electric meters usually have four wiring terminals (L in, L out, N in, N out), and current through type is more common
one.

Scope of application: Suitable for single-phase load scenarios such as residential buildings and shops one.
Three phase electricity meter:
Function: A three-phase electricity meter can monitor three-phase voltage and three-phase current, with various specifications including 100V to 380V and other voltage specifications. The functions of three-phase electricity meters are more diverse, including data freezing, over limit alarm, harmonic measurement, etc one.
Wiring method: The three-phase meter has four voltage terminals (VA, VB, VC, VN) and six current terminals (IA, IB, IC).
