Three-phase electronic energy meters SEA3 are electrical products that are analogue digital devices that produce summation and indication on the electromechanical readout device of the amount of electricity consumed directly in kilowatt hours.

Accounting for active electricity at a single tariff in three-phase three- or four-wire AC circuits directly or through current and voltage measuring transformers, either autonomously or as part of information and measurement systems as a sensor for energy increment and power measurement. Three-phase, static, electronic energy meters SEA33 are electrical products representing analog-digital devices that produce summation and indication on an electromechanical reading device or electronic display of the amount of electricity consumed directly in kWh.
