Three-phase multifunctional electricity meters I-SM 3XX, depending on the model, are intended for the measurement and accounting of active and reactive energy in both forward and reverse directions in three-phase four-wire alternating current circuits with a frequency of 50 Hz and for the implementation of multi-tariff metering.

The meters are also intended for the conversion, storage, and transmission of information via built-in interfaces, both independently and within automatic control and data collection systems.

Scope of application: electricity metering at industrial enterprises, utility facilities, and energy facilities, including the exchange of information via communication channels as part of automated commercial electricity metering systems (AMR).
