The meters are designed for single-tariff measurement of active electric energy in three-phase three- and four-wired AC networks. The meters are designed for indoor operation and can be installed in the areas with additional environmental protection (installed inside premises, cabinets or boards).
The meter modifications are available with different rated voltage, rated and peak current.
