Three-phase electronic meters of active energy СТ-ЭА05, СТ-ЭА08, accuracy class 1,0, are designed to record active energy in three-phase three-wire and four-wire mains of alternating current with direct connection and connection through current transformers. The meters may be installed for industrial and domestic consumers, including meters embedded into the automated energy control and record systems.

The meters are protected against magnetic field impact, provide energy measurement under the current load direction change. Meters with an electromechanic counting mechanism are supplied with backstop, which excludes energy stealing.

The meters have indicating lights of voltage availability and load current.

Meters СТ-ЭА05, СТ-ЭА08 meet the requirements of State Standard GOST 30207 and СОУ-Н-МПЕ40.1.35.110:2005, certified for the compliance of the measurement equipment with the approved type, and they have been included into the State register.
