Electroaparataj was incorporated in 1948 as a manufacturer of low-voltage switching equipment.

With a range of products developed by its own research and development department, it was a market leader until 1990, when it reduced some of its manufacturing capabilities because of the competition from multinational companies which came to Romania.

Fully privatized in 1997, Electroaparataj developed its low-voltage production capabilities and technologies related to low-voltage equipment and the related services; thus, it initiated OEM collaborations.
