Purpose Current transformers are intended for transmitting a signal of measuring information to measuring devices, protection and control devices and are used in AC networks with a nominal frequency of 50 Hz and a rated voltage of up to 660 V.

Current transformers are installed, for example, in input-distribution devices for accounting for energy consumption.

The company’s product range includes current transformers with a built-in bus – ТТЭ-А, and with a universal window (without a built-in bus) – ТТЭ-30, ТТЭ-60, ТТЭ-85, ТТЭ-100, ТТЭ-125.
