Откуда уставка 2,6А - из проекта или...сами выставили.

Ну и в первую очередь нужно проверить установку трансформатора тока земляной защиты (ТЗ) и поводок с оболочки кабеля должен проходить через ТЗ и заземляться, иначе будут ложные срабатывания.

Всем спасибо за ответы. Уставку выбирали проектную. Ушли от проблеммы, установив реле ЭТД-551/60. )))
