- Чередование фаз, обрыв фаз: Максимальное рабочее время срабатывания составляет 0,1 с
- Асимметрия: время срабатывания регулируется в пределах от 0,1 до 30 с
- Способ сброса: автоматический
- Светодиодные индикаторы: электропитание (зеленый), выход реле (желтый), выход аварийной сигнализации (красный)
- Температурный диапазон: от -20 до 60 гр.ц.
- Корпус 17,5 мм (ширина)
- Повышенное сопротивление помехам от инвертора
- Одно устройство поддерживает множество мировых стандартных номиналов электропитания
