Однофазное реле контроля напряжения

Однофазные реле контроля напряжения предназначены для контроля превышения и понижения напряжения. В одном реле одновременно поддерживаются автоматический и ручной сброс. Состояние реле легко контролируется по светодиодному индикатору.

Однофазное реле контроля напряжения
Корпус шириной 22,5 мм для промышленного применения
Обнаружение превышения или понижения напряжения
Номиналы напряжений питания: 24 В~/=, 100 - 240 В~
Простое подключение проводов с обжимными наконечниками
