Crompton Instruments 239 Series Meter Relay - AC Ammeters

Crompton 239 ACA*

The Crompton Instruments 239 series meter relays combine a highly accurate indicator with High and Low set point relays. The relays can operate alarm and control devices when the monitored signal value moves outside the chosen set point limits shown by adjustable red index pointers. A single compact case houses the unit which requires only the input signal and power supply, thus saving space and installation time.
