3-phase sequence, phase-loss relay, 22,5mm Screw terminals

The K8AK-PH1 monitoring relay is designed to monitor 3-phase 3-wire supplies. It simultaneously monitors phase sequence and phase loss during start up as well as phase loss during operation. The output relay releases when alarm conditions are detected, and the warning status can easily be monitored using the LED indicator. Suitable for industrial facilities and equipment.

  • Monitors phase sequence and phase-loss simultaneously

  • Measuring range: 200 to 480 VAC

  • Power supply voltage is the same as measuring voltage

  • Operation reaction time: 0.1 s maximum
