Features

Sequence relay-phase, phase loss

The relay monitoring K8AB-PH1 is designed to control power supplies three-phase 3-wire. Simultaneously, controls the phases sequence and phase loss during start-up, as well as phase loss during operation. The output relay is disconnected, if detected alarms and the warning state can be easily controlled by using the LED indicator. Suitable for computers and industrial facilities.

  • Controls the phases sequence and phase loss simultaneously
  • Measurement range: 200 - 480 V ac
  • The supply voltage is the same voltage as
  • Reaction time of the operation: 0.1 s maximum
