  • Order code: AC Voltage Relay with adjustable Differential
  • Brand:
  • Country: Germany
  • AC Voltage Differential Relay provides continuous surveillance of the monitored circuit . When the measured voltage moves outside the set point limit , the relay will operate giving an alarm and or initiation signal . An illuminated LED indicates when the relay is energised . The 3 Phase, 3 or 4 wire models protect each phase independently .

  • Model: AC Voltage Relay With Adjustable Time Delay
  • Order code: AC Voltage Relay With Adjustable Time Delay
  • Brand:
  • Country: Germany
  • AC Voltage Protection Relay provide continuous surveillance of circuit . When the measured voltage the monitored moves outside the setpoint limit , the relay will operate after the selected time delay , giving an alarm and or initiation signal . Relays normally energise on over volts and de-energise on under volts . An illuminated indicates when the relay is LED energised . 3 phase 3 or 4 wire models protect each phase independently.
