Voltage Relay for three-phase current also for alternating current networks

  Modern electrical switchgear for energy generation and distribution, for treatment and processing machines and for a variety of other drives are usually equipped with measuring and control-engineering devices.
  However, the use of such devices demands that the supplied mains voltage deviates only slightly from the nominal value as otherwise the required accuracy of the measurements or the actuating signal is not attained, or downstream units are destroyed by overvoltage.

FEATUREs:
• Monitoring three-phase current networks 3 AC 400 V
   with neutral conductor
• Monitoring alternating current networks AC 230 V
   (connect inputs L1/2/3)
• Monitoring own power supply
• Switching point fixed 80 %
• Output relay 2 change-over contacts
• Panel mounted housing, 35 mm wide
