Voltage monitoring relay HRN-43/230V /4729/

• 
  The relay monitors in 3-phase networks:
  - voltage in two levels (overvoltage and undervoltage) in the range of 138 - 276 V (3x 400/230 V system) or 240 - 480 V (3x 400 V system)
  - phase asymmetry (can be switched off) - phase sequence - phase failure.
• Function of the second relay (separate/parallel).
• HRN-43: designed for 3x 400 V circuits (without neutral conductor).
• Galvanically isolated power supply AC 400 V, AC 230 V, AC/DC 24 V.
