Voltage monitoring relay for complete control in 3P incl. asymmetry HRN-43

3 x 84 - 480 V
without NEUTRAL

DESCRIPTION

  • Monitoring of 3-phase mains:
    - voltage in 2 levels (undervoltage and overvoltage) in range 138-276 V (3x 400 V/230 V) or 280-480 V (3x 400 V)
    - phase asymmetry (can be switched off )
    - phase sequence
    - phase failure.
  • Function of second relay (independent/parallel).
