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

The full-featured monitoring relay is used for 3-phase network control, network monitoring and protection, voltage regulation from a generator or hydropower plant.

EAN: 8594030338216 (230V) | Code: 4733 (230V)
EAN: 8595188120258 (400V) | Code: 2025 (400V)

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).
  • HRN-43: for circuits 3x 400 V (without neutral).
  • HRN-43N: for circuits 3x 400/230 V (with neutral).
