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.
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).
Galvanically separated supply voltage AC 400 V, AC 230 V, AC/DC 24 V
