Monitoring voltage relay
HRN-43

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

DESCRIPTION

  • Monitoring 3-phase mains:

a)    Voltage in 2 levels: overvoltage and undervoltage
b)    phase asymmetry
c)    phase sequence
d)    phase failure

  • Function MEMORY – manual reset, “RESET” button on front pannel.
  • Selectable function of 2nd relay (independent / parallel)
  • Fixed T1(200ms) and adjustable T2 (0.1 – 10 s) delay to eliminate short voltage drops and peak.
  • Monitoring relays in 2 variants:

HRN-43: for circuits 3x400 V (without neutral)
HRN-43N: for circuits 3x400/230 V (with neutral)

TECHNICAL PARAMETERS

  • Power voltage AC 230 V, AC 400 V, AC/DC 24 V, galvanically separated
  • Umax: 

HRN-43: 240 – 480 V 
HRN-43N: 138 – 276 V

  • Umin: 35 – 99% monitored voltage.
  • Output contact: 2x changeover 16 A/250 V AC1 (AgNi, 2500 VA).
  • 3-MODULE, DIN rail mounting.
