Monitoring voltage relay HRN-54N

Serves to monitor voltage , phase failure and sequence in switchboards, protection of devices

DESCRIPTION

  • Serves to monitor voltage , phase failure and sequence in switchboards. 
  • Supply is done from monitored voltage.
  • Fixed T1(500ms) and adjustable T2 (0.1 – 10 s) delay to eliminate short voltage drops and peak.
  • In case supply voltage falls below 60 %Un (Uoff lower level)relay immediately breaks with no delay
  • It is possible to set upper and lower level of monitoring voltage.
  • Monitoring voltage relay in 2 variants:

HRN-54: supply from all phases which means that relay is functional also in case when one phase is faulty
HRN-54N: supply L1-N, means that relay monitors also failure of neutral wire

  • Faulty state is indicated by red LED and by breaking output relay contact.

TECHNICAL PARAMETERS

  • Monitored power voltage: 

HRN-54: 3 x 400 V 
HRN-54N: 3 x 400 V/ 230 V

  • Umax: 105 – 125% of monitored voltage.
  • Umi): 75 – 95% of monitored voltage.
  • Output contact: 1x changeover 8 A/250 V AC1 (AgNi, 2500 VA).
  • 1-MODULE, DIN rail mounting.
