Monitoring voltage relay HRN-55N

Relay monitors phase sequence and failure ( e.g monitoring of correct motor winding etc.)in 3 phaze main

DESCRIPTION

  • Monitoring of correct motor winding etc..
  • fixed delay T1 (500ms) and adjustable delay T2 (0.5-10s).
  • Monitoring voltage relay in two variants:

HRN-55: supply from all phases, which means that function of relay is applicable also if one phase fails.
HRN-55N: supply L1-N, it means that relay also monitors break of neutral point. 

  • Faulty state is indicated by LED and output contact of relay is OFF.

TECHNICAL PARAMETERS

  • Monitored power voltage: 

HRN-55: 3 x 400 V 
HRN-55N: 3 x 400 V/ 230 V

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