Monitoring voltage relay HRN-55N

• relay monitors phase sequence and failure, exceeding of monitored voltage in 3
phase main
• 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
• fi xed delay T1 (500 ms) and adjustable delay T2 (0.1 – 10 s)
• faulty state is indicated by LED and output contact of relay is OFF
• output contact: 1x changeover / SPDT 8 A / 250 V AC1
• 1-MODULE, DIN rail mounting
