- Relay monitors phase sequence and failure, exceeding of monitored voltage in 3 phase main
- HRN-55N - supply L1-N, it means that relay also monitors break of neutral point
- Fixed delay T1 (500ms) and adjustable delay T2 (0.1-10s)
- Faulty state is indicated by LED and output contact of relay is OFF.
- Output contact: 1 x changeover / SPDT 16 A / 250 V AC1
- 1-MODULE, DIN rail mounting
