HRN-55

• 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 1-phase fails.
• HRN-55N: supply L1, L2, L3-N, it means that relay also monitors break of neutral point.
• Fixed delay T1 (500 ms) and adjustable delay T2 (0.1 - 10 s).
